The 3M Roloc 777F cloth disc 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, YF-weight polyester backing further supports high-pressure applications and a consistent cut-rate. This disc can be used for both wet and dry applications and the incorporated grinding aid reduces grinding temperatures making it ideal for stainless steel and other heat-sensitive 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 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 TR quick change discs have a threaded button designed to easily and quickly attach to a Roloc TR disc pad (sold separately) so that operators can conveniently change discs with a simple twist-off, twist-on motion. This system provides a secure attachment even for heavy-duty applications, and the variety of available 3M Roloc discs allows swapping from one application to the next in seconds. Each TR attachment button is also color-coded to identify its grade, making it easy to grab the grade required for different applications.
