What Is a Stainless Steel Cutting Disc?
A stainless steel cutting disc is a thin, resin-bonded abrasive tool designed specifically for cutting austenitic stainless steels, such as grades 304 and 316. Typically mounted on an angle grinder or a chop saw, it performs cutting operations through high-speed rotation.
Why use a resin bond?
The resin bond holds abrasive grains (such as zirconia alumina) together while offering self-sharpening properties; as the bond wears down during cutting, new, sharp abrasive grains are exposed, maintaining consistent cutting power. Compared to ceramic or metal bonds, resin bonds offer superior toughness, allowing them to withstand the impact and vibration associated with high rotational speeds.
Why use fiberglass reinforcement?
Stainless steel cutting discs feature embedded layers of fiberglass mesh designed to withstand centrifugal forces at high speeds. These stainless steel cutting discs operate at high RPMs (e.g., 13,300 RPM for a 115mm disc); the fiberglass reinforcement provides the necessary tensile strength to prevent the disc from shattering during operation. The EN12413 safety standard mandates specific requirements for this type of reinforcement.
What is an ultra-thin cutting disc?
Cutting discs with a thickness ranging from 1.0mm to 1.6mm are classified as ultra-thin. Stainless steel has poor thermal conductivity (only one-third that of carbon steel), meaning that cutting with thicker cutting discs causes heat buildup, leading to blue or black discoloration on the workpiece. Ultra-thin cutting discs offer a shorter contact arc and lower cutting resistance, resulting in faster cutting speeds that prevent heat accumulation. They produce a narrow kerf with minimal material loss and fewer burrs, often eliminating the need for subsequent grinding.
What is an INOX cutting disc?
“INOX” is the common European term for stainless steel. The defining characteristic of an INOX cutting disc is its high-purity formulation, which limits total impurities—specifically iron, sulfur, and chlorine—to below 0.1%. Standard cutting discs contain iron particles that can embed themselves into the stainless steel surface during cutting, leading to future rust formation and damage to the material’s protective passivation layer. Additionally, sulfur and chlorine can generate corrosive substances at high temperatures. INOX cutting discs eliminate these sources of contamination at the source, ensuring a bright, silvery-white cut and long-term corrosion resistance.
How Does an INOX Cutting Disc Work?
INOX cutting discs achieve material separation by using high-speed rotating abrasive grains to perform micro-cutting on the stainless steel surface. Unlike the shearing action of saw blades, the material removal process here relies on the interaction between the abrasive grains and the workpiece. When the INOX cutting disc operates at 10,000–13,000 RPM, zirconia alumina grains cut into the stainless steel surface at high linear speeds; each grain acts as a miniature cutting tool, shaving off tiny chips, while the continuous action of countless grains ultimately separates the workpiece.
The resin bond plays a crucial role in regulating the release rate of the abrasive grains. When the grains are sharp, the bond holds them firmly in place; as they become dull and cutting resistance increases, the bond releases the dulled grains under stress, exposing fresh, sharp grains underneath. This self-sharpening mechanism ensures consistent, high-efficiency cutting.
The ultra-thin design (1.0–1.6 mm) enhances efficiency in three ways:
Higher speed—The kerf width matches the disc thickness; a thinner disc removes less material and encounters less resistance, potentially increasing cutting speed by 30%.
Lower heat generation—Stainless steel has only one-third the thermal conductivity of carbon steel. The ultra-thin disc reduces the contact arc length and duration, preventing heat buildup; the cut remains silver-white, avoiding burn marks.
Fewer burrs—The thin disc exerts minimal lateral pressure on the workpiece, resulting in less material deformation and a smooth, clean cut, often eliminating the need for secondary deburring.
In summary: high-speed micro-cutting by zirconia alumina grains handles material removal, the resin bond’s self-sharpening regulation maintains sharpness, and the ultra-thin design minimizes resistance and heat accumulation—combining these factors to achieve fast, cool, and clean cutting results.
Why Choose an INOX Formula?
The corrosion resistance of stainless steel relies on a nanoscale chromium oxide passivation layer. Once this layer is compromised, the stainless steel loses its “stainless” capability. The core of the INOX formula lies in the absence of iron, sulfur, and chlorine—the three elements that pose the greatest threat to the passivation layer.
Iron-Free – Prevents Pitting Corrosion
Standard cutting discs contain iron particles. High cutting temperatures soften these particles, embedding them into the stainless steel surface and triggering galvanic corrosion with the base metal. The iron particles rust first; the resulting corrosion products directly attack the passivation layer, initiating pitting. Once pitting begins, rust spots spread, and the stainless steel’s corrosion resistance fails.
