From the Manufacturer
The 3M™ Roloc™ Durable Edge Disc 977F TR is a quick-change disc that features 3M’s high-performing ceramic abrasive grain on a laminated YF-weight polyester backing for outstanding durability and cutting efficiency, making fast work of light to medium pressure wet or dry applications. Use this disc for dimensioning parts, deburring, grinding and blending welds, and grinding and finishing castings or forgings. Where traditional cloth discs may fray or break down at the edges, the 977F durable edge disc provides outstanding performance on edge work, even on contours. Ceramic grain with reinforced backing improves durability, disc life, and cut-rate, offering greater throughput in less time. Less pressure is required to achieve maximum cut-rate, which reduces operator fatigue. The disc is resin-bonded to withstand high heat and pressure, and a grinding aid reduces grinding temperatures to protect heat-sensitive alloys such as stainless steel and nickel alloys.
Abrasives made with 3M ceramic abrasive grain have outstanding durability, cut exceptionally fast, and have a long service life. 3M ceramic abrasive grain is a 3M proprietary ceramic mineral formed using a patented process to enhance toughness and hardness of the grain. It is chemically engineered with a unique “stay sharp” crystalline structure, which continually reveals fresh cutting edges on the surface of the disc, ensuring extended high performance and enabling operators to do more work in less time, for significant gains in both ergonomics and productivity.
3M Roloc TR quick change discs have a plastic 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. The Roloc TR system provides a secure attachment, 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 by grade, making it easy to identify the grade required for different applications.
