3M 7100074475 Flexible Diamond Qrs Cloth Disc 1 in

Product Description

The 3M 7100074475 is a flexible diamond quick-release sanding disc engineered for grinding hard-to-machine materials including stone, glass, ceramics, carbides, and composites. The disc uses micron-graded diamond mineral bonded in metal to deliver aggressive, consistent cutting action across the full working surface. An open-dot mineral pattern allows swarf and debris to clear freely, reducing loading during use. The semi-flexible backing conforms to edges and contours, making this disc effective where rigid abrasives lose contact. Trade professionals in fabrication, tool and die, and surface finishing rely on this disc for controlled material removal on demanding substrates.

This disc is suited for use in shops and field settings where standard aluminum oxide or silicon carbide abrasives underperform. Typical applications include precision grinding of glass and ceramic components, finishing carbide tooling, and surface work on composite materials. The 1-inch diameter and quick-release attachment system make it compatible with QRS-style rotary backup pads. Each disc is sold individually with a minimum order quantity of 10 units.

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 locks diamond securely to the backing for extended service life
• Semi-flexible backing conforms to contours and edges for consistent contact
• Quick-release attachment for fast disc changes on compatible backup pads

Compatibility

Designed for use with QRS-style rotary backup pads accepting 1-inch diameter quick-release abrasive discs. Intended for use on stone, glass, ceramics, carbides, and composite materials.

Installation Notes

Installation and disc changes should be performed with the tool unpowered and disconnected from its power source. Ensure the backup pad is rated for the operating speed of the tool before mounting the disc. Inspect the disc for damage before each use and do not use damaged or delaminated discs. Follow applicable shop safety protocols and wear appropriate eye and hand protection when grinding hard materials.
