Merit Abrasives 08834137132 Mounted Flap Wheel 120 Grit

Product Description

The MERIT ABRASIVES 08834137132 is a mounted flap wheel designed for precision surface finishing and blending on metal and other hard materials. Built with ceramic alumina abrasive on a cloth backing, this wheel delivers consistent cut and long service life under demanding conditions. The 1/4-inch shank mounts directly into a die grinder or rotary tool, making it a standard choice for machinists, fabricators, and maintenance technicians who need controlled, repeatable results in tight areas. At 120 grit, it falls in the fine grade range, suited for light stock removal, deburring, and surface preparation before coating or inspection.

This mounted flap wheel is used in metalworking, fabrication, and maintenance applications where a standard bench grinder or angle grinder cannot reach. It is well suited for internal bore finishing, weld blending in confined spaces, and cleaning up edges on machined components. The 1/2-inch face width and 1-1/2-inch diameter make it effective in slots, bores, and curved surfaces. It is typically used by machinists, tool and die makers, pipefitters, and maintenance technicians working on steel, stainless, and similar hard substrates.

Key Features

• Ceramic alumina abrasive for aggressive cut and extended wheel life
• 120 grit fine grade for deburring, blending, and pre-coating surface prep
• 1/4-inch shank fits standard die grinders and rotary tool collets
• Cloth backing provides flexibility and conforms to curved or irregular surfaces
• Rated to 25,000 RPM maximum for high-speed tool compatibility
• No interleaf construction for direct abrasive contact and efficient material removal

Compatibility

Designed for use with die grinders and rotary tools fitted with a 1/4-inch collet or chuck. Suitable for finishing steel, stainless steel, and similar hard materials in fabrication and maintenance environments.

Installation Notes

Mounting is performed by a machinist or qualified technician using a die grinder or rotary tool with a compatible 1/4-inch collet. Always confirm the tool's rated RPM meets or exceeds the wheel's 25,000 RPM maximum before use, and never exceed that limit. Inspect the wheel for damage before each use and do not use if the abrasive flaps show signs of tearing or separation. Wear appropriate eye protection and follow applicable workplace safety standards during operation.
