3M 7000144099 Abrasive Disc Roll 400 Grit 5 Inch

Product Description

The 3M 7000144099 is a Stikita 426U coated abrasive disc roll designed for high-production sanding environments where consistent finish quality is critical. Each roll packages multiple 5-inch diameter discs with a pressure-sensitive Stikita adhesive backing for fast attachment and clean removal between finishing steps. The abrasive is silicon carbide at 400 grit, carried on a lightweight A-weight paper backing. An anti-load coating combined with open coat construction keeps the disc cutting freely and reduces material buildup during extended use. This product is suited for finish sanding work in wood shops, cabinet shops, and production finishing lines.

The 426U disc roll is intended for sanding applications where a fine finish is required. It performs on white wood, sealed surfaces, and solid surface materials, and is also effective on metal, plastic, drywall, fiberglass, glass, clear coat, and ceramic. The open coat structure provides aggressive cut without loading, making it a practical choice for multi-step finishing processes where discs are changed frequently. The roll format reduces handling time and supports high-volume work.

Installation Notes

Apply and remove disc from backup pad by hand — no tools required. Ensure the backup pad surface is clean and free of debris before attaching the disc to maintain proper adhesion. Operate at speeds appropriate for the backup pad and grinder manufacturer specifications. Discard discs that show signs of loading, tearing, or uneven wear.
