Product Description

The MERIT ABRASIVES 08834164005 is a disc backing pad designed for use with quick-change abrasive discs in grinding, blending, and surface preparation applications. It accepts a Power-Lock Type 1 quick-change disc system and features a 0.25 inch shank for compatibility with standard die grinders and right-angle grinders. Rated to a maximum of 20,000 RPM, it delivers stable disc support at high speeds. Medium density construction balances flexibility and support across a range of material removal and finishing tasks. This backing pad is a direct component for professionals performing weld dressing, deburring, or surface conditioning work in fabrication, metalworking, or maintenance environments.

This backing pad is suited for use in industrial and trade settings where quick-change disc systems are standard. It is commonly installed on die grinders and pneumatic or electric right-angle grinders used by metal fabricators, pipefitters, welders, and maintenance technicians. The Power-Lock Type 1 quick-change compatibility allows for fast disc swaps without tools, reducing downtime during multi-step surface prep operations. Typical applications include weld seam blending, light stock removal, and surface conditioning on ferrous and non-ferrous metals.
