What Are Cutting Wheels?
A cutting wheel—also known as an abrasive cutting wheel or cut-off wheel—is a thin, consumable disc designed to slice through metal and other hard materials using high-speed friction. Unlike a saw blade that cuts with teeth, a cutting wheel removes material through abrasion: thousands of sharp abrasive grains on the wheel’s surface grind away tiny chips of metal with each rotation.
How Cutting Wheels Are Made
A resin bonded cutting disc is a composite structure. It starts with abrasive grain—typically aluminum oxide for general steel, zirconia alumina for stainless steel and tough alloys, or ceramic alumina for extreme applications. These grains are bonded together by a resin binder (usually phenolic resin), which holds the abrasive particles firmly in place while allowing worn grains to break away and expose fresh, sharp cutting edges beneath. To withstand the immense centrifugal forces of high-speed rotation, the disc is reinforced with layers of fiberglass mesh, preventing it from shattering during operation.
Types of Cutting Wheels
Cutting wheels can be categorized by material, size, and machine type. Understanding these classifications can help you quickly find the right product for your specific needs.
By Material
Metal Cutting Wheel
Designed for carbon steel, cast iron, and general structural steel. Typically uses brown fused alumina abrasive for cost‑effective, fast cutting. Thickness ranges from 1.0mm to 3.0mm – thin discs for sheet and tube, thick discs for solid bars and heavy‑duty jobs.
Stainless Steel Cutting Disc
Engineered specifically for austenitic stainless steels like 304 and 316. Uses zirconia alumina abrasive with a low‑iron pure formulation (Fe+S+Cl ≤0.1%) to prevent iron embedment and subsequent rust. Delivers silver‑bright, burn‑free cuts without workpiece contamination.
Aluminum Cutting Wheel
Designed for soft non‑ferrous metals like aluminum and copper. The main challenge is clogging – soft metals tend to load the abrasive. These discs use special additives and a more open structure to reduce loading and maintain cutting efficiency.
Stone Cutting Disc
Used for cutting concrete, brick, stone, and other hard brittle materials. Typically uses silicon carbide abrasive, which is hard and sharp. Note: stone cutting discs are not suitable for metal cutting, and vice versa.
By Size
Mini Cutting Disc
Diameter up to 3 inches (76mm) for small pneumatic or electric die grinders. Ideal for precision cutting, model making, and tight spaces. Thickness usually 0.8–1.0mm with very high RPM ratings (up to 20,000 RPM).
4 inch Cutting Wheel
100/105/107mm diameter, fits 4‑inch angle grinders. Suitable for DIY, home repairs, and light precision cutting. Cut depth approximately 30mm – lightweight and easy to handle, popular among entry‑level users.
4.5 inch Cutting Disc
115mm diameter – the most widely used size globally. Fits 4.5‑inch angle grinders with a cut depth of about 35mm. Covers most daily cutting tasks from sheet metal to medium profiles. Thickness options from 0.8mm to 3.0mm offer maximum versatility.
9 inch Cutting Wheel
230mm diameter – the largest size for hand‑held angle grinders. Designed for 9‑inch high‑power grinders (2000W+), delivering approximately 75mm cut depth. Perfect for construction sites, thick plate cutting, and heavy repair work.
14 inch Cutting Disc
355mm diameter – exclusively for stationary chop saws. Max cut depth about 120mm – cuts through large H‑beams, I‑beams, and large‑diameter heavy‑wall pipes in a single pass. Thickness 2.5–3.0mm prioritises durability and safety.
By Machine
Angle Grinder Cutting Disc
Diameters 100–230mm, fits hand‑held angle grinders. Characterised by portability and flexibility – ideal for on‑site work, maintenance, and small‑batch cutting. Thickness ranges 0.8–3.0mm for versatile material thickness adaptation.

We produce thin cutting discs, standard cutting discs, and all popular sizes – including 115mm cutting discs for angle grinders, 125mm cutting discs, 230mm cutting discs, and 9‑inch cutting wheels for both hand‑held and stationary machines.
Metal Cutting Wheel
Carbon Steel · Structural Steel · General Steel · Everyday Cutting
Metal cutting wheels are designed for carbon steel, structural steel, cast iron, and other ferrous metals. They use brown fused alumina abrasive – cost‑effective and fast‑cutting. Thin discs (1.0–1.2mm) are ideal for sheet and tube – fast cutting with minimal burrs. Thick discs (2.5–3.0mm) suit solid bars and heavy‑duty work – durable and impact‑resistant. Widely used in steel fabrication, construction, machinery manufacturing, and pipe installation – one inventory covering most daily workshop needs.
