3M 7100052511 Flexible Diamond Qrs Cloth Disc 1.5 in

Product Description

The 3M 7100052511 is a flexible diamond abrasive disc designed for cutting and finishing hard-to-grind materials that conventional abrasives struggle to handle. Built on a semi-flexible cloth backing, the disc uses micron-graded diamond mineral bonded with a metal bond system for consistent scratch patterns and aggressive material removal. At 1.5 inches in diameter, it mounts via a quick-release attachment system, making it practical for high-frequency swap-outs during production or finishing work. This disc is suited for skilled trades and fabrication professionals working with stone, glass, ceramics, carbides, and composite materials.

This disc is used in grinding, shaping, and surface finishing applications where material hardness or brittleness rules out conventional abrasive options. The semi-flexible backing allows the disc to conform to edges and contoured surfaces, making it effective for detail work on curved or irregular profiles. It is commonly used in fabrication shops, precision machining environments, and specialty trade applications where consistent scratch pattern and controlled material removal are required.

Key Features

• Micron-graded diamond mineral delivers aggressive cut and repeatable scratch pattern on hard materials
• Metal bond system anchors diamond securely for extended service life
• Open dot mineral pattern allows swarf and debris to escape, reducing loading
• Semi-flexible cloth backing conforms to contours and edges
• Quick-release attachment for fast disc changes
• Compatible with hard-to-grind substrates including stone, glass, ceramics, carbides, and composites

Compatibility

Designed for use with quick-release (QRS) compatible random orbital and finishing tool systems; suited for grinding and finishing applications on stone, glass, ceramic, carbide, and composite materials.

Installation Notes

Installation and use of abrasive discs should follow the tool manufacturer's RPM rating — never exceed the disc's maximum rated speed. Ensure the tool is powered off and unplugged before mounting or removing the disc. Proper personal protective equipment including eye protection and respiratory protection is recommended when grinding ceramics, carbides, or composite materials. Confirm the quick-release attachment is fully seated before operating.
