When it comes to cutting through metal with speed, precision, and safety, resin cutting discs are one of the most trusted tools in workshops and job sites around the world. Whether you’re working with carbon steel, stainless steel, or aluminum, these discs deliver clean, burr-free results with minimal effort.
🔍 What Is a Resin Cutting Disc?
A resin cutting disc is an abrasive wheel made by bonding grains of abrasive material with a synthetic resin. Most are reinforced with fiberglass mesh to improve durability and reduce the risk of shattering at high speeds.
Key Benefits:
- Thin profile for faster, cooler cutting
- Suitable for handheld angle grinders and stationary machines
- Excellent for cutting rebar, pipes, angle iron, and sheet metal

🧰 Applications in Metal Cutting
Resin cutting discs are commonly used in:
- Fabrication workshops
- Construction sites
- Auto repair
- Plumbing and electrical installation
- Shipbuilding and metalworking industries
A popular use case is cutting steel channels, conduits, and angle iron. For this, a thin 4-1/2” resin disc mounted on an angle grinder is ideal.
🧼 Safety Tips for Resin Cutting Discs
- ✅ Always wear gloves, goggles, and a face shield
- ✅ Use the proper disc size for your grinder
- ✅ Never side-grind with a cutting disc
- ✅ Let the tool reach full speed before making contact
🧩 Choosing the Right Disc
| Material | Recommended Grit | Notes |
|---|---|---|
| Mild Steel | 36–60 | General cutting |
| Stainless Steel | 60–80 | Look for “Inox” or “iron-free” |
| Aluminum | 46–60 | Use discs designed to prevent loading |
📌 Tip: For stainless steel, use resin discs labeled Inox to avoid contamination and rusting.
