3M 7010308395 Psa Cloth Sanding Disc 40 Grit 10 Inch

Product Description

The 3M 7010308395 is a PSA cloth sanding disc designed for heavy-duty material removal in industrial and trade applications. The disc uses an aluminum oxide abrasive bonded with a resin system that resists heat buildup, extending disc life under sustained cutting loads. A pressure-sensitive adhesive backing lets the disc mount quickly to a backup pad or steel platen and peel off cleanly when it's time for replacement. The X-weight cloth backing handles aggressive stock removal without tearing or edge breakdown. Rated for use at up to 4000 RPM, this 10-inch disc is suited for both wet and dry sanding operations.

This disc is used in metalworking, fabrication, and surface preparation tasks where consistent, fast cutting is required. The 40-grit aluminum oxide construction makes it appropriate for aggressive grinding, weld blending, and surface conditioning on metal, wood, and composite materials. Installers and fabricators in production shops, maintenance environments, and field service applications will find the PSA mount system practical for high-volume disc changes on large-diameter rotary tools and stationary platens.

Key Features

• Pressure-sensitive adhesive backing adheres firmly to backup pads and steel platens, then releases cleanly for fast disc changes
• X-weight cloth backing resists tearing and edge wear under aggressive cutting loads
• Aluminum oxide abrasive delivers fast cut rates and long service life across a range of surfaces
• Resin bond guards against heat damage, preserving abrasive performance over extended use
• Rated for wet and dry applications, adding flexibility across job types
• 4000 RPM maximum speed rating suits large rotary disc tools and sanding machines

Compatibility

Designed as an OEM-style replacement or direct-use PSA disc for 10-inch backup pads and steel platens on rotary disc grinders and stationary sanding machines that accept PSA-mount abrasives.

Installation Notes

This disc is installed and serviced by metalworkers, fabricators, and maintenance technicians. Before mounting, ensure the backup pad or platen surface is clean and free of adhesive residue from the previous disc. Do not exceed the 4000 RPM maximum speed rating. Verify the spindle and mounting hardware are secure and the machine is powered off before changing discs.
