3M 7010307631 Psa Disc Roll 763U 5 Inch P100 Grit

Product Description

The 3M 7010307631 is the Stikita Paper Disc Roll 763U, a coated abrasive disc roll designed for aggressive material removal in woodworking, paint preparation, and metal finishing applications. Built on a heavy F-weight paper backing, each 5-inch diameter disc delivers the rigidity needed for heavy-duty sanding while resisting tearing under load. The P100 grit ceramic aluminum oxide blend is self-sharpening, extending disc life and maintaining consistent cut rates across the work surface. A pressure-sensitive adhesive (PSA) backing allows fast, clean attachment and removal from compatible Stikita disc pads. This product is installed and used by woodworkers, painters, metal fabricators, and general contractors.

The 763U disc roll is suited for residential and light commercial finishing work where frequent disc changes and material versatility are priorities. The PSA backing eliminates the need for hook-and-loop systems, making it a practical choice on rotary tools and random orbital sanders. Typical applications include bare wood sanding, paint scuff sanding between coats, and light deburring or surface conditioning on metal. The roll format reduces per-disc cost and limits packaging waste compared to individually packaged discs.

Key Features

Compatibility

Designed for use with 3M Stikita disc pads and standard 5-inch PSA-style disc pads on rotary tools and random orbital sanders.

Installation Notes

Ensure the disc pad surface is clean and free of debris before applying each disc to achieve full PSA contact and secure adhesion. Power down and disconnect the sander from its power source before changing discs. Align the disc centered on the pad before pressing firmly to seat the adhesive. Remove used discs by peeling from the edge to avoid adhesive residue transfer to the pad face.