Sulfur-Free – Prevents Intergranular Corrosion
The resins or fillers in standard cutting discs may contain sulfur compounds. At high temperatures, sulfur is released and reacts with atmospheric moisture to form sulfurous and sulfuric acids. These acids attack along the metal’s grain boundaries, causing intergranular corrosion. While the surface may appear unaffected, the material’s internal structure is compromised, leading to a progressive decline in strength and toughness.
Chlorine-Free – Prevents Chloride Ions from Breaching the Passivation Layer
Chloride ions are the most dangerous destroyers of the passivation layer. High cutting temperatures release chloride ions (Cl⁻), which directly breach the passivation layer and create pitting craters on the surface. In applications such as food processing equipment, marine engineering, and chemical piping, chloride-induced pitting can escalate into crevice corrosion or even stress corrosion cracking (SCC).
What happens if you use standard cutting discs?
Contamination – Iron, sulfur, and chlorine transfer directly to the stainless steel surface at high temperatures; this is not merely a possibility, but an inevitability.
Corrosion – Rust attacks the passivation layer, sulfur generates corrosive acids, and chloride ions breach the protective film. Corrosion may not become visible for weeks or even months, making it impossible to trace the issue back to the source once the customer discovers it.
Impact on Welding – Contaminants from the cut surface enter the weld seam; sulfur causes hot cracking, while chlorine and iron oxides lead to porosity and slag inclusions, severely compromising weld quality.
Industry Standard: Leading brands such as DOME, Bosch, and DEWALT require INOX cutting discs to meet the specification of Fe + S + Cl ≤ 0.1%—a strict technical requirement ensuring stainless steel’s corrosion resistance, not merely a marketing claim.
Suitable Materials
Selecting a cutting disc depends on two key variables: the material type and the workpiece cross-section. Differences in hardness, thermal conductivity, and work-hardening tendencies among various stainless steel grades directly influence the choice of disc thickness and cutting parameters. Below are selection recommendations for common materials.
304 Stainless Steel
The most common grade of austenitic stainless steel, with a hardness of approximately 200–300 HB. Key cutting challenges include poor thermal conductivity and a tendency toward work hardening.
Recommended thickness: 1.0mm (thin sheets ≤3mm) / 1.2mm (general purpose) / 1.6mm (medium-thick plates 3–8mm)
Recommended specifications: 115mm × 1.0mm / 1.2mm × 22.23mm (angle grinder); 355mm × 2.5mm (stationary cut-off machine, for batch operations)
Selection logic: Use 1.0mm ultra-thin cutting discs for thin sheets to minimize heat buildup and prevent discoloration at the cut; use 1.2mm for general applications to balance cutting speed and durability; use 1.6mm for medium-thick plates to enhance impact resistance.
316 Stainless Steel
A molybdenum (Mo)-bearing austenitic stainless steel; it offers superior corrosion resistance compared to 304 but is harder and more difficult to cut.
Recommended thickness: 1.0mm (thin sheet ≤3mm) / 1.2mm (general purpose) / 1.6mm (medium-thick plate 3–8mm)
Recommended specifications: 115mm × 1.0mm / 1.2mm × 22.23mm (angle grinder); 355mm × 2.5mm (stationary cut-off machine)
Selection logic: Due to its higher hardness, 316 stainless steel causes more severe abrasive wear. It is recommended to prioritize discs specifically designed for stainless steel that feature zirconia alumina abrasive; a thin-disc design helps minimize contact time and control heat input.
430 Stainless Steel
A ferritic stainless steel containing chromium but no nickel; it is magnetic and offers lower corrosion resistance than austenitic grades, though it has relatively good machinability.
Recommended thickness: 1.2mm (general purpose) / 1.6mm (medium-gauge plate)
Recommended specifications: 115mm × 1.2mm × 22.23mm (angle grinder)
Selection rationale: 430 stainless steel contains no nickel and has a lower tendency for work hardening compared to 304 or 316 grades; a 1.2mm thickness is sufficient for most cutting applications. Cutting discs with an INOX-grade formulation must be used to prevent contamination from iron, sulfur, or chlorine.
Carbon Steel
Carbon steel offers good thermal conductivity and causes relatively mild abrasive wear on cutting discs, making it the easiest common metal to cut.
Recommended thickness: 1.2mm (thin sheets ≤3mm) / 1.6mm (general-purpose, most common) / 2.5mm (thick plates/solid stock ≥10mm)
Recommended specifications: 115mm × 1.6mm × 22.23mm (standard for angle grinders); 230mm × 2.5mm (high-power angle grinders, heavy-duty use)
Selection logic: Cutting carbon steel does not require extreme sharpness but demands good wear and heat resistance. The 1.6mm disc is the most versatile, balanced choice, offering a good compromise between cutting speed and durability.
