3M 7000045628 Quick-change Disc 3 in 50 Grit Ceramic Roloc Tr

Product Description

The 3M 7000045628 is a 3-inch ceramic coated abrasive disc designed for use with Roloc TR quick-change systems. Built on a YF-weight polyester cloth backing, it delivers aggressive material removal at a 50 grit coarse grade. The ceramic abrasive grain fractures during use to expose fresh cutting edges, sustaining cut rate over the disc life. Rated to 20,000 RPM, this disc suits high-speed angle grinders and die grinders equipped with Type R locking hubs. It is sold individually with a minimum order quantity of 50 units per order.

This disc is intended for heavy grinding, weld blending, and surface preparation on metal substrates in industrial, fabrication, and maintenance environments. The coarse 50 grit grade handles scale removal, rust elimination, and rapid stock removal. The orange color coding and green button identify the Series 777F product line, aiding quick visual identification in multi-disc shops. Licensed trades including metal fabricators, pipefitters, ironworkers, and maintenance mechanics are the primary installers and users.
