Genuine 3M™ Cubitron™ 3 depressed center 4 1/2" X 1/4" X 7/8" Type 27 grinding wheel is the most advanced ceramic grinding wheel in the world. 3M Cubitron 3's precision-shaped ceramic triangular grain removes metal up to 14% faster and lasts 50% longer than previous 3M Cubitron II grinding wheels. Unlike most ceramic grinding abrasives, the 3M Cubitron 3 re-engineered grain stays sharp for the life of the wheel. Sharper abrasives result in increased speed, reduced heat input and dramatically lower labor costs.

It features grade 36+ (36 grit) abrasive material that removes more metal and stays cooler than competitive wheels. This Type 27, depressed center grinding wheel comes with a 7/8 arbor. It operates at 13,300 max RPM. Volume discounts are available when purchasing in quantities of 20, 100, 200 or 300 wheels.
