Cutting angle iron is a common task in metal fabrication, construction, and general workshop projects. To get clean, efficient cuts through tough metal, resin cutting discs are the go-to solution for professionals and DIYers alike. In this blog, we’ll break down why these discs are ideal for angle iron, how to choose the right one, and where to get them.
🔧 Why Use Resin Cutting Discs for Angle Iron?
Resin cutting discs, also known as bonded abrasive wheels, are composed of abrasive grains held together by a resin bond. These discs are:
- Fast-cutting – They slice through ferrous metals quickly.
- Thin-profiled – Ideal for narrow kerfs and reduced material loss.
- Affordable – Compared to diamond or ceramic wheels.
When working with angle iron, which is commonly made from mild steel or galvanized steel, a resin disc provides:
- ✔️ Minimal burr formation
- ✔️ Reduced heat generation
- ✔️ Controlled, clean cuts

🧱 Best Applications
Resin cutting discs excel at:
- Cutting structural steel like angle iron, flat bar, and channel
- Modifying frames, brackets, and supports
- Fabricating furniture or shelving
⚙️ Choosing the Right Resin Disc for Angle Iron
When selecting a disc, consider:
Feature | Recommended |
---|---|
Diameter | 4.5″ – 7″ for handheld grinders |
Thickness | 1.0mm – 3.0mm (thinner for fast cuts, thicker for durability) |
Material | Aluminum oxide for general steel |
Reinforcement | Double-reinforced for safety and durability |

🛠️ Pro Tips for Cutting Angle Iron
- Secure the workpiece: Use a clamp or vice to prevent movement.
- Wear safety gear: Goggles, gloves, and a face shield are essential.
- Use consistent pressure: Let the disc do the work without forcing it.
