3M 7010309472 Quick-change Disc 200 Grit Diamond 1 Inch

Product Description

The 3M 7010309472 is a quick-change abrasive disc designed for precision material removal and finishing on hard surfaces. Part of the 3M 6234J series, it features a diamond abrasive material at 200 grit, making it well-suited for fine finishing passes on carbide, ceramic, glass, and hardened steel. The disc uses a Type R (Roloc TR) twist-lock attachment system for fast one-handed mounting and removal on compatible angle grinders and die grinders. Backed with a flexible J-weight polyester backing, it conforms to contoured workpieces without loading. Rated to 30,000 RPM, this 1 inch disc is installed by machinists, tool-and-die techs, and maintenance mechanics.

This disc is appropriate for precision deburring, lapping, and surface conditioning tasks in industrial and maintenance settings. The 200 grit diamond abrasive is a standard choice when working materials that defeat conventional aluminum oxide or silicon carbide media. Its compact 1 inch diameter suits tight access areas and small-radius workpieces where larger discs cannot reach. The flexible polyester backing allows light contouring work without fracturing the abrasive layer.

Installation Notes

Installation and disc changes should be performed with the grinder powered off and disconnected from its power source. Thread the Type R button into the compatible disc holder and rotate until it locks securely before powering the tool. Verify the tool spindle RPM does not exceed the 30,000 RPM disc rating before operation. Inspect the disc for damage before each use and discard any disc showing cracks, tears, or delamination.
