Merit Abrasives 08834137474 Mounted Flap Wheel 240 Grit

Product Description

The MERIT ABRASIVES 08834137474 is a mounted flap wheel designed for precision grinding, blending, and finishing in tight or contoured areas. It features a 3/8-inch outside diameter and a 3/8-inch face width, making it well suited for small-bore work and detailed surface preparation. The abrasive material is aluminum oxide coated cloth at 240 grit, placing it in the very fine grade range for light stock removal and smooth finishing passes. A 1/8-inch shank mounts directly into a die grinder or rotary tool. Maximum rated speed is 40,000 RPM. This wheel is commonly installed and used by machinists, tool-and-die workers, metal fabricators, and maintenance technicians.

This mounted flap wheel is used in applications requiring controlled finishing on metal surfaces, weld blending in restricted access areas, deburring of drilled or machined holes, and surface conditioning on ferrous and non-ferrous substrates. The small diameter and cloth-backed flap construction conform to curved or irregular profiles where flat abrasives cannot reach. It is appropriate for both bench-top rotary tool use and inline die grinder work in production and repair environments.

Compatibility

Designed as an OEM-style replacement mounted flap wheel for use with standard 1/8-inch collet die grinders and rotary tools rated to at least 40,000 RPM.

Installation Notes

A licensed machinist or qualified technician should install and operate this wheel. Before mounting, verify that the rotary tool or die grinder collet is rated for a 1/8-inch shank and that the tool's maximum RPM meets or exceeds 40,000. Always inspect the flap wheel for damage before use and ensure the shank is fully seated and the collet nut is securely tightened. Wear appropriate eye protection and follow all applicable shop safety procedures when operating abrasive wheels.
