3M 7010298831 Flexible Diamond Qrs Cloth Sheet M74

Product Description

The 3M 7010298831 is a flexible diamond abrasive cloth sheet designed for precision grinding and finishing on hard-to-work materials. It features micron-graded diamonds anchored in a metal-plated bond to a QRS hook-and-loop backing, which allows fast sheet changes without tools. Measuring 2.25 inches x 5 inches and rated at M74 micron, this sheet delivers consistent surface finishes while maintaining competitive cut rates. It is used by machinists, fabricators, and finishing technicians who require repeatable results on demanding substrates.

This abrasive sheet is suited for applications involving stone, glass, ceramic, hardened metal, carbide, and composite materials. The hook-and-loop QRS backing makes it compatible with palm-style and random-orbit sanders equipped with matching hook-and-loop pads. It is commonly used in shop and field finishing operations where conventional abrasives wear too quickly or leave inconsistent surface textures on hard substrates.

Key Features

• M74 micron diamond grading for precise, controlled material removal
• Metal-plated bond securely anchors diamond abrasive to the backing
• QRS hook-and-loop backing enables tool-free sheet changes
• Flexible cloth construction conforms to contoured and flat surfaces
• Suitable for stone, glass, ceramic, metal, carbide, and composites

Compatibility

Designed for use with QRS hook-and-loop sanding tools and backup pads accepting 2.25-inch x 5-inch abrasive sheets.

Installation Notes

Attach the sheet firmly to a compatible QRS hook-and-loop backup pad before operating. Ensure the sander or tool is powered off before mounting or removing the sheet. Use appropriate eye protection and respiratory equipment when grinding glass, ceramic, or composite materials, as fine particulate dust is generated. Follow applicable workplace safety regulations for abrasive tool use.
