Merit Abrasives 08834164624 Disc Backing Pad Type S

Product Description

The MERIT ABRASIVES 08834164624 is a Quick-Change Type S disc backing pad designed to hold and drive quick-change abrasive discs in high-speed rotary applications. It features a 0.25 inch shank diameter and a hard density construction, supporting a maximum speed of 30,000 RPM. This backing pad uses a Power-Lock holder interface, providing a secure and repeatable connection during material removal, surface prep, and finishing work. It is installed by trades and technicians who require consistent disc retention and concentricity across demanding grinding or blending tasks.

This backing pad suits applications where quick-change abrasive discs are used for weld blending, deburring, surface conditioning, and light grinding on metal and other hard substrates. Its hard density backing delivers firm disc support, which is appropriate for flat or near-flat surfaces where controlled stock removal is required. The Power-Lock compatibility makes it well-suited for use with standard quick-change arbors and handheld pneumatic or electric die grinders.
