3M Roloc TR 45091 3″ Hard Disc Pad Backup – 1/4-20 Internal, 20 000 RPM

Rugged support for aggressive grinding

The 3M™ Roloc™ Disc Pad TR 45091 is built to keep heavy-cut abrasives flat and stable. If you’re using a pad like the 3M Roloc 3-inch disc pad, its hard-density rubber face resists deflection on weld seams and edges, giving you consistent material removal while helping discs last longer. A molded Roloc TR quick-change hub lets you swap discs with a single twist—no wrenches, zero downtime. The 1/4-20 internal thread bolts straight to your pneumatic or electric grinder, and the pad stays balanced up to 20 000 RPM for chatter-free results.

Key features
