Pearl Abrasives 4540CB 4-1/2 x 7/8 Redline CBT Maxidisc Flap Discs, Type 27 Shape (packs of 10)

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.Faster stock removal compared to A.O. and Zirconia resin fiber discsLonger life compared to A.O. and Zirconia resin fiber discsGrinds cool - Doesn't burn the work pieceGrains remain sharp through entire life of the wheel - "self sharpening"Exceptional performance on stainless steel and other high tensile alloysConsistent surface finishesResist glazing and loadingType 27Fiberglass backing for high flexibilityRedline CBT (Ceramic Bond Technology)For ferrous metals, iron, steel, stainless steel, hard Materials