Steel Tube
With a wall thickness typically ≤3mm, the primary concern during cutting is the deformation or flattening of the tube end.
Recommended thickness: 1.0mm / 1.2mm
Recommended specifications: 115mm × 1.0mm × 22.23mm (for angle grinders)
Selection rationale: Ultra-thin cutting discs are ideal for thin-walled tubes; they offer low cutting resistance and high speed, ensuring a smooth cut without deforming the tube end. The narrow kerf of the 1.0mm disc minimizes material loss, making it suitable for precision cutting.
Steel Pipe
Wall thickness is typically ≥5mm, requiring sufficient cutting depth and rigidity.
Recommended thickness: 1.6mm / 2.5mm
Recommended specifications: 180mm × 1.6mm × 22.23mm (for angle grinders); 355mm × 2.5mm / 3.0mm (for stationary cut-off machines; for large-diameter pipes)
Selection logic: Use standard 1.6mm or 2.5mm discs for thick-walled pipes to ensure rigidity and durability. For large-diameter pipes (DN100 and above), a large-diameter 355mm disc used with a stationary cut-off machine is recommended to enable a single-pass cut.
Angle Steel
Features an L-shaped cross-section with concentrated material at the corner, resulting in uneven cutting forces.
Recommended thicknesses: 1.2mm (light-duty, leg length ≤40mm) / 1.6mm (medium-duty) / 2.5mm (heavy-duty, leg length ≥50mm)
Recommended specifications: 115mm × 1.6mm × 22.23mm (standard for angle grinders); 230mm × 2.5mm (for large-sized angle steel)
Selection logic: Use thin discs for rapid cutting of light-duty angle steel; use thicker discs for heavy-duty angle steel to ensure greater impact resistance. It is recommended to initiate the cut at the sharp corner, cutting from the thinner section toward the thicker section to minimize impact.
Flat Bar
Features a rectangular cross-section and flat cut surfaces; it is one of the easiest profiles to cut.
Recommended thicknesses: 1.2mm (for material thickness ≤5mm) / 1.6mm (5–12mm) / 2.5mm (≥12mm)
Recommended specifications: 115mm × 1.6mm × 22.23mm (for standard angle grinders); 355mm × 2.5mm (for stationary cut-off machines/batch cutting)
Selection logic: Flat bars have a uniform cross-section, ensuring even cutting force. Use thin 1.2mm discs for thinner stock to increase cutting speed; use standard 2.5mm discs for thicker stock to ensure durability.

Stainless Steel Cutting Disc Series – Filter by Machine
Select the right disc based on the tool you are using – angle grinder or stationary cut-off machine.
Angle Grinder
Angle grinders are the most common tool for stainless steel cutting – ideal for flexible jobs, on‑site work, and small‑batch cutting. Choose the right disc based on your grinder size and power.
| Grinder Size | Recommended Disc Thickness | Recommended Series | Best For |
|---|---|---|---|
| 100mm / 105mm | 1.0mm / 1.2mm | Ultra Thin INOX | Precision cutting, tight spaces, DIY |
| 115mm / 125mm | 1.2mm / 1.6mm | Ultra Thin / Standard | Most versatile combination – covers most stainless cutting tasks |
| 180mm | 1.6mm | Heavy Duty INOX | Thick plates, large‑bore pipes, continuous operation |
| 230mm | 1.6mm / 2.0mm / 2.5mm | Heavy Duty INOX | Heavy hand‑held cutting, thick plate processing, solid bars |
Selection Logic:
- Small grinders (100–125mm) → Thin discs (1.0–1.2mm) → faster cutting, lower heat
- Large grinders (180–230mm) → Thicker discs (1.6–2.5mm) → greater rigidity, durability
- For hand‑held grinders, we do not recommend discs above 2.5mm – they become difficult and unsafe to handle.
Cut‑off Machine (Stationary)
Stationary cut‑off machines (chop saws) are used for high‑volume batch cutting, large structural sections, and thick‑wall pipes. The machine provides stable support, allowing larger diameters and thicker discs.
| Machine Type | Recommended Disc Spec | Recommended Series | Best For |
|---|---|---|---|
| Small chop saw | 300×2.5×25.4 | Large Diameter INOX | Medium pipes and sections – batch cutting |
| Standard chop saw | 355×2.5×25.4 | Large Diameter INOX | Most common size – covers most structural steel |
| Large chop saw | 355×3.0×25.4 | Large Diameter INOX | Heavy sections, large‑bore pipes, rails |
Selection Logic:
- Stationary equipment → allows thicker discs (2.5–3.0mm) → durability first
- Large diameter (355mm) → one‑pass through oversized sections → efficiency first
- Important: Large‑diameter discs are for stationary saws only – never mount them on hand‑held angle grinders.

