What is a Metal Cutting Disc?

A metal cutting disc (also known as a cut-off wheel) is a thin, circular abrasive tool designed for cutting through different types of metal. It is commonly used with angle grinders, bench grinders, or stationary machines for fast, precise, and clean cuts.


Key Features

  • Material: Usually made with reinforced fiberglass and abrasive grains (aluminum oxide, zirconia, or ceramic).
  • Sizes: Available in diameters such as 4”, 5”, 7”, and 14”.
  • Thickness: Generally ranges between 1mm – 3mm (thin discs cut faster, thicker discs last longer).
  • Speed Rating: Marked with maximum RPM (must match your machine).

Applications

  • Cutting mild steel, stainless steel, cast iron, and aluminum
  • Construction, fabrication, and automotive industries
  • Ideal for sheet metal, pipes, rebar, and profiles

Advantages of Using Metal Cutting Discs


  • Fast & precise cutting
  • Low heat build-up compared to manual methods
  • Durable and long-lasting when used correctly
  • Cost-effective solution for metal fabrication
