3M 7010309471 Flexible Diamond Qrs Cloth Disc 1.5 in

Product Description

The 3M 7010309471 is a flexible diamond QRS cloth disc engineered for cutting and finishing hard-to-grind materials including stone, glass, ceramics, carbides, and composites. The disc uses micron-graded diamond mineral held in place by a metal bond, delivering aggressive cutting action and consistent scratch patterns across demanding substrates. An open dot mineral pattern allows swarf and debris to escape during use, reducing loading and maintaining cut rate. The semi-flexible backing conforms to edges and contours, making it suitable for both flat and curved workpiece surfaces. Each disc measures 1.5 inches in diameter and weighs 0.01 pounds.

This disc is used in grinding, lapping, and finishing applications where conventional abrasives fail to hold up against hard or brittle materials. Typical install scenarios include precision fabrication shops, tool and die operations, and composite finishing environments. The quick-release QRS attachment system speeds disc changes on compatible random orbital and disc sanders, reducing downtime during production runs. It is suited for both bench and handheld tool applications where contour-following capability is required.

Key Features

• Micron-graded diamond mineral delivers aggressive cut and consistent scratch on hard-to-grind materials
• Open dot pattern allows swarf and debris to escape, reducing disc loading
• Metal bond anchors diamond securely for extended service life
• Semi-flexible backing conforms to edges, curves, and contoured surfaces
• Quick-release QRS attachment for fast, tool-free disc changes

Compatibility

Designed for use with QRS-compatible random orbital and disc sanding tools; intended for grinding and finishing of stone, glass, ceramics, carbides, and composite materials.

Installation Notes

Installation is performed by fabricators, machinists, or finishing technicians using QRS-compatible power tools. Ensure the tool is powered off and disconnected from its power source before attaching or removing the disc. Verify the disc is fully seated and locked on the backing pad before operating the tool. Always use appropriate personal protective equipment including eye protection and gloves when working with abrasive discs on hard or brittle materials.
