Product Description

The MERIT ABRASIVES 08834164949 is a Quick-Change Type R disc backing pad designed to hold and drive quick-change abrasive discs in rotary grinding and finishing applications. Featuring a 0.25 inch shank diameter and a rated maximum speed of 20,000 RPM, this backing pad is built for use with pneumatic or electric die grinders and right-angle grinders. The medium-density construction helps distribute pressure evenly across the abrasive disc surface, supporting consistent material removal and finish quality. This pad is compatible with Power-Lock Type 3 quick-change disc systems, allowing for fast disc swaps without tools.

This backing pad is suited for metal fabrication, weld blending, deburring, and surface preparation tasks in both shop and field environments. It is a standard tool in the kits of metal workers, pipefitters, ironworkers, and general maintenance technicians who rely on quick-change abrasive systems for efficiency. The 0.25 inch shank fits the collets found on most standard die grinders used in industrial and trade settings.
