Merit Abrasives 08834167095 Quick-change Disc 50 Grit 1 Inch

Product Description

The MERIT ABRASIVES 08834167095 is a coated quick-change abrasive disc engineered for use with Power-Lock Type R attachment systems. Measuring 1 inch in diameter, this disc uses zirconia alumina as its abrasive material, a tough, self-sharpening grain well suited to aggressive metal grinding, blending, and surface preparation. The polyester backing is rated Rigid and classified as Y-weight, providing firm support during high-speed operation. With a maximum speed rating of 40,000 RPM, this disc is designed for small right-angle grinders and die grinders used in fabrication, weld prep, and finishing applications.

This disc is intended for use in metal fabrication shops, maintenance and repair operations, and light manufacturing environments where small-diameter quick-change discs are required. The 50-grit coarse grade makes it effective for rapid stock removal on steel, stainless steel, and other hard metals. It is commonly used by welders, pipefitters, ironworkers, and general maintenance technicians who need a compact, fast-cutting disc for tight spaces or contoured surfaces.

Installation Notes

Installation and disc changes should be performed with the grinder powered off and disconnected from its power source. Ensure the mandrel type matches the Type R attachment system before mounting. Always verify the tool's rated RPM does not exceed the disc's 40,000 RPM maximum before operation. Inspect the disc for damage or delamination prior to each use and discard any disc showing visible defects.
