3M 7000120336 Flexible Diamond Qrs Cloth Disc 5 in

Product Description

The 3M 7000120336 is a Flexible Diamond QRS Cloth Disc engineered for grinding hard-to-machine materials where conventional abrasives fall short. The disc uses micron-graded diamond mineral locked in place with a metal bond, delivering aggressive, consistent cutting action on stone, glass, ceramics, carbides, and composites. The semi-flexible backing conforms to edges and contoured surfaces, maintaining contact and reducing chatter. At 5 inches in diameter with a 1-inch arbor, it mounts quickly via a quick-release attachment system, reducing changeover time during production or field work.

This disc is suited for fabrication shops, grinding operations, and finishing work involving hard or brittle materials. Typical applications include surface grinding and edge work on stone slabs, technical ceramics, carbide tooling, and composite panels. The open dot mineral pattern allows swarf and debris to escape the cutting zone, reducing loading and extending usable disc life. It is a practical choice for trade professionals and fabricators who cycle through abrasives on demanding materials regularly.

Key Features

• Micron-graded diamond mineral delivers aggressive cut and consistent scratch pattern on hard-to-grind materials
• Metal bond securely anchors diamond to the disc surface for stable, long-lasting cutting action
• Open dot mineral pattern promotes swarf and debris evacuation, reducing loading
• Semi-flexible backing conforms to contours and edges for consistent contact
• Quick-release attachment system speeds disc changes
• 5-inch diameter with 1-inch arbor fits standard angle grinders and disc tools

Compatibility

Designed for use with standard 5-inch quick-release disc tools and angle grinders accepting a 1-inch arbor; intended for use on hard-to-grind materials including stone, glass, ceramics, carbides, and composites.

Installation Notes

Installation should be performed by qualified personnel familiar with abrasive disc safety practices. Confirm the tool spindle speed does not exceed the maximum rated speed marked on the disc before mounting. Power down and disconnect the tool from its power source before changing discs. Inspect the disc for cracks or damage before each use and never use a damaged abrasive.
