3M 7000148149 Psa Cloth Disc 348D 6 Inch 36 Grit Ao

Product Description

The 3M 7000148149 is a PSA cloth sanding disc in the 348D series, designed for heavy-duty material removal in industrial and trade finishing applications. The disc uses aluminum oxide abrasive bonded with a resin bond system that resists heat buildup and extends disc life. A pressure-sensitive adhesive backing mounts directly to a backup pad or steel platen without fasteners, allowing fast disc swaps during high-volume work. At 6 inches in diameter and 36 grit, it is suited for aggressive stock removal on metal, wood, and composite surfaces. Maximum operating speed is 12,000 rpm.

This disc is built for fabricators, metal finishers, woodworkers, and production shop technicians who run high-cycle sanding operations. The X-weight cloth backing resists tearing and edge wear under sustained pressure, making it appropriate for both flat and contoured surface work. It supports wet and dry sanding, giving operators flexibility across different finishing environments and coolant requirements.

Compatibility

Designed for use with backup pads and steel platens that accept 6 inch PSA-mount sanding discs at speeds up to 12,000 rpm.

Installation Notes

Installation is performed by trade finishers and fabricators familiar with angle grinders, random orbital sanders, and disc sanding machines. Verify the backup pad or platen is clean and free of debris before applying the PSA backing to ensure full adhesion. Confirm the tool's rated speed does not exceed 12,000 rpm before mounting. Worn or contaminated platens should be replaced before disc installation to prevent uneven contact and premature disc failure.
