3M 7000118920 Psa Cloth Sanding Disc 40 Grit 2 Inch

Product Description

The 3M 7000118920 is a pressure-sensitive adhesive (PSA) cloth sanding disc designed for heavy-duty material removal in professional and industrial applications. Built on an X-weight cloth backing, this 2-inch diameter disc uses aluminum oxide abrasive bonded with a resin system to cut aggressively and resist heat buildup. Rated to 15000 RPM, it is suitable for both wet and dry use. The PSA backing adheres firmly to a backup pad or steel platen and releases cleanly, making disc changes fast and efficient on the shop floor or job site.

This disc is suited for metalworking, fabrication, woodworking, and general surface preparation tasks where a compact 2-inch disc is required. The 40-grit cut level makes it appropriate for aggressive stock removal, weld blending, and rough shaping on metal, wood, and composite surfaces. Trades including pipefitters, welders, millwrights, and general contractors commonly use PSA discs of this type in angle grinders and random orbital tools fitted with a compatible backup pad or steel platen.

Key Features

• PSA backing adheres to backup pads or steel platens and releases cleanly for fast replacement
• X-weight cloth backing resists tearing and edge wear under aggressive use
• Aluminum oxide abrasive delivers fast cut and long service life across a wide range of materials
• Resin bond protects abrasive layer from heat damage to extend disc life
• Rated for wet and dry applications
• 15000 RPM maximum operating speed

Compatibility

Designed for use with backup pads and steel platens that accept 2-inch PSA-mount sanding discs at up to 15000 RPM.

Installation Notes

Mounting and removal should be performed with the tool unplugged or the air supply disconnected and the disc at a complete stop. Confirm that the backup pad or steel platen is rated at or above the maximum RPM of the disc before mounting. Do not exceed the 15000 RPM rated speed. Inspect the disc for damage before each use and discard any disc showing tears, edge fraying, or adhesive failure.
