3M 7010309451 Flexible Diamond Qrs Cloth Disc 5 in

Product Description

The 3M 7010309451 is a Flexible Diamond QRS Cloth Disc engineered for grinding hard-to-cut materials including stone, glass, ceramics, carbides, and composites. The disc uses micron-graded diamond mineral held in place by a metal bond, delivering aggressive and consistent cutting action. An open dot mineral pattern allows swarf and debris to escape, reducing loading during use. The semi-flexible backing conforms to edges and contours, making this disc well-suited for detail work on irregular surfaces. Installers and fabricators working with specialty materials rely on this disc where conventional abrasives fall short.

This disc is used in industrial fabrication, stone and tile work, glass finishing, and composite material processing. The quick-release QRS attachment system allows fast disc changes without additional tooling, supporting high-throughput production environments. The 5-inch diameter and 1-inch arbor sizing fit standard angle grinders and disc sanders commonly used in trade and fabrication shops. It is appropriate for both shop-bench and on-site grinding applications where surface control on hard materials is required.

Key Features

• Micron-graded diamond mineral delivers aggressive cut and consistent scratch pattern on hard-to-grind materials
• Open dot mineral pattern channels swarf and debris away from the work surface to prevent loading
• Metal bond securely anchors diamond abrasive for extended service life
• Semi-flexible backing conforms to contours and edges for precise material removal
• Quick-release QRS attachment enables rapid disc changes without extra tools

Compatibility

Designed for use with standard angle grinders and disc sanders accepting a 5-inch diameter disc with a 1-inch arbor and QRS quick-release attachment systems.

Installation Notes

Mounting and disc changes should be performed with the grinder or sander fully powered off and unplugged. Verify that the tool spindle speed rating meets or exceeds the disc maximum RPM before operation. Eye protection, hearing protection, and appropriate respiratory protection should be worn when grinding stone, ceramics, or composites. Inspect the disc for damage before each use and discard if any cracking or delamination is observed.
