3M 7100094711 Flexible Diamond Qrs Cloth Sheet M40

Product Description

The 3M 7100094711 is a flexible diamond abrasive cloth sheet designed for precision surface finishing on hard-to-grind materials. It measures 2.75 inches x 5 inches and uses an M40 micron-graded diamond pattern, delivering consistent material removal with a fine finish. The diamonds are anchored to the backing with a metal-plated bond, which holds abrasive particles firmly in place during use. This sheet is engineered to produce better surface finishes without a significant drop in cut rate, making it a reliable choice for detail work on demanding substrates. It is used by machinists, tool and die makers, and skilled tradespeople working with precision materials.

This sheet is suited for grinding and finishing hard materials including stone, glass, ceramic, metal, carbide, and composite substrates. The QRS backing uses a hook-and-loop attachment system, allowing quick sheet changes on compatible random orbital and detail sanders. Pattern 18 refers to the abrasive layout configuration. The M40 micron designation indicates a fine grit level appropriate for finishing and light stock removal rather than aggressive shaping. Applications include precision tooling, mold finishing, lapidary work, and surface prep on hard engineered materials.

Key Features

• M40 micron-graded diamonds provide consistent, fine-grit abrasion on hard substrates
• Metal-plated bond securely anchors diamonds to the backing for extended service life
• QRS hook-and-loop backing enables fast sheet changes on compatible tools
• Flexible cloth construction conforms to contoured and irregular surfaces
• Effective on stone, glass, ceramic, metal, carbide, and composites

Compatibility

Designed for use with QRS hook-and-loop compatible random orbital and detail sanders. Verify tool compatibility with the 2.75-inch x 5-inch sheet size before installation.

Installation Notes

Installation requires a compatible QRS hook-and-loop backing pad. Power down and disconnect the tool from its power source before attaching or removing abrasive sheets. Ensure the sheet seats flat and fully engages the hook-and-loop interface before resuming operation. Inspect the sheet and backing pad regularly for wear or debris buildup that could affect adhesion.
