3M 7100027049 Flexible Diamond Qrs Cloth Disc 1 in

Product Description

The 3M 7100027049 is a flexible diamond quick-release (QRS) cloth disc engineered for grinding hard-to-machine materials that conventional abrasives struggle with. At 1 inch in diameter, this disc uses micron-graded diamond mineral bonded with a metal bond matrix to deliver aggressive, consistent cutting action on stone, glass, ceramics, carbides, and composites. The semi-flexible cloth backing allows the disc to conform to edges and contours, making it useful beyond flat-surface work. Weighing just 0.02 pounds, it is a compact, single-use-style abrasive suited for precision material removal tasks.

This disc is designed for use in applications where surface finish consistency and aggressive cut rate on hard or brittle materials are both required. Typical scenarios include toolroom work, precision grinding of ceramic or carbide components, glass finishing, and composite part preparation. The quick-release attachment system allows fast disc changes, reducing downtime during production or service work. The open dot mineral pattern prevents swarf and debris from packing the disc surface, extending usable life between changes.

Key Features

• Micron-graded diamond mineral delivers aggressive cut and consistent scratch pattern on hard-to-grind materials
• Open dot mineral pattern allows swarf and debris to escape, reducing loading during use
• Metal bond securely anchors diamond particles for durable, repeatable performance
• Semi-flexible cloth backing conforms to edges and contoured surfaces
• Quick-release (QRS) attachment enables fast, tool-free disc changes

Compatibility

Designed for use with quick-release (QRS) compatible random orbital or disc grinding tools. Suitable for grinding and finishing stone, glass, ceramics, carbides, and composite materials.

Installation Notes

Installation and disc changes should be performed by qualified technicians or skilled tradespeople familiar with abrasive tooling. Ensure the host tool is powered off and fully stopped before mounting or removing the disc. Verify the tool spindle speed rating does not exceed the maximum rated speed of the disc. Follow all applicable workplace safety standards and wear appropriate PPE including eye and face protection when operating abrasive equipment.
