3M 7100064887 Abrasive Disc Roll 5 Inch P320 Grit Film

Product Description

The 3M 7100064887 is an abrasive disc roll featuring aluminum oxide grain on a film backing, designed for fast cut rates and uniform, close-tolerance finishes. The Stikita pressure-sensitive adhesive backing allows quick application and clean removal from random orbital sanders and similar tools. At P320 grit, this disc is suited for fine sanding stages including paint preparation, defect repair, and finish sanding on wood and painted surfaces. The open coat construction combined with a load-resistant coating helps prevent loading from dust and debris, extending disc life in high-production work environments. The roll form eliminates individual disc liners, speeding up disc changes on the job.

This disc roll is used in automotive refinishing, woodworking, and general surface prep applications where a consistent, fine finish is required. The 5 inch diameter fits standard 5 inch random orbital and DA sanders equipped with hook-and-loop or Stikita-compatible backup pads. The film backing provides greater tear resistance compared to paper-backed alternatives, making it appropriate for production environments where durability and finish consistency are priorities. The roll format is particularly efficient for shops cycling through high disc volumes.

Key Features

Compatibility

Designed for use with 5 inch random orbital and dual-action sanders equipped with Stikita or pressure-sensitive adhesive compatible backup pads.

Installation Notes

Disc application and removal should be performed with the sander powered off and disconnected from air or electrical supply. Press the disc firmly onto the backup pad to ensure full adhesive contact before use. Inspect the backup pad surface for contamination or wear before attaching a new disc, as an uneven pad surface can affect finish quality and disc life.
