Ceramic Redline CBT Maxidisc

Pearl’s Ceramic Bonded Technology (CBT) grain is a non-fused ceramic aluminum oxide that is Extremely Strong and Durable. It is a very fine crystalline structure, which allows for micro-fracturing of the abrasive grain. This promotes constant generation of new cutting edges allowing for longer life and faster stock removal throughout the entire life of the wheel. In addition, CBT grains perform exceptionally well on stainless steel.
