Merit Abrasives 08834161174 Quick-change Type R Backing Pad

Product Description

The MERIT ABRASIVES 08834161174 is a Quick-Change Type R disc backing pad designed to mount abrasive discs on pneumatic and electric grinders and die grinders. It accepts Power-Lock Type 3 quick-change discs and spins up to 30,000 RPM, making it well suited for metal finishing, weld blending, and surface preparation tasks. The 0.25 inch shank fits standard collet chucks found on most die grinders. Medium density construction provides consistent disc support without excessive flex during use. This pad is installed and used by metal fabricators, maintenance technicians, and pipefitters who rely on quick-change abrasive systems for efficiency on the job.

This backing pad is intended for use with quick-change abrasive discs in light- to medium-duty grinding and finishing applications. It fits die grinders commonly used in fabrication shops, field maintenance, and pipework. The quick-change design allows fast disc swaps without additional tools, reducing downtime during multi-step surface work. It is appropriate for use on metal, weld seams, and similar hard surfaces where a compact grinding tool is required.
