3M 7100057886 Abrasive Disc Roll 5 Inch 240 Grit

Product Description

The 3M 7100057886 is a coated abrasive disc roll in the 426U series, designed for high-production sanding environments where consistent finish quality is critical. Each roll contains multiple 5-inch diameter discs with 240-grit silicon carbide abrasive on a lightweight A-weight paper backing. The open-coat construction paired with an anti-load coating minimizes clogging and delivers repeatable results across extended runs. The Stikita pressure-sensitive adhesive backing allows fast disc changes and clean removal, making it well suited for multi-step finishing workflows. Installers and finishing professionals in woodworking, fabrication, and surface prep applications rely on this format for efficiency at the sanding station.

This disc roll is intended for use on vacuum-equipped random orbital or disc sanders in shop and production settings. It performs on white wood, sealed surfaces, solid surface materials, and applications where fine finish control is required. The 240-grit rating positions it for finish and sealer sanding stages rather than aggressive material removal. It is also rated for general-purpose sanding on wood, metal, plastic, drywall, fiberglass, glass, clear coat, and ceramic substrates.

Key Features

• Silicon carbide abrasive with open-coat construction for aggressive cut and reduced loading
• Anti-load coating resists clogging and supports consistent surface finish
• Lightweight A-weight paper backing flexes to conform to backup pad contour
• Stikita PSA backing enables fast attachment and clean removal during multi-step processes
• Roll format supports high-production environments with quick disc access
• Compatible with vacuum sanding systems for dust management

Compatibility

Designed for use with 5-inch vacuum-hole backup pads on disc sanders and random orbital sanders in production finishing and woodworking applications.

Installation Notes

Disc rolls are typically installed and serviced by finishing technicians, woodworkers, or fabrication shop personnel. Before changing discs, power down the sander and allow the spindle to come to a complete stop. Press the disc firmly onto the backup pad to ensure full PSA contact before sanding. Discard discs when loading or finish degradation is observed rather than attempting to clean and reuse.
