Merit Abrasives 08834164643 Disc Backing Pad Type R

Product Description

The MERIT ABRASIVES 08834164643 is a quick-change disc backing pad designed to mount and secure abrasive discs in grinding and finishing applications. Built on a Type R quick-change platform with Power-Lock Type 3 compatibility, it accepts a 0.25-inch shank and is rated to a maximum of 30,000 RPM. The hard-density backing pad provides a firm, stable support surface, which helps maintain consistent abrasive contact and controlled material removal. This pad is installed by metalworkers, fabricators, and maintenance technicians working with die grinders and similar rotary tools in both shop and field environments.

This backing pad suits surface preparation, weld blending, deburring, and finishing tasks where quick disc changes are required to maintain workflow efficiency. The Type R quick-change system allows operators to swap abrasive discs without additional tools, reducing downtime between disc changes. It is appropriate for use on metal, ferrous and non-ferrous alike, in production and MRO settings where repeated abrasive disc mounting is part of the routine.
