3M 7100224740 Flexible Diamond Qrs Cloth Disc 10x1in

Product Description

The 3M 7100224740 is a flexible diamond abrasive disc built for heavy-duty grinding and finishing on hard-to-machine materials. Micron-graded diamonds are secured to a hook-and-loop (QRS) backing using a metal-plated bond, which anchors the abrasive firmly and extends disc life under demanding conditions. The result is a disc that maintains cut rates while delivering a better surface finish than conventional abrasives. At 10 inches in diameter with a 1-inch arbor, it is sized for bench or floor grinders used in industrial and trade environments. Installers and fabricators working with difficult materials will find this disc holds up through extended use without rapid degradation.

This disc is suited for grinding, smoothing, and finishing applications on stone, glass, ceramic, metal, carbide, and composite materials. It is commonly used in fabrication shops, tile and stone work, metalworking, and specialty finishing environments where standard abrasives wear too quickly or fail to produce adequate surface quality. The QRS hook-and-loop backing allows for fast disc changes, reducing downtime during production or service work.

Key Features

• Metal-plated bond anchors micron-graded diamonds securely to the backing for extended disc life
• QRS hook-and-loop backing enables fast, tool-free disc changes
• Flexible cloth construction conforms to contoured surfaces during grinding and finishing
• Engineered to maintain cut rates while producing improved surface finish
• Rated for hard-to-grind materials including stone, glass, ceramic, carbide, and composites

Compatibility

Designed as an OEM-style replacement or direct-use diamond abrasive disc for QRS hook-and-loop compatible grinders and finishing tools accepting a 10-inch disc diameter.

Installation Notes

Disc installation and removal should be performed with the grinder powered off and disconnected from its power source. Align the disc squarely on the QRS backing pad before applying pressure to seat the hook-and-loop interface fully. Always confirm the tool RPM rating meets or exceeds the disc rating before operation. Eye protection and appropriate PPE are required when operating abrasive grinding equipment.
