Merit Abrasives 08834137492 Mounted Flap Wheel 120 Grit

Product Description

The MERIT ABRASIVES 08834137492 is a mounted flap wheel designed for precision deburring, blending, and finishing work on metal and other hard surfaces. Built around a 1/8-inch shank mount, this wheel carries aluminum oxide coated cloth flaps arranged radially around a central hub. The 1-3/16-inch outer diameter and 1/8-inch face width make it well suited for work in tight bores, ports, and contoured areas where larger wheels cannot reach. At a fine 120-grit rating, it removes light surface imperfections and leaves a smooth finish. It is rated to a maximum of 30,000 RPM, making it compatible with die grinders and rotary tools commonly used by machinists, pipefitters, and fabricators.

This mounted flap wheel is used in metal fabrication, pipe and fitting preparation, weld blending, and surface conditioning applications. Its small diameter and shank-mount design allow it to reach inside tube ends, valve bodies, fittings, and other confined geometries. Fine 120-grit aluminum oxide coated cloth is appropriate for final-stage finishing passes where material removal needs to be controlled. Trades that commonly use this type of wheel include pipefitters, plumbers preparing copper or steel fittings, HVAC sheet metal workers, and general fabricators working on ferrous and non-ferrous metals.

Key Features

• 120-grit aluminum oxide coated cloth flaps for fine-grade surface finishing
• 1-3/16-inch outer diameter fits tight bores and contoured work areas
• 1/8-inch shank mount for use with standard die grinders and rotary tools
• 1/8-inch face width for controlled, precise contact with the work surface
• Rated to 30,000 RPM maximum for compatibility with high-speed rotary tools
• Cloth backing provides flexibility and consistent flap contact during use

Compatibility

Designed for use with rotary tools and die grinders accepting a 1/8-inch shank, consistent with standard collet sizes found on most pneumatic and electric die grinders used in trade and fabrication settings.

Installation Notes

This wheel is installed and removed by a licensed or qualified machinist, fabricator, or trade professional using the appropriate collet wrench for the host tool. Always confirm the host tool RPM rating meets or exceeds the 30,000 RPM maximum rating of the wheel before use. Ensure the wheel is fully seated and the collet is properly tightened before operation. Wear appropriate eye and face protection as required by OSHA standards when operating abrasive wheels.
