3M 7010290815 Flexible Diamond Qrs Cloth Disc 3 in

Product Description

The 3M 7010290815 is a flexible diamond QRS cloth disc engineered for grinding hard-to-machine materials including stone, glass, ceramics, carbides, and composites. The disc features micron-graded diamond mineral bonded in place with a metal bond system, delivering aggressive cutting action and consistent scratch patterns across the workpiece. An open dot mineral pattern allows swarf and debris to clear the surface, reducing loading and extending disc life. The semi-flexible backing conforms to edges and contoured surfaces, maintaining consistent contact throughout the cut. This disc is sold individually and attaches via a quick-release system.

This disc is suited for surface finishing and grinding applications in fabrication shops, glass and stone workshops, and composite manufacturing environments. Trades and applications include tool and die, ceramic finishing, and hard-material surface prep where conventional abrasives lose efficiency or load prematurely. The 3-inch diameter and quick-release attachment make it compatible with standard QRS backup pads used in bench or handheld angle grinder setups.

Key Features

• Micron-graded diamond mineral delivers aggressive cut on stone, glass, ceramics, carbides, and composites
• Open dot mineral pattern promotes swarf and debris evacuation to resist loading
• Metal bond system anchors diamond securely for consistent, repeatable scratch
• Semi-flexible backing conforms to edges and contoured workpiece geometry
• Quick-release attachment for fast disc changes on compatible QRS backup pads

Compatibility

Designed for use with standard QRS (quick-release system) backup pads that accept 3-inch diameter abrasive discs. Best suited for hard-to-grind materials including stone, glass, ceramics, carbides, and composites.

Installation Notes

Mount the disc onto a compatible QRS backup pad before tool operation. Ensure the backup pad and angle grinder or die grinder are rated for the disc diameter and operating speed before use. Power down and disconnect the tool before attaching or removing the disc. Follow applicable shop safety and PPE requirements when grinding ceramics, carbides, or composite materials.
