Stone, Light Blue, Cylinder, 3/16", 1/8" shank
These mounted stones incorporate a unique Sol Gel ceramic abrasive (3M Cubitron grain). The Sol Gel abrasive, produced by Sol Gel processing, is both hard and tough. It provides exceptional durability and cut rates in grinding mild, high-carbon and stainless steel as well as many nonferrous alloys. Under normal use, cut rate and wheel life are two to three times that of Red and Blue Mounted Stones.
