3M 7010364839 Abrasive Disc Roll 6 Inch P500 Grit

Product Description

The 3M 7010364839 is a Stikita 360L coated abrasive disc roll designed for fine finishing work on plastics, gel coats, and polyurethane solid surface substrates. Built with aluminum oxide abrasive grain on a durable film backing, this disc roll delivers a consistent, close-tolerance finish across a range of surface preparation and finishing applications. At P500 grit, it is well-suited for final sanding passes where surface smoothness is critical. The Stikita pressure-sensitive adhesive backing allows fast disc application and clean removal without leaving residue. Each roll eliminates the need to peel individual disc liners, keeping workflow efficient on the job.

This disc roll is used in automotive refinishing, marine gel coat finishing, composite fabrication, and solid surface work where fine-grit film-backed abrasives are specified. The 6-inch diameter fits standard random orbital and DA sanders equipped with hook-and-loop or PSA backup pads. Open coat construction reduces loading when working with softer materials such as plastics and cured polyurethane, maintaining cut rate over extended use. This product is sold by the roll with a minimum order quantity of 4 rolls.

Compatibility

Designed for use with 6-inch PSA backup pads on random orbital and dual-action sanders commonly used in automotive, marine, and solid surface finishing applications.

Installation Notes

Mounting and removal should be performed with the sander powered off and disconnected from any power source. Ensure the backup pad surface is clean and free of debris before applying each disc to maintain full PSA contact. Discs should be seated firmly and evenly on the pad before operating the tool. Follow applicable shop safety practices and equipment manufacturer guidelines when operating pneumatic or electric orbital sanders.
