Angle iron is a staple in metal fabrication, used for building frames, supports, and structural reinforcements. When it comes to cutting this durable L-shaped steel, resin cutting discs are among the most efficient and affordable tools available. In this article, we’ll explore what makes resin discs ideal for angle iron, how to choose the right one, and where to find them.
🔧 Why Use Resin Cutting Discs for Angle Iron?
Resin cutting discs, also known as resin-bonded abrasive wheels, are made by binding abrasive grains with synthetic resin. They are known for their:
- Fast, precise cutting
- Low cost and wide availability
- Ability to handle ferrous and non-ferrous metals
When used with an angle grinder or cut-off machine, these discs make clean, efficient cuts in angle iron without excessive heat buildup.

🛠️ Choosing the Right Resin Cutting Disc for Angle Iron
When selecting a disc for cutting angle iron, consider the following:
| Feature | Recommendation |
|---|---|
| Diameter | 4.5” to 7” for hand-held grinders, 14”+ for chop saws |
| Thickness | 1.0mm to 3.2mm depending on cut speed vs. durability |
| Material | Aluminum oxide or zirconia for carbon/mild steel |
| Reinforcement | Fiberglass mesh for added strength and safety |
A thinner disc (1.0–1.6mm) offers faster cuts and less material loss, while thicker ones (2.5–3.2mm) provide greater stability for rugged jobs.
