3M 7100028467 Psa Disc 8 in 60 Grit Aluminum Oxide 50 Pack

Product Description

The 3M 7100028467 is a pressure-sensitive adhesive (PSA) abrasive disc engineered for use with random orbital sanders in professional surface preparation and finishing applications. The disc measures 8 inches in diameter and cuts with 60-grit aluminum oxide abrasive, placing it in the medium grade range. It features an F-weight paper backing that delivers a balance of flexibility and durability, allowing the disc to conform to workpiece surfaces during aggressive material removal. Each package contains 50 discs. The gold-colored disc is part of the 3M 363I series and is sold in a 50-count package weighing 3.63 pounds.

This disc is suited for metal fabrication shops, woodworking operations, auto body preparation, and general surface conditioning work where a medium-cut abrasive is needed. The PSA backing mounts directly to hook-compatible or PSA sander backing pads without fasteners, making disc changes fast in production environments. The flexible paper construction allows the disc to follow slight contours without loading heavily. No vacuum holes are included, so this disc is intended for use on sanders without dust-extraction port patterns or with a solid backing pad.

Key Features

• 8-inch diameter fits standard large random orbital and disc sanders
• 60-grit aluminum oxide abrasive provides medium-grade, aggressive stock removal
• Pressure-sensitive adhesive backing for fast, tool-free disc mounting
• F-weight paper backing balances flexibility with cut durability
• No vacuum holes — designed for use with solid backing pads
• 50 discs per package for production and high-volume use

Compatibility

Designed for use with random orbital sanders accepting 8-inch PSA backing pads. No vacuum hole pattern is present, so the disc is not compatible with sanders requiring through-hole dust extraction at the disc face.

Installation Notes

Installation is performed by a trained abrasives operator or finishing technician. Before mounting, ensure the sander backing pad is clean and free of adhesive residue from previous discs, as contamination reduces PSA bond strength and can cause disc separation during use. Press the disc firmly onto the backing pad from the center outward to eliminate air pockets. Power down and disconnect the sander from its power source before removing or attaching any disc.
