Merit Abrasives 08834164146 Disc Backing Pad Type S

Product Description

The MERIT ABRASIVES 08834164146 is a Quick-Change Type S disc backing pad designed to hold quick-change abrasive discs in demanding grinding and finishing applications. Fitted with a 0.25 inch shank, it accepts a Power-Lock holder and spins at up to 30,000 RPM, making it suited for die grinders and rotary tools used in metal fabrication, weld blending, and surface prep. Medium density construction provides consistent disc support across a range of material removal tasks. Licensed tradespeople and skilled fabricators working in industrial, maintenance, and job-shop environments are the typical users of this type of backing pad.

This backing pad is used with Quick-Change Type S abrasive discs in applications that include deburring, blending, and surface conditioning on metal, composite, or painted substrates. The Power-Lock holder compatibility makes disc swaps fast without additional tooling, which improves productivity in repetitive finishing operations. It is appropriate for both bench-mounted rotary tools and handheld die grinders commonly found in fabrication shops, maintenance facilities, and industrial service environments.
