3M 7100066562 Flexible Diamond Qrs Cloth Disc 5 in

Product Description

The 3M 7100066562 is a flexible diamond QRS cloth disc engineered for aggressive stock removal on hard-to-grind materials including stone, glass, ceramics, carbides, and composites. The disc uses micron-graded diamond mineral secured with a metal bond, delivering consistent scratch patterns and repeatable cut rates across the surface. An open dot mineral pattern keeps the grinding face clear by allowing swarf and debris to escape, reducing loading during use. The semi-flexible backing conforms to edges and contours, making it effective on workpieces that are not flat. Quick-release attachment speeds disc changes on compatible random orbital tools.

This disc is suited for fabrication, finishing, and surface preparation work in stone and glass shops, composite manufacturing, and carbide tooling applications. It is commonly used by machinists, fabricators, and finishing technicians who need reliable material removal on substrates that defeat conventional abrasive minerals. The 5 inch diameter and 1 inch arbor fit standard disc tool configurations used in light industrial and workshop environments.

Key Features

• Micron-graded diamond mineral bonded with metal bond for aggressive, consistent cut on hard substrates
• Open dot mineral pattern prevents loading by allowing swarf and debris to escape
• Semi-flexible backing conforms to edges and contours for accurate finishing
• Quick-release attachment for fast disc changes on compatible tools
• 5 inch diameter with 1 inch arbor fits standard disc configurations

Compatibility

Designed for use with quick-release random orbital and disc grinding tools accepting a 5 inch diameter, 1 inch arbor abrasive disc.

Installation Notes

Installation and disc changes should be performed with the tool powered down and unplugged or locked out per applicable safety procedures. Verify the tool arbor size and maximum RPM rating before mounting; do not exceed the disc speed rating. Inspect the disc for damage before each use and replace if the backing shows delamination or the mineral surface is unevenly worn.
