3M 7010362339 Abrasive Disc Roll 320 Grit 5 Inch

Product Description

The 3M 7010362339 is a coated abrasive disc roll in the Stikita 426U series, designed for high-production sanding environments where consistent fine finishes are required. Each roll contains multiple 5-inch diameter sanding discs with a 320-grit silicon carbide abrasive on a lightweight A-weight paper backing. The open coat construction and anti-load coating work together to minimize clogging and maintain cut rate over extended use. The Stikita pressure-sensitive adhesive backing allows fast, clean disc changes without leaving residue on the backup pad. This product is configured for vacuum-port sanding systems.

This disc roll is well suited for finish sanding operations on white wood, sealed surfaces, and solid surface materials where surface quality is critical. The flexible A-weight paper backing conforms to backup pad contours, making it effective on flat and mildly contoured workpieces. Common applications include wood shop production lines, cabinetry finishing, drywall feathering, fiberglass prep, and light metal finishing. The 320-grit rating positions this disc in the fine-finishing range, appropriate for sealer sanding between coats or final prep before topcoat application.

Installation Notes

Installation and disc changes should be performed with the sander powered off and unplugged. Align the disc centrally on the backup pad and press firmly to ensure full adhesive contact before operating. Inspect the backup pad surface for debris or residue before attaching each disc to avoid uneven wear. This abrasive is intended for use by finishing professionals and skilled trades in woodworking, construction, and surface preparation applications.
