3M 7010363766 Hook Loop Disc 400 Grit 3 in Diamond

Product Description

The 3M 7010363766 is a 3-inch hook and loop abrasive disc designed for precision surface finishing on hard materials. Part of the 3M 6002J series, it uses a diamond abrasive on a flexible cloth backing, making it well-suited for controlled material removal on hardened steel, carbide, ceramics, glass, and stone. Rated at 400 grit (40-micron grit size), it falls in the super fine grade range, targeting finish work and light stock removal rather than aggressive cutting. The hook and loop attachment system allows fast disc swaps without adhesive, reducing changeover time during extended use.

This disc is intended for use with compatible 3-inch hook and loop backup pads on angle grinders, rotary tools, or random-orbit sanders. The super fine 400 grit makes it appropriate for final-stage finishing passes on hard, brittle, or sensitive workpiece materials where surface finish quality is critical. The flexible cloth backing conforms to mild contours, giving it utility in both flat and slightly curved surface applications. No vacuum holes are included, so it is suited to open-air grinding setups rather than dust-extraction platforms.

Key Features

• Diamond abrasive construction for cutting hardened, brittle, and high-density materials
• 400 grit super fine grade for finish-stage stock removal and surface refinement
• Flexible cloth backing conforms to mild surface contours
• Hook and loop attachment for tool-free disc changes
• 3-inch diameter fits standard small-format backup pads
• No vacuum holes — suited to open-air grinding applications

Compatibility

Designed for use with 3-inch hook and loop backup pads on rotary grinders, angle grinders, and random-orbit sanders that accept this disc format. No specific compatible model numbers were provided by the manufacturer for this listing.

Installation Notes

Mount the disc onto a clean, dry hook and loop backup pad, ensuring full surface contact before operating. Inspect the pad face for debris or worn hooks that could cause the disc to release during use. Always wear appropriate eye and hand protection when grinding or finishing hard materials. Follow applicable workplace safety standards for abrasive wheel and disc use.