Stainless Steel Cutting Disc
304 · 316 · INOX · Low Heat · Low Burr
Stainless steel cutting discs are engineered for 304 and 316 stainless steel. They use zirconia alumina abrasive that continuously self‑sharpens during cutting, exposing fresh cutting edges. The Fe+S+Cl ≤0.1% pure formulation prevents iron embedment on the surface, eliminating future rust risks. The ultra‑thin profile shortens contact time, preventing heat build‑up – delivering silver‑bright, burn‑free, burr‑free cuts that require no secondary finishing. Ideal for stainless steel sheet, tubes, kitchen equipment, food machinery, and other high‑surface‑quality applications.
Aluminum Cutting Disc
Non‑Loading Formula · Soft Metal · Smooth Cutting · No Clogging
Aluminum cutting discs are specially designed for soft non‑ferrous metals like aluminum and copper. The main challenge with soft metals is clogging – aluminum’s high adhesion fills abrasive grains, rendering the disc ineffective. These discs incorporate special lubricants and anti‑loading additives, combined with a more open wheel structure to facilitate chip clearance – ensuring smooth, clog‑free cutting. Suitable for aluminum profiles, sheets, copper tubes, and more. Widely used in window/door manufacturing, electrical engineering, and HVAC.
Stone Cutting Disc
Silicon Carbide · Hard Brittle Materials · Concrete Cutting · Masonry Specific
Stone cutting discs are designed for concrete, brick, stone, tiles, and other hard brittle materials. They use silicon carbide abrasive – extremely hard and sharp. Do not use for metal cutting, and vice versa. RPM ratings are typically lower than for metal discs – always check tool compatibility before use. Widely used in construction, renovation, road maintenance, and tile laying.

Thickness Selection Guide:
- 1.0–1.2mm (Ultra Thin) – Fastest cutting, lowest heat, minimal burrs. Ideal for sheet metal (≤3mm) and thin‑wall tubes.
- 1.6mm (Standard) – Best balance of speed and durability. Covers 80% of daily cutting tasks – plates (3–8mm), pipes, and profiles.
- 2.5–3.0mm (Heavy Duty) – Greater rigidity and impact resistance. For thick plates (≥8mm), solid bars, and heavy structural sections.
- 3.0–4.0mm (Large Diameter) – Maximum durability. For stationary chop saws – large beams, heavy‑wall pipes, and rails.
Grit Size Selection Guide:
- Coarse (16–24#) – Fast material removal, rough finish. Best for heavy cutting and thick sections.
- Medium (30–46#) – The most versatile range. Good cutting speed with acceptable finish – covers most general fabrication work.
- Fine (60–80#) – Slower cutting, smoother finish. Best for precision work and thin materials where surface quality matters.
EN12413 Safety Standard:
EN12413 is the mandatory European safety standard for bonded abrasive products. It requires that the actual burst speed of a cutting disc must be at least 1.5× the rated maximum RPM. All DOME discs are EN12413 certified, with MPA (German Materials Testing Institute) certification available for European markets. Every disc is 100% RPM tested individually before leaving the factory.
Cutting Wheel Buying Guide
Choosing the right cutting wheel can save time, reduce waste, and keep you safe. With so many options on the market, you only need to check three things: the material you cut, the thickness you need, and the machine you use. Let’s break it down.
1. Match the Cutting Wheel to Your Material
Different materials require different abrasive grains and bonds. Using the wrong cutting disc leads to poor performance, overheating, or even breakage.
- Carbon steel – Use a standard aluminum oxide cutting wheel. It cuts cleanly and resists wear on tough steel.
- Stainless steel – Choose a stainless steel cutting disc made with zirconia or ceramic grain. It cuts faster and generates less heat, preventing blue discoloration.
- Aluminum – Pick a cutting wheel for aluminum with a non‑loading additive. Soft aluminum tends to clog standard wheels, so this special type stays sharp and open.
- Stone – Use a silicon carbide cutting wheel designed for masonry. These handle abrasive, brittle materials without chipping.
2. Choose the Right Thickness – Thin vs. Standard
Thickness affects cut speed, accuracy, and strength.
- Thin cutting disc (1.0 – 1.6 mm) – Ideal for fast, precise cuts with minimal material loss. They produce less dust, reduce sparking, and put less strain on your grinder. Perfect for sheet metal, pipes, and thin profiles.
