Product Overview
The 3M™ PSA Cloth Disc 777F features 3M-engineered high-performing ceramic abrasive grain blended with aluminum oxide for a combination of durability and cutting efficiency that increases productivity for both stock removal and finishing. The heavy, water-resistant polyester backing supports medium-pressure applications, a consistent cut-rate, and both wet and dry applications.The 3M PSA Cloth Disc 777F is resin-bonded to withstand high heat and pressure. A grinding aid on the disc reduces grinding temperatures to protect heat-sensitive alloys such as stainless steel and nickel alloys. 3M Ceramic Abrasive Grain is a ceramic mineral designed to enhance toughness and hardness of the grain. For increased performance, the 3M PSA Cloth Disc 777F features aluminum oxide mineral blended with 3M ceramic abrasive grain which is one of the hardest, longest-lasting minerals available. Perfect for moderate to heavy stock removal, ceramic abrasives are engineered to cut fast and handle intense heat and stress applications. Ceramic aluminum oxide blends surpass aluminum oxide abrasives in cut-rate and durability making them an excellent choice for difficult grinding applications.
