3M 7010309455 Diamond Psa Cloth Disc 8 Inch 7100 Rpm

Product Description

The 3M 7010309455 is a flexible diamond PSA cloth disc engineered for grinding and finishing on hard-to-machine materials. Designated as the 6008J, it uses diamond mineral abrasive bonded to a durable cloth backing that holds up under aggressive stock removal. The disc measures 8 inches in diameter and is rated to 7,100 RPM, making it suitable for both bench and portable disc grinder applications. An open dot pattern across the face allows swarf and fine debris to clear the cutting surface during use, which reduces loading and extends the working life of the disc. The PSA backing adheres directly to compatible disc pads for fast tool attachment with no hardware required.

This disc is designed for use on stone, glass, ceramic, metal, carbide, and composite materials where conventional abrasives lose effectiveness quickly. It is available in three dot patterns to match different finishing requirements and surface-contact needs. The backing is compatible with wet grinding setups, so it can be run with coolant to manage heat and prolong disc life on heat-sensitive workpieces. Typical users include fabricators, tool-and-die shops, stone and tile contractors, and industrial maintenance technicians working with hard or abrasion-resistant substrates.

Key Features

• Diamond mineral abrasive handles stone, glass, ceramic, metal, carbide, and composites

Installation Notes

Verify that the grinder or disc pad is clean and free of debris before applying the PSA backing to ensure a secure bond. Confirm the tool's maximum operating speed does not exceed 7,100 RPM before mounting the disc. Power down and disconnect the tool from its power source before changing discs. Inspect the disc and backing for damage before each use and discard any disc showing cuts, tears, or delamination.
