3M 7100028400 Psa Cloth Disc 348D 15 Inch 80 Grit Ao

Product Description

The 3M 7100028400 is a PSA cloth sanding disc in the 348D series, designed for heavy-duty material removal on metal, wood, and composite surfaces. The disc measures 15 inches in diameter and cuts with 80-grit aluminum oxide abrasive, making it well suited for aggressive stock removal and surface preparation tasks. A pressure-sensitive adhesive backing bonds firmly to a backup pad or steel platen and releases cleanly for fast disc changes. This disc is used by metalworkers, fabricators, and finishing technicians running large-diameter disc sanders in production or job-shop environments.

The 348D disc fits large stationary and portable disc sanders that accept 15-inch PSA-mount abrasives. It is suited for both wet and dry sanding operations, covering applications from weld blending and rust removal to shaping and leveling on ferrous and non-ferrous metals as well as wood substrates. The 80-grit cut level targets initial material removal and surface leveling rather than finish sanding.

Key Features

• Pressure-sensitive adhesive backing adheres securely to backup pads or steel platens and releases cleanly for quick replacement
• X-weight cloth backing withstands aggressive cutting without tearing or edge breakdown
• Aluminum oxide abrasive delivers fast cutting speed and extended service life across a range of surfaces
• Resin bond system dissipates heat to protect the abrasive layer and extend disc life
• Compatible with wet and dry sanding applications

Compatibility

Designed as a PSA-mount replacement disc for large-diameter disc sanders and steel platens accepting 15-inch pressure-sensitive adhesive abrasive discs.

Installation Notes

Installation is performed by abrasive equipment operators and finishing technicians. Before mounting, power down and lock out the sander per standard LOTO procedures. Ensure the backup pad or steel platen face is clean and free of debris before pressing the disc into place to achieve full adhesive contact. Do not exceed the maximum RPM rating of the machine or the disc.
