3M 7100081718 Flexible Diamond Qrs Cloth Disc 1.5 in

Product Description

The 3M 7100081718 is a Flexible Diamond QRS Cloth Disc engineered for grinding hard-to-work materials that conventional abrasives struggle to cut effectively. Built around micron-graded diamond mineral held in place by a metal bond, this disc delivers aggressive cutting action and consistent scratch patterns on demanding surfaces. The semi-flexible backing allows the disc to conform to edges and contours rather than riding flat, making it practical for profiling and finishing irregular geometry. Sold individually, it is sized at 1.5 inches in diameter and weighs 0.01 pounds, making it suited for precision hand-tool or low-clearance power-tool applications.

This disc is intended for use on hard-to-grind materials including stone, glass, ceramics, carbides, and composites. It is a fit for fabrication shops, tool-and-die operations, and specialty trade work where conventional aluminum oxide or silicon carbide abrasives break down too quickly. The quick-release QRS attachment system allows fast disc changes during production or service work. The open dot mineral pattern keeps the cutting surface clear by allowing swarf and debris to escape, reducing loading and extending usable disc life.

Key Features

• Micron-graded diamond mineral provides aggressive cut and consistent scratch pattern on stone, glass, ceramic, carbides, and composites
• Metal bond anchors diamond securely for controlled, repeatable material removal
• Open dot mineral pattern allows swarf and debris to escape, reducing loading
• Semi-flexible backing conforms to edges and contours for accurate profile grinding
• Quick-release QRS attachment for fast, tool-free disc changes

Compatibility

Designed for use with QRS-compatible random orbital and disc-type power tools on hard-to-grind materials including stone, glass, ceramics, carbides, and composites.

Installation Notes

Installation and disc changes should be performed with the power tool unplugged or the air supply disconnected. Verify that the tool spindle speed does not exceed the rated maximum speed of the disc before operation. Eye protection, gloves, and appropriate respiratory protection are recommended when grinding ceramics, glass, or composite materials. Inspect the disc for damage before each use and replace if the backing or mineral surface shows signs of delamination or excessive wear.
