3M 7000118910 Psa Cloth Disc 348D P120 Grit 1/2 Inch Ao

Product Description

The 3M 7000118910 is a pressure-sensitive adhesive (PSA) cloth sanding disc in the 348D series, designed for heavy-duty material removal in professional finishing and fabrication applications. Measuring 1/2 inch in diameter with a P120 grit rating, this disc uses aluminum oxide abrasive bonded with a resin system that resists heat buildup, extending disc life under sustained use. The X-weight cloth backing handles aggressive stock removal without tearing or edge fraying. Licensed trades and shop professionals in metal fabrication, woodworking, and surface prep rely on this disc format for consistent cut rates across multiple substrate types.

This disc is suited for both wet and dry sanding applications on metal, wood, and composite surfaces. The PSA backing attaches directly to compatible backup pads or steel platens, allowing fast disc swaps without adhesive residue buildup. It is rated for operation up to 20,000 RPM, making it compatible with high-speed inline and right-angle tools used in production and maintenance environments. Minimum order quantity for this SKU is 500 units, positioning it as a production consumable rather than a one-off replacement.

Compatibility

Designed for use with PSA-compatible backup pads and steel platens on high-speed rotary finishing and grinding tools rated to 20,000 RPM or higher.

Installation Notes

Disc installation and removal should be performed with the tool powered off and disconnected from its power source. Confirm the backup pad or platen surface is clean and free of adhesive residue before applying a new disc to ensure full contact and secure adhesion. Do not exceed the 20,000 RPM maximum speed rating. Inspect the disc for tears or edge damage before each use and discard any damaged discs.
