Merit Abrasives 08834164038 Disc Backing Pad Quick-change Type R

Product Description

The MERIT ABRASIVES 08834164038 is a Quick-Change Type R disc backing pad designed to mount abrasive discs onto rotary tools and die grinders in metalworking, fabrication, and finishing applications. The pad features a 1/4 inch shank for secure tool chuck engagement and is rated to a maximum of 40,000 RPM, making it suitable for high-speed grinding and surface preparation tasks. Medium density construction provides a balance between conformability and support across flat and moderately contoured workpieces. Licensed tradespeople and shop technicians in metal fabrication, automotive, and maintenance environments typically install and use this component.

This backing pad is suited for use in industrial, commercial, and professional shop environments where quick-change abrasive disc systems are standard. The Power-Lock Type 3 quick-change compatibility allows for rapid disc swaps without additional hardware, reducing downtime during material removal, blending, and finishing operations. It is commonly used with angle grinders, die grinders, and similar rotary tools accepting a 1/4 inch shank. Applications include weld blending, rust removal, deburring, and surface conditioning on metal substrates.
