Our 3M Roloc Disc 777F is resin-bonded to withstand high heat and pressure. A grinding aid on the 777F 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, 3M Roloc Disc 777F products feature 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.
3M Roloc Disc 777F is available for use with the following Roloc attachment systems: TSM, TR, TP and TS. Please select discs with the attachment design made for your system.
