3M 7100224737 Flexible Diamond Qrs Cloth Disc 10x1 in M74

Product Description

The 3M 7100224737 is a flexible diamond abrasive cloth disc designed for heavy-duty material removal on hard-to-grind substrates including stone, glass, ceramic, metal, carbide, and composites. Built on a QRS hook-and-loop backing, the disc uses a metal-plated bond to securely anchor micron-graded diamonds in an M74 micron pattern configuration. The result is a disc that delivers improved durability under demanding grinding conditions while maintaining a better surface finish without sacrificing cut rates. This product is sold individually and is sized at 10 inches x 1 inches. Licensed tradespeople and fabricators working with advanced materials rely on this disc for consistent, repeatable results.

This disc is suited for both wet and dry grinding applications across industrial fabrication, tool and die, stone fabrication, and composite machining environments. The flexible cloth backing conforms to contoured surfaces, making it practical for work where a rigid disc would lose contact. The M74 micron pattern distributes cutting load evenly across the disc face, which is particularly useful when working on brittle or precision materials like glass and ceramic where surface integrity must be maintained throughout the grinding process.

Key Features

• Metal-plated bond anchors micron-graded diamonds directly to the disc surface for secure, long-lasting abrasive retention
• M74 micron pattern distributes cutting load for a better finish without reducing cut rates
• QRS hook-and-loop backing allows fast disc changes on compatible random orbital and disc tools
• Flexible cloth construction conforms to contoured and irregular workpiece surfaces
• Compatible with hard-to-grind materials including stone, glass, ceramic, carbide, metal, and composites
• Improved durability engineered for demanding, high-cycle grinding applications

Compatibility

Designed for use with QRS hook-and-loop compatible grinding and finishing tools. Suitable for grinding stone, glass, ceramic, metal, carbide, and composite materials in fabrication and finishing applications.

Installation Notes

Installation is performed by fabricators, machinists, or qualified tradespeople using compatible QRS-backing random orbital or disc grinding equipment. Confirm the tool backing pad is clean and free of debris before attaching the disc to ensure full hook-and-loop engagement. Always power down and disconnect the tool from its power source before changing discs. Follow applicable workplace safety standards and wear appropriate personal protective equipment including eye and respiratory protection when grinding stone, ceramic, or carbide materials.
