3M™ Cubitron™ II Flap Disc 967A 4 1/2" X 7/8" Type 27 Grade 40+ 55605
Genuine 3M™ Cubitron™ II 967A grade 40+ 4 1/2" flap disc grinds, blends and finishes with more speed and less pressure than any other flap disc on the market. The key to Cubitron™ II's outstanding performance is 3M's precision-shaped grain technology. Unlike most ceramic grinding abrasives, Cubitron™ II triangle-shaped grain stays sharp for the life of the disc. The abrasive grain is also electronically oriented on the surface of the disc to continuously form sharp abrasive "peaks" and to provide more abrasive material than competitive brands.
The Cubitron™ 967A flap disc is ideal for grinding, weld removal, deburring and finishing. It features grade 40+ (40 grit) abrasive material with a grinding aid to help keep the disc cool on heat sensitive metals. Flaps are backed with Y-weight poly-cotton which exposes more abrasive material as the disc is worn away and provides flexibility while working with unusual shapes. The 967A is a Type 27, depressed center flap disc with a 7/8 inch (no hub) arbor. It operates on 13,300 max RPM.Applications
