3M 7100076925 Quick-change Disc 80 Grit Ceramic 2 in

Product Description

The 3M 7100076925 is a 2-inch ceramic abrasive quick-change disc designed for aggressive material removal on metal and composite surfaces. Part of the 3M 947A series, it uses a Type R attachment system for fast, tool-free disc swaps on compatible right-angle grinders and die grinders. The ceramic abrasive grain delivers consistent cut rates and resists heat buildup, making it well-suited for high-pressure grinding applications. At 80 grit, it falls in the medium grade range, effective for weld blending, surface prep, and stock removal. The polyester cloth backing with X-weight construction provides the rigidity needed to maintain grain contact under load.

This disc is intended for use in fabrication shops, manufacturing environments, and field metalwork where frequent disc changes slow productivity. The Type R quick-change button system allows one-handed mounting and removal without a wrench. Typical applications include deburring, edge grinding, and surface conditioning on steel, stainless, and aluminum workpieces. It is used by welders, pipefitters, machinists, and general fabricators requiring a small-diameter disc for tight clearance work.

Installation Notes

Installation and disc changes should be performed with the grinder powered off and unplugged or air supply disconnected. Thread the Type R button onto the compatible backing pad by hand until seated before operation. Always confirm the disc RPM rating meets or exceeds the tool's no-load RPM before use. Wear appropriate PPE including eye protection and gloves when operating abrasive grinding equipment.
