Merit Abrasives 08834137473 Mounted Flap Wheel 180 Grit

Product Description

The MERIT ABRASIVES 08834137473 is a mounted flap wheel designed for precision surface finishing, deburring, and blending in tight or contoured areas. Built with aluminum oxide coated abrasive on a cloth backing, this wheel delivers consistent cut and finish across its service life. It measures 3/8 inch in diameter with a 3/8 inch face width and runs on a 1/8 inch shank, making it a natural fit for die grinders, rotary tools, and similar handheld power tools. Rated to 40,000 RPM maximum, it is suited for fine detail work where surface quality matters. The 180 grit very fine grade targets light stock removal, finishing passes, and surface preparation before coating or inspection.

This mounted flap wheel is used in metal fabrication, tool and die, maintenance, and general metalworking applications where access to bores, slots, contours, and irregular profiles is required. Its compact diameter allows it to reach areas that larger grinding wheels or disc attachments cannot. Machinists, fabricators, and maintenance technicians typically reach for this size when finishing internal diameters, weld seams, or cast edges on ferrous and non-ferrous workpieces. The cloth backing provides flexibility to conform to curved surfaces without aggressive gouging.

Key Features

Compatibility

Designed as an OEM-style replacement or standard-use mounted flap wheel for die grinders, rotary tools, and flex-shaft machines accepting a 1/8 inch shank accessory.

Installation Notes

Installation is performed by trade machinists, fabricators, or maintenance technicians using standard rotary or die grinder equipment. Before mounting, confirm the tool spindle accepts a 1/8 inch shank and verify the tool's rated free speed does not exceed the 40,000 RPM maximum of this wheel. Always allow the wheel to run up to speed before contacting the workpiece, and wear appropriate eye and face protection. Inspect the wheel for damage before each use and discard any wheel showing signs of delamination or cracking.
