3M 7100070423 Disc Backing Pad Quick-change Type P

Product Description

The 3M 7100070423 is a hard-density disc backing pad designed for use with Quick-Change Type P abrasive discs. It accepts a 1/4-20 female thread attachment and is rated to a maximum of 20,000 RPM, making it suitable for high-speed grinding, blending, and finishing work on metal, composites, and other industrial surfaces. The hard backing density provides consistent support across the disc face, helping maintain flat, even contact during aggressive material removal. This pad is compatible with the Roloc TP quick-change system, allowing fast disc swaps without tools. It is a standard component in metalworking, fabrication, and surface preparation setups used by trade professionals and industrial maintenance technicians.

This backing pad is intended for use with pneumatic and electric right-angle grinders and die grinders equipped with a 1/4-20 threaded spindle. It is commonly used in welding shops, fabrication facilities, maintenance and repair operations, and HVAC or mechanical contracting environments where surface prep work is part of the job. The Quick-Change Type P interface and Roloc TP compatibility make it well suited for production environments where abrasive disc changes need to happen quickly without interrupting workflow.
