Selecting Wheels

Grinding is the cutting action of thousands of abrasive grains on the face of a grinding wheel. When grinding metals such as steel and iron, choose an aluminum oxide grinding wheel. Select a silicon carbide grinding wheel for stone and concrete. Use cotton reinforced wheels for non-ferrous metals.

Type 27 Reinforced 1/8" thick or less Cut-Off Wheels are suited for small cut-off and shallow notching operations only.
