3M 7010307661 Flexible Diamond Qrs Cloth Sheet

Product Description

The 3M 7010307661 is a flexible diamond abrasive cloth sheet designed for precision material removal on hard-to-grind surfaces. It uses micron-graded diamond abrasive particles anchored by a metal-plated bond to a QRS hook-and-loop backing. The M250 micron grade balances cut rate and finish quality, making it suitable for work on stone, glass, ceramic, metal, carbide, and composite materials. At 2.25 inches by 5 inches, it fits standard QRS-compatible random orbital and hand-sanding tools. Licensed HVAC technicians, machinists, and fabricators working with hard or brittle materials reach for this sheet when conventional abrasives fail to perform.

This diamond cloth sheet is used in applications where surface finish and dimensional accuracy matter. It performs on flat or contoured surfaces and handles materials that quickly wear conventional aluminum oxide or silicon carbide abrasives. Typical use cases include lapping valve seats, finishing ceramic or glass components, deburring carbide tooling, and surface preparation on composite panels. The QRS backing allows fast pad changes in production or field service environments.

Key Features

• Metal-plated bond securely anchors micron-graded diamonds to the backing for consistent cut and long service life
• M250 micron grade delivers a refined finish without sacrificing material removal rates
• QRS hook-and-loop backing enables tool-free sheet changes on compatible sanders
• Flexible cloth construction conforms to contoured or irregular workpiece surfaces
• Compatible with hard-to-grind materials including stone, glass, ceramic, metal, carbide, and composites

Compatibility

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

Installation Notes

Attach the sheet to a clean, dry QRS-compatible backup pad before use. Inspect the hook-and-loop interface before each use to confirm full engagement and prevent sheet slippage during operation. When working with glass, ceramic, or carbide, use light, consistent pressure to avoid chipping or cracking the workpiece. Follow applicable workplace safety standards for abrasive operations, including eye protection and dust control.
