3M 7100100697 Quick-change Disc 1.5 in 200 Grit Diamond

Product Description

The 3M 7100100697 is a quick-change abrasive disc designed for use with Roloc TR-style attachment systems. It features a diamond abrasive material at 200 grit, making it suited for fine finishing and precision surface work on hard materials. The disc measures 1.5 inches in diameter and is backed by a flexible polyester J-weight backing, which allows it to conform to contoured surfaces. Rated at a maximum of 30,000 RPM, it handles high-speed angle grinders and die grinders commonly used in fabrication and maintenance work. The brown disc color corresponds to the 6234J series designation, and the red button indicates the Type R Roloc TR attachment interface.

This disc is used in metalworking, maintenance, and surface preparation applications where a small-diameter, high-speed abrasive is needed. The 1.5-inch size makes it well-suited for tight clearances, weld cleanup, and spot finishing work. The coated diamond abrasive performs on hard surfaces including ceramics, carbide, glass, and hardened metals. It is typically used by machinists, tool-and-die technicians, fabricators, and maintenance professionals working on precision components or hard-to-reach areas.

Installation Notes

Installation requires a Roloc TR-compatible disc holder or backup pad rated for the attachment type. Verify the tool's maximum RPM rating meets or exceeds the disc's 30,000 RPM rating before use. Wear appropriate eye protection and ensure the disc is fully seated and locked onto the holder before powering the tool. Inspect the disc for damage before each use and do not exceed the rated speed.
