94AB: Advanced grain technology used in Cylindrical and Centerless grinding wheels. This grain can be used to grind steels in either soft or hard state.
WAG: Highly friable grain with special bond characteristics for fast, cool cutting action and extended life over traditional aluminum oxide wheels.
PASP: Special pink formulation for precision grind applications. Tough, but very friable. Produced with new high performance VD ceramic bond for cooler cutting and longer life.
GC: Green Silicon Carbide – Quickly grinds non-ferrous metals and sharpens tungsten carbide tools. Used on titanium and cemented carbide.
72C: Black Silicon Carbide – for non-ferrous metals.
