METAL CUT-OFF WHEELS FAQ's
What is a metal cut-off wheel?

A metal cut-off wheel is a type of abrasive wheel that can cut through metal and other hard materials using a forward motion. Metal cut-off wheels are made by bonding sharp abrasive grains, such as aluminum oxide or silicon carbide, together with resin. Metal cut-off wheels are thin enough to make a clean cut and rigid enough to withstand high speeds and pressures.

Metal cut-off wheels can be fitted to various power tools, such as angle grinders, straight grinders, chop saws, etc., depending on the size and shape of the wheel and the material being cut. Metal cut-off wheels come in different diameters, thicknesses, and types, depending on the type of material and cut you want to achieve.

What are the types of Meta Cut-Off Wheels?

  • Type 1 wheels, which have a flat shape and are used for straight cutting on flat surfaces.
  • Type 27 wheels, which have a depressed center and are used for cutting and light grinding on angled surfaces.
  • Type 41 wheels, which have a flat shape with a reinforced center and are used for heavy-duty cutting on flat surfaces.
  • Type 42 wheels, which have a depressed center with a reinforced center and are used for heavy-duty cutting and light grinding on angled surfaces.
How to Keep Meta Cut-Off Wheels Sharp?

  • Use proper lubrication when cutting metal. Lubrication helps to reduce friction and heat, which can cause the wheel to glaze over or lose its sharpness. Lubrication also improves the quality of the cut and the life of the wheel.
  • Dress the wheel regularly. Dressing the wheel means removing the glazed or dull layer of abrasive grains on the edge of the wheel and exposing a fresh layer of sharp grains. This can be done by cutting it into a hard material, such as a grinding wheel or a dressing stick, for a few seconds. Dressing the wheel can restore its cutting performance and extend its life.
  • Clean the wheel properly after each use. You should clean the wheel with a soft brush and a gentle solvent to remove any dirt or debris that may have accumulated on the wheel. This can prevent corrosion and rust, which can affect the quality and life of the wheel.
