Standard Abrasives 7000121728 Disc Backing Pad Type R

Product Description

The STANDARD ABRASIVES 7000121728 is a Quick-Change Type R disc backing pad designed to mount and secure quick-change abrasive discs for grinding, blending, and finishing applications. It features a 0.25 inch shank for use with pneumatic or electric right-angle die grinders and is rated to a maximum of 40,000 RPM. The medium-density construction provides consistent backing support across the disc face during material removal. Fabricators, metal finishers, and maintenance technicians typically install and operate this pad as part of a quick-change abrasive disc system.

This backing pad is suited for use in metal fabrication shops, automotive body work, and general surface preparation tasks where rapid disc changes are required. The Type R quick-change interface allows abrasive discs to be swapped without additional tooling, reducing downtime during production or field service operations. It is appropriate for both light-duty and medium-duty finishing work on ferrous and non-ferrous substrates.

Installation Notes

Installation is typically performed by fabricators or maintenance technicians using a standard die grinder with a 0.25 inch collet. Ensure the grinder is fully powered off and air supply is disconnected before mounting or removing the backing pad. Do not exceed the 40,000 RPM maximum speed rating of the pad. Verify that the mating abrasive disc is also rated for the operating RPM before use.
