Merit Abrasives 66254420824 Scrubber Buffing Wheel 4in

Product Description

The MERIT ABRASIVES 66254420824 is a mounted scrubber buffing wheel designed for surface finishing, light deburring, and blending applications in metalworking and fabrication environments. The wheel measures 4 inches in diameter with a 1/4 inch shank for direct mounting to die grinders, drill presses, or rotary tools. Constructed from aluminum oxide abrasive in a 2-ply scrubber configuration, it carries a very fine grade designation and a medium wheel density, delivering consistent scratch patterns and controlled material removal without aggressive stock loss. Maximum operating speed is 6,000 RPM.

This mounted buffing wheel suits surface prep and finishing work on ferrous and non-ferrous metals, composites, and painted surfaces. It is commonly used in fabrication shops, maintenance environments, and production lines where operators need to blend welds, smooth machined surfaces, or prepare substrates before coating. The 1/4 inch shank makes it compatible with standard die grinders and handheld rotary tools widely used by machinists, pipefitters, and sheet metal workers.

Installation Notes

Installation is performed by machinists, fabricators, or maintenance technicians using a standard die grinder or rotary tool with a compatible 1/4 inch collet. Always verify the tool's rated RPM meets or exceeds the wheel's 6,000 RPM maximum before mounting. Secure the shank fully in the collet and tighten per the tool manufacturer's specification before operating. Wear appropriate eye protection and ensure all guards are in place before starting the tool.
