3M 7100096916 Psa Cloth Disc 348D 1 Inch 50 Grit

Product Description

The 3M 7100096916 is a PSA Cloth Disc in the 348D series, designed for heavy-duty sanding applications across metal, wood, and composite surfaces. It features a pressure-sensitive adhesive backing that bonds securely to a backup pad or steel platen and releases cleanly for fast disc changes. The aluminum oxide abrasive delivers aggressive cut rates and extended service life. A resin bond system shields the abrasive layer from heat buildup, helping the disc last longer under sustained use. This disc is rated for 50 grit material removal at up to 20000 RPM and measures 1 inch in diameter.

The 348D disc suits production grinding, deburring, and finishing tasks in fabrication shops, machine shops, and maintenance environments. Its X-weight cloth backing handles aggressive stock removal without tearing or edge breakdown. The wet and dry compatibility makes it useful on both bench-mounted and portable grinders in situations where coolant or water is present. It is commonly installed by machinists, metalworkers, and finishing technicians who require a consistent, fast-cutting disc on high-speed rotary tools.

Installation Notes

Ensure the grinder or rotary tool is powered off and disconnected before mounting or removing the disc. Confirm the tool's rated RPM meets or exceeds the disc's 20000 RPM rating before use. Clean the backup pad or steel platen surface before applying the PSA backing to ensure full adhesion. Inspect the disc for damage before each use and do not use a disc that shows signs of tearing or separation.
