From the Manufacturer

The 3M™ Roloc™ 777F cloth disc provides a quick-change attachment and 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 disc is resin-bonded to withstand high heat and pressure. A grinding aid 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 using a 3M patented process to enhance toughness and hardness of the grain. For increased performance, 777F products feature aluminum oxide blended with 3M ceramic abrasive grain for one of the most durable, 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 TS quick change discs have a threaded hole designed to easily and quickly attach to a Roloc TS disc pad (sold separately) so that operators can conveniently change discs with a simple twist-off, twist-on motion. No tools are needed, and this quick and convenient method provides a secure attachment and saves operators time when switching discs between grades or applications.
