Merit Abrasives 08834164037 Disc Backing Pad Quick-change Type R

Product Description

The MERIT ABRASIVES 08834164037 is a Quick-Change Type R disc backing pad designed for use with rotary power tools in metal fabrication, weld blending, and surface preparation applications. The pad accepts a 0.25 inch shank and is rated to a maximum of 40,000 RPM, making it suitable for high-speed grinding and finishing work. Medium density construction provides consistent disc support and controlled material removal. It is compatible with Power-Lock Type 3 quick-change disc systems, allowing fast disc swaps without additional hardware. This backing pad is typically installed and used by metal fabricators, welders, maintenance technicians, and industrial tradespeople working with angle grinders or die grinders.

This backing pad is suited for use with quick-change abrasive discs in both shop and field environments. Common applications include deburring, rust removal, surface blending, and prep work on steel, aluminum, and other metals. The quick-change interface reduces tool downtime during disc changes, which is especially useful in production or repair workflows where multiple grits are cycled through in sequence. It fits standard die grinders and right-angle tools equipped with a 0.25 inch collet.