Technical Notes:
Disc thickness directly affects cutting speed, heat generation, durability, and safety. The relationship between thickness and application is governed by three physical principles:
- Thin discs (0.8–1.0mm) → short contact arc, fast penetration, low heat → ideal for sheet metal (≤3mm) – clean, discolouration‑free cuts with minimal burrs
- Medium‑thickness discs (1.2–1.6mm) → balanced speed and durability → ideal for general cutting (3–15mm) – covers over 80% of daily fabrication tasks
- Thick discs (2.0–3.0mm) → high rigidity, impact resistance, long life → ideal for thick plates (≥15mm), solid bars, and large structural sections
Core logic: the thicker the workpiece, the thicker the disc. Thin discs on thick materials risk breakage; thick discs on thin materials generate excessive heat and wide kerfs. For hand‑held angle grinders, thickness should not exceed 2.5mm; stationary cut‑off machines can use 2.5–3.0mm discs, prioritising durability and service life.
Stainless Steel Cutting Disc Features
Fast Cutting
Utilizes zirconia alumina abrasive with micro-fracturing properties; new, sharp cutting edges are continuously exposed during use, preventing dulling and slippage. The ultra-thin design (0.8–1.2 mm) minimizes cutting resistance, increasing cutting speed by up to 30% compared to standard discs. Suitable for 304/316/430 stainless steel and carbon steel.
Minimal Burrs
The narrow kerf (0.8–1.0 mm) exerts minimal lateral pressure on the workpiece, allowing sharp abrasives to cut smoothly without causing edge deformation. The cut surface is flat and smooth, often eliminating the need for subsequent grinding or deburring. This is particularly suitable for industries requiring high surface quality, such as food processing equipment, kitchenware, and medical devices.
Stable Performance
Each disc undergoes precision dynamic balancing to eliminate mass imbalance, while multi-layer fiberglass mesh provides a damping effect that absorbs high-frequency vibrations. Automated manufacturing processes ensure the uniform distribution of abrasives and resin, delivering consistent performance—without degradation—from the first cut to the last.
Long Service Life
Zirconia alumina abrasives offer superior wear resistance, while the bond hardness is precisely controlled—neither too hard (preventing dull grains from shedding) nor too soft (preventing premature detachment). Abrasive grains are fully utilized before shedding, ensuring no waste. Less frequent disc changes reduce downtime and result in better overall cost-efficiency.
Safe Operation
Triple-layer safety assurance: EN12413 certification (comprehensive testing for burst resistance and lateral load capacity), multi-layer fiberglass reinforcement (resistance to centrifugal tearing), and 100% rotational speed testing (individual verification for every disc). The maximum rotational speed is clearly marked; verify that the equipment’s speed does not exceed the rated value before use.
Stainless Steel Cutting Disc Applications
Stainless Steel Pipe
Stainless steel pipes are widely used in the chemical, food, pharmaceutical and construction industries. The primary challenge in cutting these pipes lies in their circular cross-section, which is difficult to secure; they tend to roll, leading to skewed cuts. When the pipe is properly clamped and cut using an ultra-thin (1.0–1.2 mm) INOX disc with a steady, uniform feed rate, the resulting cut is clean and smooth, free from deformation or burn marks. DOME discs utilize zirconia-alumina abrasive and a high-purity formulation to eliminate iron particle contamination.
Stainless Steel Tube
Stainless steel thin-walled tubes (wall thickness ≤ 3mm) are used for handrails, exhaust pipes and heat exchangers. Due to the low rigidity of the tube walls, traditional cutting methods often cause crushing or deformation. Ultra-thin 1.0mm stainless steel cutting discs feature a narrow kerf and exert minimal lateral pressure during entry, ensuring the tube end retains its circular shape without flattening. When used with a high-speed angle grinder and light feed pressure, they deliver fast cutting and low heat generation, producing smooth, burr-free edges that require no secondary finishing.
Stainless Steel Sheet
Thin stainless steel sheets (≤3mm) are used in kitchenware, decorative applications, and sheet metal fabrication. Two major challenges arise: discoloration (turning blue or black) at the cut edge and thermal deformation of the material. For ultra-thin sheets (0.8–1.0mm), the contact arc length is reduced, resulting in shorter cutting times and minimal heat generation; consequently, the cut edge retains its natural silvery-white finish. Lateral pressure is low, preventing sheet warping. The cut edges are smooth with minimal burrs, allowing for direct bending or welding in most cases.