- Standard cutting disc (2.0 – 3.0 mm) – Heavier and more durable. Use them for thicker sections, structural steel, or when you need extra side stability. They last longer but remove more material per cut.
Simple rule: Use a thin cutting disc for speed and finish; use a standard cutting disc for strength and heavy‑duty work.
3. Consider Your Application – Angle Grinder or Stationary Machine?
Your cutting tool determines the disc’s arbor size, maximum RPM, and overall design.
- Angle grinder – This is the most common machine. Most cutting wheels for angle grinders come in popular sizes like 115mm, 125mm, or 230mm (9 inch). Always check the RPM rating on the disc matches your grinder’s speed. For handheld use, thin cutting discs are especially popular because they reduce vibration and fatigue.
- Stationary machine (e.g., chop saw, cut‑off saw) – These use larger cutting wheels (often 14 inches or more) with reinforced cores. They provide stable, straight cuts for repetitive production work. For these machines, standard cutting discs are more common due to the higher torque and continuous operation.
How to Choose Cutting Wheel Thickness
Disc thickness determines cutting speed, heat generation, durability, and safety. Pick the wrong thickness and you get poor performance, bad cuts, and even safety risks. Here’s how to choose between the three most common thicknesses.
1.0mm – Ultra‑Thin High‑Speed
Best for: Sheet metal (≤3mm), thin‑wall tubes, precision cutting
1.0mm is the mainstream ultra‑thin size. A narrow kerf shortens contact time – heat doesn’t have time to build up, so the cut stays silver‑bright. Less material removal means lower cutting resistance and faster feed. Minimal side pressure means few burrs – often no deburring needed. Ideal for stainless steel sheet, kitchen panels, and sheet metal fabrication where cut quality matters.
In short: Thin sheets cut fast, stay bright, and need no edge finishing.
1.6mm – All‑Purpose Balanced
Best for: General fabrication, medium plates (3–15mm), structural sections
1.6mm is the sweet spot for everyday cutting – more durable than 1.0mm, faster than 2.5mm. It covers over 80% of daily workshop tasks. The extra thickness gives longer life and greater rigidity, so cuts on angle iron and channels stay straight with less deflection.
In short: If you buy only one thickness, 1.6mm is your safest bet.
3.0mm – Heavy‑Duty Durable
Best for: Thick plates (≥15mm), solid bars, large structural sections – stationary saws only
3.0mm is designed exclusively for stationary chop saws. Triple the thickness of 1.0mm means much more usable volume – more cuts per disc. High rigidity handles heavy feed pressure and side impacts. Larger thermal mass resists overheating during continuous operation. Not recommended for hand‑held angle grinders – too much resistance, hard to control, and unsafe.
In short: For thick stock and high‑volume cutting, 3.0mm is the workhorse.
How to Choose Cutting Disc Diameter
The diameter of a cutting disc determines three things: what tool it fits, how deep it cuts, and what applications it suits. Pick the wrong diameter, and you either can’t mount it, can’t cut deep enough, or create a serious safety hazard.
115mm – All‑Purpose Hand‑Held
Best for: 4.5″ angle grinders · everyday cutting · general maintenance
115mm (4.5″) is the world’s most popular cutting disc size. It fits standard 4.5‑inch angle grinders (700–1000W) and delivers a cut depth of about 35mm – covering everything from sheet metal to medium profiles. Lightweight and easy to handle with one hand, it’s the go‑to size for construction sites, pipe fitting, steel fabrication, and daily repair work. If you only buy one size, 115mm is the safest choice.
In short: The sweet spot for hand‑held cutting – versatile, easy to find, and gets most jobs done.
230mm – High‑Power Hand‑Held
Best for: 9″ angle grinders · heavy hand‑held cutting · thick plate processing
230mm (9″) is the largest size that fits a hand‑held angle grinder. It runs on 9‑inch high‑power grinders (2000W+) and delivers a cut depth of approximately 75mm – more than double that of 115mm. Ideal for thick plates, large‑diameter pipes, solid bars, and heavy construction site work. The tool is bulky and requires two‑handed operation, but for on‑site jobs where a stationary saw isn’t available, 230mm offers the maximum cutting capacity you can get from a hand‑held machine.
In short: The top end of hand‑held cutting – deep cuts and plenty of power, but heavy and needs both hands.
