3M 7100053375 Flexible Diamond Qrs Cloth Disc 1.5 in

Product Description

The 3M 7100053375 is a Flexible Diamond QRS Cloth Disc engineered for grinding and finishing hard-to-machine materials including stone, glass, ceramics, carbides, and composites. At 1.5 inches in diameter, this disc features micron-graded diamond mineral held in place by a metal bond, delivering aggressive cutting action and consistent scratch patterns. The semi-flexible backing conforms to edges and contours, making it effective on complex surface geometries. Installation is tool-free via the Quick Release System attachment. Fabricators, toolmakers, and finishing technicians working with advanced materials rely on this disc for repeatable material removal on demanding substrates.

This disc is suited for precision grinding, deburring, and surface preparation on hard materials in both shop and field environments. The open dot mineral pattern allows swarf and debris to clear the cutting surface during use, reducing loading and extending usable disc life. Applications include contouring stone, finishing glass edges, grinding ceramic components, and working carbide tooling. The flexible backing makes it especially effective where rigid abrasives would lose contact with curved or profiled surfaces.

Key Features

• Micron-graded diamond mineral for aggressive cut and consistent scratch on stone, glass, ceramic, carbides, and composites
• Open dot mineral pattern channels swarf and debris away from the cutting surface to resist loading
• Metal bond secures diamond securely to the backing for extended service life
• Quick Release System attachment for fast, tool-free disc changes
• Semi-flexible backing conforms to contours and edges

Compatibility

Designed for use with Quick Release System (QRS) compatible random orbital and finishing tools suited to the 1.5 inch disc format. Intended for use on hard-to-grind materials including stone, glass, ceramics, carbides, and composites.

Installation Notes

Installation and removal of the disc is performed using the Quick Release System — no tools required. Ensure the backing pad on the tool is clean and free of debris before attaching the disc. Always follow the tool manufacturer's rated speed limits and wear appropriate eye and respiratory protection when grinding ceramics, glass, or composite materials. Verify work area ventilation is adequate for the material being processed.