Kitchen Equipment
Commercial kitchen equipment—such as countertops, range hoods, and refrigerator panels—is constructed entirely from 304 stainless steel. Surface quality requirements are extremely stringent, as scratches, burn marks, and burrs can compromise the product’s appearance. Furthermore, embedded iron particles can lead to future rusting, posing a risk to food safety. The INOX sheet features a high-purity formulation (Fe+S+Cl ≤ 0.1%) that eliminates the risk of particle embedding. The cut edges remain bright and silvery, ensuring the product’s aesthetic appeal and durability while safeguarding food safety.
Food Machinery
Food processing machinery—such as mixing tanks, conveyor belts, and filling equipment—demands higher standards than standard kitchen equipment: cutting surfaces must be absolutely smooth and free of contamination, as any residual iron particles or surface pits can harbor bacteria. Since welding follows immediately after cutting, there is no opportunity for remedial grinding. DOME INOX sheets deliver a finished edge in a single step—smooth, burr-free, burn-free, and uncontaminated—fully meeting food-grade hygiene standards.
Petrochemical
In the petrochemical industry—spanning offshore platforms and oil refineries—stainless steel piping is frequently exposed to acidic, saline, and high-temperature environments. Iron or chlorine residues left on cut surfaces can serve as initiation points for stress corrosion cracking; standard cutting discs contain iron and chlorine, and the resulting residues trigger localized corrosion in chemical environments, ultimately leading to leaks. DOME INOX discs are free of iron, sulfur, and chlorine; they are EN12413 certified and undergo 100% rotational speed testing, ensuring safety for high-risk operations.
Shipbuilding
In shipyards, the cutting of stainless steel piping and deck fittings often takes place in environments with high salt-spray exposure; iron particle contamination serves as a starting point for future pitting corrosion. Given the confined spaces, thick materials, and high cutting volumes involved, high-power angle grinders are frequently required for prolonged, continuous operation. These INOX discs feature a high-purity formulation (Fe+S+Cl ≤ 0.1%) that eliminates the risk of rust caused by embedded iron particles, while the thin-disc design minimizes heat buildup and prevents discoloration.
Structural Steel
Large stainless steel structural sections—such as H-beams and I-beams—are used in architectural curtain wall frameworks and bridges. Due to their large cross-sections and thick flanges, they cannot be cut through in a single pass using a handheld angle grinder. When paired with a stationary cutting machine, a 355mm large-diameter stainless steel cutting disc (2.5–3.0mm thick) allows for a clean, perpendicular cut through these large sections in one go, eliminating the need to flip the workpiece or perform secondary cuts. Featuring multi-layer fiberglass reinforcement for high impact resistance, this disc is the ideal choice for heavy-duty, high-volume cutting operations.
How to Choose the Right Disc
Step 1: What material are you cutting?
| Material | Abrasive Type | Notes |
|---|---|---|
| 304 Stainless Steel | Zirconia Alumina | Most common grade – kitchenware, piping, decoration |
| 316 Stainless Steel | Zirconia Alumina | Molybdenum‑added, higher corrosion resistance – marine/medical |
| 430 Stainless Steel | Zirconia Alumina | Ferritic grade – lower work‑hardening tendency |
→ All use INOX‑specific discs (zirconia alumina, Fe+S+Cl ≤0.1%)
Step 2: How thick is your material?
| Material Thickness | Recommended Disc Thickness | Product Series |
|---|---|---|
| Sheet / thin‑wall tube (≤3mm) | 1.0mm | Ultra Thin Stainless Steel |
| Medium plate / tube (3–8mm) | 1.2mm | Standard Stainless Steel |
| Thick plate / heavy‑wall tube (8–15mm) | 1.6mm | Heavy Duty Stainless Steel |
| Solid bar / large sections (≥15mm) | 3.0mm | Heavy Duty / Large Diameter |
Step 3: What tool are you using?
