Cutting metal is a demanding task that requires the right tools for safety, speed, and precision. Whether you’re slicing through rebar, sheet metal, stainless steel, or structural steel, cutting discs—also known as cut-off wheels—are a go-to solution for professionals and DIYers alike.
But what makes a good cutting disc for metal? Let’s dive into the essentials.
🔧 What Is a Cutting Disc?
A cutting disc is a type of abrasive wheel used with angle grinders or stationary machines to cut through metal and other materials. It consists of abrasive grains bonded together by resin, often reinforced with fiberglass for extra durability.
There are various types of cutting discs, but for metalwork, the most common are:
- Resin-bonded cutting discs
- Thin cut-off wheels
- Reinforced cut-off wheels
🛠️ Key Features to Look For
When choosing a cutting disc for metal, consider the following:
1. Material Compatibility
Ensure the disc is rated for the type of metal you’re cutting—mild steel, stainless steel (Inox), or non-ferrous metals.

2. Disc Thickness
Thinner discs (e.g., 1.0mm or 1.2mm) provide faster, cleaner cuts with less material loss and heat buildup—ideal for sheet metal. Thicker discs offer more durability for heavier sections.
3. Reinforcement
Look for fiberglass-reinforced discs, which add safety and resistance to shattering under high RPM.
4. RPM Rating
Always match the disc’s maximum RPM rating with your grinder. Overspeeding is dangerous and can cause disc failure.
