Product Description
The MERIT ABRASIVES 08834164651 is a Quick-Change Type S disc backing pad designed to hold quick-change abrasive discs securely during grinding, blending, and surface preparation work. It accepts a Power-Lock holder and is driven by a 0.25 inch shank. Rated to 40,000 maximum RPM, this backing pad suits high-speed die grinders and rotary tools used in metal fabrication, weld cleanup, and finishing operations. Medium density construction provides a balance between conformability and support across the disc face. Fabricators, maintenance technicians, and tool-and-die shops are the primary installers of this type of accessory.
This backing pad is suited for use with Quick-Change Type S abrasive discs in applications requiring rapid disc swaps without removing the pad from the tool. Common use cases include weld seam blending, deburring, surface conditioning on metal substrates, and light stock removal in tight spaces. The Power-Lock compatibility makes it a standard choice in production grinding environments where downtime between disc changes must be minimized.