| Your Tool | Recommended Diameter | Recommended Thickness | Series |
|---|---|---|---|
| 100–125mm angle grinder | 100–125mm | 1.0–1.2mm | Ultra Thin / Standard |
| 180–230mm angle grinder | 180–230mm | 1.6–3.0mm | Heavy Duty |
| Stationary cut‑off saw | 300–355mm | 3.0–4.0mm | Large Diameter |
Step 4: Your recommended disc specification
| Your Combination | Recommended Spec |
|---|---|
| 304 sheet (≤3mm) + 115mm grinder | 115×1.0×22.23mm |
| 304 medium plate (3–8mm) + 115mm grinder | 115×1.2×22.23mm |
| 316 stainless + 125mm grinder | 125×1.2×22.23mm |
| Thick plate (8–15mm) + 230mm high‑power grinder | 230×1.6×22.23mm |
| Solid bar (≥15mm) + 230mm grinder | 230×3.0×22.23mm |
| Large structural sections + stationary saw | 355×3.0×25.4mm |
| Large‑bore heavy‑wall pipe + stationary saw | 355×4.0×25.4mm |
INOX Disc vs Standard Metal Disc
| Criteria | Stainless Steel Cutting Disc | Standard Metal Cutting Disc |
|---|---|---|
| Cutting Speed | Fast (ultra‑thin design, low resistance) | Slower (thicker, higher friction) |
| Heat Generation | Low (short contact time, heat dissipates quickly) | High (thick disc, poor thermal conductivity of stainless) |
| Burrs | Minimal – often no deburring needed | More burrs – requires deburring |
| Contamination Risk | None (Fe+S+Cl ≤0.1%) | High (contains iron, sulphur, chlorine – transfers to workpiece at high temperatures) |
| Service Life | Longer (zirconia alumina is highly wear‑resistant) | Moderate (brown fused alumina wears faster on stainless) |
| Recommended Materials | Stainless steel (304/316/430), carbon steel | Carbon steel, structural steel (not suitable for stainless) |
| Safety | High (EN12413 + 100% RPM tested) | General (basic safety standards) |
When to Use Standard Metal Disc?
For cutting carbon steel and general structural steel – carbon steel has good thermal conductivity and causes mild abrasive wear; brown fused alumina discs offer the best cost‑performance. For rough cutting on non‑critical surfaces – where cut quality and contamination are not a concern.
Rule of thumb: Standard discs are for carbon steel only. Using them on stainless is not just “less effective” – it contaminates the material.
When Must You Use a Stainless Steel Cutting Disc?
When cutting any stainless steel – standard discs contain iron, sulphur, and chlorine. At cutting temperatures, these contaminants transfer to the stainless surface, causing iron embedment (leading to rust), sulphur/chlorine attack on the passive layer, and blue/black discolouration.
For food equipment, medical devices, and pharmaceutical machinery – contaminants become breeding grounds for bacteria; only Fe+S+Cl ≤0.1% pure formulations are acceptable.
For marine engineering and shipbuilding – in constant salt‑spray environments, iron contamination is the starting point for corrosion.
When surface quality matters – Stainless steel cutting discs deliver silver‑bright, burn‑free, burr‑free cuts, eliminating secondary finishing.
Manufacturing Process
1. Raw Material Inspection
Abrasives, resins, and fiberglass mesh are tested in every batch upon arrival at the factory. Abrasives with incorrect particle size are returned immediately, resins with substandard viscosity are not used, and fiberglass meshes with insufficient tensile strength are not released. Raw material inspection data is recorded, making each batch traceable. If the source is wrong, everything else is wasted.
2. Mixing
The qualified raw materials are accurately weighed according to the formula and put into a closed mixing system. Zirconia-alumina abrasive, resin binder, and INOX additives are thoroughly mixed. If the proportion deviation exceeds the set range, the entire batch is discarded. The uniformity of the mixture directly determines the consistency of the cutting force of the cutting disc—this is non-negotiable.
3. Pressing
The mixture is fed into a press and formed under high pressure. During pressing, fiberglass mesh is embedded in the abrasive layers, forming a reinforcing skeleton. There are tolerances for both pressure and thickness; anything exceeding these tolerances is scrapped. The resulting blank has the shape of a slit, but it is still very fragile at this stage.
4. Curing
The preform enters the curing oven and is heated for tens of hours according to the set temperature profile. The resin undergoes a cross-linking reaction at high temperature, changing from a liquid state to a solid state through thermal curing, firmly fixing the abrasive particles. Too high or too low a temperature will cause problems, so DOME uses a programmed temperature control system to lock the curing conditions for each batch, keeping the fluctuations between batches within a very small range.
5. Balancing
Each cutting disc is tested by a dynamic balancing machine. Cutting discs with excessive eccentricity cannot pass the test—when such discs are mounted on an angle grinder, the entire machine vibrates, and the cut lines are crooked. DOME’s balancing standards are stricter than industry-standard requirements, and large-diameter discs undergo two more tests.
6. Burst Test
Random samples are taken from each batch, and the machine is accelerated from zero to fracture speed, recording the fracture speed. EN12413 standard stipulates that the fracture speed must not be less than 1.5 times the rated maximum speed. DOME’s internal standard is even higher than this. If the data fails to meet the requirements, the entire batch will not be shipped—without exception.
