3M 7010328306 Quick-change Disc 60 Grit Diamond 1-1/2 in

Product Description

The 3M 7010328306 is a coated abrasive quick-change disc designed for use with Roloc TR Type R attachment systems. It features a 60-grit diamond abrasive on a flexible polyester (J-weight) backing, making it well suited for grinding, blending, and surface preparation on hard materials. The disc measures 1-1/2 inches in diameter and is rated for a maximum spindle speed of 30,000 RPM. It is part of the 3M 6234J series and carries a Grade M250 designation. Metal fabricators, maintenance technicians, and trade professionals working with angle grinders or die grinders in tight-access areas will find this disc practical for consistent material removal on hard surfaces.

This disc is intended for surface conditioning and material removal tasks in fabrication shops, maintenance facilities, and field service environments. Its compact 1-1/2-inch diameter makes it effective in confined spaces where larger discs cannot reach. The flexible polyester backing conforms to irregular surfaces, and the diamond abrasive composition supports use on hard materials including ceramics, carbide, glass, and hardened metals. It is sold individually, making it easy to stock as a single replacement disc.

Compatibility

Designed for use with Roloc TR (Type R) quick-change tool holders and mandrels. Verify that the grinder or die grinder being used accepts Type R discs and is rated at or above the disc speed rating before mounting.

Installation Notes

Installation requires a compatible Type R Roloc TR mandrel threaded into an angle grinder or die grinder. Power down and disconnect the tool from its power source before mounting or removing the disc. Confirm the tool spindle speed does not exceed 30,000 RPM before operation. Operators should wear appropriate eye protection and observe applicable workplace safety standards when using coated abrasive products.