355mm – Stationary Saw Only
Best for: Chop saws · high‑volume batch cutting · large structural sections
355mm (14″) is the standard size for stationary cut‑off saws (chop saws). Cut depth is about 120mm – enough to cut through large H‑beams, I‑beams, heavy‑wall pipes, and standard rails in one pass. The machine provides stable support and guided feed, ensuring square, straight cuts with high angle precision. Disc thickness is typically 2.5–3.0mm for durability during continuous batch work. Never mount a 355mm disc on a hand‑held angle grinder – it’s too large, and if it shatters, the consequences are severe.
In short: The workhorse for stationary saws – deepest cuts, straightest results, and safest (when used on the right machine).
Diameter vs. Cut Depth Reference
| Diameter | Common Name | Tool Fit | Max Cut Depth | Typical Use |
|---|---|---|---|---|
| 115mm | 4.5″ | 4.5″ angle grinder | ~35mm | Everyday general cutting |
| 125mm | 5″ | 5″ angle grinder | ~40mm | Mainstream in North America |
| 180mm | 7″ | 7″ high‑power grinder | ~60mm | Heavy hand‑held cutting |
| 230mm | 9″ | 9″ high‑power grinder | ~7mm | Maximum hand‑held capacity |
| 355mm | 14″ | Stationary chop saw | ~120mm | Batch cutting, large sections |
Selection Logic – Simple Rule
Start with your tool, then consider your needs:
- 4.5″ angle grinder → 115mm (most versatile – handles 90% of jobs)
- 7–9″ angle grinder → 180–230mm (heavy hand‑held work, construction sites)
- Stationary saw → 355mm (batch cutting, large structural steel)
In short: match the diameter to your tool. If you need more cut depth, get a bigger tool and a bigger disc. Never fit a 355mm disc on a 230mm grinder, and don’t use a 115mm disc on material that needs a 230mm cut – the first is extremely dangerous, the second is just inefficient.
Cutting Wheel Comparison Guide
Choosing the right cutting disc depends on material, thickness, tool, and job requirements. The comparison table below helps you decide quickly.
| Type | Application | Key Advantage |
|---|---|---|
| 1mm Disc (Ultra‑Thin) | Sheet metal (≤3mm), thin‑wall tubes, precision cutting | Fast cutting, low heat, narrow kerf, minimal burrs – often no finishing needed |
| 3mm Disc (Thick) | Thick plates (≥15mm), solid bars, large structural sections | High durability, impact resistance, long life – ideal for stationary saw batch work |
| INOX Disc (Stainless) | 304/316 stainless steel sheets, pipes, profiles | Fe+S+Cl ≤0.1% pure formulation – no contamination, no rust, silver‑bright cuts |
| Metal Disc (General‑Purpose) | Carbon steel, structural steel, cast iron, and other ferrous metals | Cost‑effective, wide application range, fast cutting – brown fused alumina abrasive offers economy and durability |
Thin sheet → thin disc (fast), thick material → thick disc (durable), stainless → dedicated INOX disc (prevents contamination), carbon steel → general‑purpose disc (cost‑effective). Each of the four types has its own role – no single “universal” disc can replace the performance of a dedicated one. Choose the right disc, and you get efficiency, quality, and safety all at once.

Manufacturing Process
DOME’s resin‑bonded cutting discs are manufactured through a rigorous, standardised process. Every step, from raw materials to finished goods, is precisely controlled to ensure consistent performance and safety.
1. Raw Material Preparation – Everything starts at the source. We strictly select and prepare key raw materials according to the product formulation – abrasive grains, phenolic resin powder/liquid, fillers, and fiberglass mesh for reinforcement. All incoming materials pass through incoming inspection to ensure quality from the very beginning.
2. Mixing – Precisely weighed raw materials – abrasives, resin, fillers – are loaded into a mixer and thoroughly blended. This step is critical – it ensures every disc has consistent performance from the start.
3. Pressing – The mixed material is layered into a mould together with fiberglass mesh – which acts as the reinforcing skeleton. It is then pressed under 200–300 bar of pressure to form a “green disc” with precise thickness and diameter. For stainless steel cutting discs, a dedicated INOX formulation is used in this step.
4. Curing – The green disc has its shape, but is not yet strong enough. The discs are then placed into curing ovens and baked in a stepped temperature cycle at approximately 180–200°C. During this process, the resin undergoes cross‑linking, firmly bonding the abrasive grains together – giving the disc its final hardness and strength.
5. Quality Control – After curing, the discs undergo a series of stringent quality checks:
- Dimensional & Visual Inspection – checking for cracks, bubbles, or surface defects.