7. Packaging
After all tests are passed, each piece is individually packaged to prevent moisture damage during transportation and storage. The label must include all specifications, aperture, maximum speed, and EN12413 markings. The outer carton must have complete batch information. DOME performs random inspections on each carton – incorrect labeling or damaged packaging results in the entire carton being reworked.
8. Shipment
Finished products are categorized and stored according to orders, ready for shipment. Each batch of goods is accompanied by a Certificate of Analysis (COA), covering data such as dimensional accuracy, dynamic balance, and burst testing for that batch. From raw material intake to finished product shipment, every piece can be traced back to its specific batch and testing records. The buyer receives not only cutting discs, but also traceability of the entire supply chain.
Quality Control
Before every disc leaves the factory, it must pass six inspection checkpoints. Each checkpoint has clear, measurable standards.
1. Dimensional Accuracy Inspection
The outer diameter, thickness, and aperture of each cutting disc must be measured. If the outer diameter is too large, it won’t fit into the machine; if it’s too small, it will wobble after installation. A thickness deviation exceeding 0.1mm will result in inconsistent kerf widths. An unqualified aperture will prevent the disc from being installed at all. DOME uses high-precision measuring instruments to inspect each disc individually, and any discs exceeding the dimensional tolerances are rejected.
2. Appearance inspection
Visually inspect, touch, and listen to the sound when tapped. Surface cracks, bubbles, missing corners, and uneven coloring result in immediate rejection. The tapping test is an industry-standard method—a good cutting disc produces a crisp sound when tapped, while one with internal cracks produces a dull sound. While appearance defects may seem minor, any micro-defect can become a fracture point during high-speed rotation.
3. Hardness testing
Hardness measurement doesn’t measure the material’s hardness, but rather the binding force of the resin binder on the abrasive grains. A hardness tester is used to mark points on the cutting disc’s surface; the reading must be within the standard range. Too high a hardness means the abrasive grains become dull and won’t fall off, resulting in slower cutting and increased heat. Too low a hardness means the abrasive grains fall off before being fully worn away, leading to a shorter lifespan. If the hardness fails to meet the standard, the entire batch is returned.
4. Dynamic balancing test
If the cutting disc is misaligned during high-speed rotation, it will generate centrifugal force, causing vibration. DOME tests each cutting disc with a dynamic balancing machine; any disc that is misaligned is immediately scrapped. This is especially true for the 355mm large-diameter discs, where the balancing requirements are much stricter than for smaller discs. If a disc that is not properly balanced is mounted on an angle grinder, the entire machine will vibrate, resulting in crooked cuts.
5. Rupture test
This is the most critical test in the safety process. Random samples are taken from each batch and tested on a testing machine, gradually accelerated from a standstill to 1.5 times the calibrated maximum speed, continuously verifying structural integrity. The EN12413 standard requires a fracture speed ≥ 1.5 times the rated maximum speed. DOME’s internal standards are even stricter than EN12413. Any abnormality during testing results in the entire batch being rejected.
6. Cutting performance test
Sample cutting discs are mounted on an angle grinder to cut standard test pieces (such as 12mm stainless steel bars), and the cutting speed and number of cuts are recorded. Cutting speed reflects the sharpness of the abrasive, while the number of cuts reflects its lifespan. DOME conducts tests on various materials—stainless steel, carbon steel, etc.—to ensure consistent performance of each batch of products under different operating conditions. If the data fails to meet standards, the entire batch is reworked.

Stainless Steel Cutting Disc FAQ
1. What is the difference between an INOX disc and a regular cutting disc?
A regular cutting disc contains iron, sulphur, and chlorine – elements that contaminate stainless steel surfaces during cutting. Contamination leads to rust, pitting, and loss of corrosion resistance. An INOX disc is formulated with Fe+S+Cl ≤0.1%, ensuring no contaminants transfer to the workpiece. The cut stays silver-bright and the material’s anti-corrosion properties remain intact.
2. Can I use an INOX disc on carbon steel?
Yes, but it’s not cost‑effective. An INOX disc uses premium zirconia alumina abrasives designed for stainless steel’s toughness. On carbon steel, where heat conductivity is good and wear is mild, a standard brown fused alumina disc delivers similar cutting speed at a lower cost. If you do cut carbon steel with an INOX disc, never use that same disc on stainless afterwards – cross‑contamination will occur.
