3M 7100100635 Quick-change Disc 800 Grit Diamond 1.5 in

Product Description

The 3M 7100100635 is a quick-change coated abrasive disc designed for fine surface finishing and precision material removal. Built on a flexible polyester backing with a J-weight grade, it carries an 800-grit diamond abrasive rated for up to 30,000 RPM. The disc measures 1.5 inches in diameter and attaches via the Type R (Roloc TR) twist-lock system for fast pad changes without tools. It is suited for metal, ceramic, and hard-material finishing tasks where consistent scratch patterns and tight grit tolerances matter. Technicians and machinists working on close-tolerance surfaces will find the diamond abrasive maintains cut consistency longer than conventional aluminum oxide alternatives.

This disc fits applications requiring controlled micro-finishing on small surface areas, including deburring, blending weld seams, and preparing hard metal or ceramic components. The 1.5-inch diameter is well suited for tight clearances and detail work on fabricated assemblies. The Type R attachment system is compatible with standard Roloc TR backup pads found on die grinders and right-angle tools commonly used in HVAC fabrication shops, plumbing rough-in work, and general metalworking environments. Each unit is sold individually.

Installation Notes

Seat the disc firmly onto the Type R backup pad by pressing and turning until the twist-lock engages fully before starting the tool. Verify the tool spindle speed does not exceed 30,000 RPM prior to use. Wear appropriate eye and face protection during grinding operations. Inspect the disc and backup pad for wear or damage before each use and replace if backing separation or delamination is observed.