- Hardness & Balance Testing – verifying hardness and dynamic balance meet specifications.
- Strength & Performance Testing – including EN12413‑standard burst testing (burst speed ≥ 1.5× rated maximum RPM), and cutting performance tests under simulated working conditions.
6. Packaging – All discs that pass inspection are individually sealed to prevent moisture damage. They are then labelled with key information – including specifications and maximum RPM – and packed into cartons with complete traceability data, ready for shipment to customers worldwide.

Custom Cutting Wheel User Feedback
FAQ
1: What is the difference between a resin cutting disc and a diamond blade?
Resin cutting discs are used for cutting metal – abrasive grains perform micro‑cutting to separate the material. Diamond blades are used for cutting hard brittle materials like stone and concrete – the abrasive type and bond system are completely different. They are not interchangeable.
2: What is the difference between T41 and T42 cutting discs?
T41 (Type 1) is a flat disc with no recess – designed for 90° straight cutting. T42 (Type 27) has a depressed centre – the recess provides clearance for corner cutting and flush cutting, offering better cutting angles and visibility.
3: How do I know if I’ve chosen the right disc thickness?
Thin sheet (≤3mm) → 1.0mm ultra‑thin disc. Medium plate (3–15mm) → 1.6mm standard disc. Thick plate / solid bar (≥15mm) → 2.5–3.0mm heavy‑duty disc. The thicker the workpiece, the thicker the disc you need.
4: Can I use the same cutting disc for stainless steel and carbon steel?
Not recommended. A disc used on carbon steel picks up carbon steel particles. When used on stainless afterwards, these particles contaminate the surface – iron embedment leads to future rust. Stainless cutting discs should be dedicated to stainless only.
5: Why does my cutting disc wobble during use?
Possible causes: disc bore size doesn’t match the grinder spindle, the disc itself is out of balance, the grinder spindle is worn, or the flange nuts are not tightened properly. Test the disc on a balancing machine first to rule out disc issues, then check the tool.
6: Can I use a 115mm disc on a 125mm angle grinder?
No. 115mm discs go on 115mm grinders; 125mm discs go on 125mm grinders. Diameter mismatch creates improper guard clearance – a serious safety hazard.
7: Does a larger disc diameter mean deeper cuts?
Yes. Cut depth is roughly one‑third of the disc diameter: 115mm → ~35mm, 230mm → ~75mm, 355mm → ~120mm. But the diameter must match your tool – bigger is not always better.
8: Can I use a 355mm disc on a 230mm angle grinder?
Absolutely not. 355mm discs are designed exclusively for stationary chop saws. Mounting one on a hand‑held grinder is extremely dangerous – the disc won’t fit the guard properly, and if it shatters at high speed, the consequences are severe. Large‑diameter discs are never for hand‑held use.
9: Is there a relationship between disc thickness and bore size?
No – thickness and bore size are independent. Thickness determines cutting speed and durability; bore size determines whether the disc fits your tool. Check both: thickness for your material, bore for your tool spindle.
10: What is the minimum order quantity for OEM customisation?
MOQ varies based on the customisation scope. Standard sizes with packaging customisation have lower MOQs. Custom formulas, non‑standard sizes, or special colours have higher MOQs. Please provide your target specifications and annual volume – we’ll give you an accurate quote based on process complexity and tooling costs.
11. What is the lead time for custom cutting discs?
Standard lead time is approximately 30 days. With packaging materials ready, delivery can be as fast as 20 days. Formula development and certification support (e.g., MPA) may add 7–15 days of development time.
12. What customisation options are available for OEM cutting discs?
Specification customisation (diameter, thickness, bore size), abrasive formula customisation (abrasive type, bond hardness, grit size), colour customisation, label and carton branding, individual shrink‑wrap packaging, and more – full‑chain customisation from formula to packaging.
13. Can I get samples for testing?
Yes. DOME provides free samples for client testing and validation. Test cutting speed, service life, and cut quality on your own equipment – production proceeds only after your approval.
14. What does the maximum RPM on a cutting disc mean?
It is the maximum safe operating speed for the disc. Your angle grinder’s actual RPM must be lower than the disc’s rated maximum RPM. Exceeding the limit creates excessive centrifugal force – the disc can shatter and cause serious injury.
15. Why do cutting discs break?
Common causes: overspeed (most frequent), using expired or moisture‑damaged discs, improper mounting (loose flanges or bore mismatch), using a cutting disc for grinding or side loading, or pre‑existing cracks and defects in the disc.