3. What do T41 and T42 mean on a cutting disc?
T41 and T42 are European standard shape designations. T41 (Type 1) is a flat disc with no recess – used for straight cutting on angle grinders and chop saws. T42 (Type 27) has a depressed centre – the recess provides clearance for cutting in corners and allows a better cutting angle in deep cuts. Both are available for stainless steel applications.
4. Can I cut stainless steel with a standard metal cutting disc?
Theoretically yes, but you absolutely should not. Standard discs contain iron, sulphur, and chlorine – these contaminants transfer to the stainless surface during cutting. The result is rust, pitting, and loss of corrosion resistance. The cut will also show blue/black discolouration from excessive heat. Using a standard disc on stainless is not just poor practice – it damages the material’s long‑term integrity.
5. What thickness disc should I use for thin stainless sheet?
For stainless sheet up to 3mm, use 1.0–1.2mm ultra‑thin discs. Thin sheets have low thermal mass – heat builds up quickly and causes blue discolouration and warping. A thin disc cuts fast with minimal heat, keeps the cut silver‑bright, and produces clean, burr‑free edges. For sheet metal fabrication, thinner is almost always better.
6. Can I cut stainless steel pipe with a 115mm angle grinder?
Yes, for pipes up to about 35mm diameter. Use a 1.0mm or 1.2mm INOX disc and ensure the pipe is securely clamped – round sections roll and cause crooked cuts. Cut with steady, moderate pressure and let the disc do the work. For larger diameter pipes, use a 355mm disc on a stationary chop saw for a single‑pass cut.
7. Can a stainless steel cutting disc be used for bevel cutting?
Yes, stainless steel cutting discs can cut at angles. The abrasive nature of the disc allows cutting at different angles, which is exactly what bevel cutting requires. However, avoid side pressure during bevel cuts – cutting discs are designed for edge cutting, not grinding. For consistent bevel angles, use a stationary chop saw with an angle adjustment feature.
8. Do you provide private label packaging for cutting discs?
Yes – we offer complete private label packaging solutions. This includes custom printed labels with your logo and branding, custom inner and outer packaging, shrink‑wrap with your design, and custom carton printing. All packaging is designed to protect the discs during transit and storage while presenting your brand professionally. We can also match your existing packaging specifications for consistency.
9. Can I order a custom thickness or diameter not in your standard range?
Yes, we manufacture custom sizes beyond our standard range. Standard diameters include 100mm, 115mm, 125mm, 180mm, 230mm, and 355mm. If you need a different diameter or a non‑standard thickness, we can tool up for your specification. Minimum order quantity may be higher for non‑standard sizes. Contact us with your requirements and we’ll confirm feasibility and lead time.
10. What safety standards do your cutting discs meet?
All DOME discs meet EN12413 – the mandatory European safety standard for bonded abrasives. EN12413 covers burst strength, side load capacity, permissible unbalance, and marking requirements. MPA (German Materials Testing Institute) certification provides additional safety verification for European markets. Every disc is 100% RPM tested individually before leaving the factory.
11. Do you test every disc or just batch sample?
We test every single disc for dimensional accuracy, thickness tolerance, bore size, and dynamic balance. For burst testing and cutting performance, we use batch sampling – but every disc is individually RPM tested at 150% of rated speed. This ensures that if there’s a structural defect, it’s caught before the disc reaches the customer.
12. How long do stainless steel cutting discs last?
Service life depends on material thickness, cutting frequency, and operator technique. On 3mm stainless sheet, a 1.0mm disc typically lasts 50–100 cuts. On thicker materials, life is shorter – but zirconia alumina abrasives extend life compared to standard aluminium oxide. The best indicator is visual wear – replace the disc when it approaches the flange. Overused discs are unsafe and cut poorly.
13. How are cutting discs packed for shipping?
Each disc is individually shrink‑wrapped to protect against moisture during transit and storage. Discs are then packed in sturdy export cartons with proper cushioning. Cartons are palletised and stretch‑wrapped for container shipping. For OEM orders, we can match your specific packaging requirements. All packaging is designed to ensure discs arrive in perfect condition – no cracks, no moisture damage.
14. What is the minimum order quantity for a wholesale order?
Minimum order quantity depends on the product type and whether it’s a standard or custom order. For standard products, MOQ is flexible – we work with both small and large distributors. For OEM custom orders with private label packaging, MOQ is higher but negotiable based on your order volume. Contact us with your requirements and we’ll provide a specific quote.
15. Do you offer samples before placing a bulk order?
Yes – we provide free samples for testing before you commit to a bulk order. Samples are sent with full specifications and test data. We recommend testing the disc on your actual material and equipment to confirm cutting speed, life, and cut quality match your requirements. Once you’re satisfied, we proceed with production.
