Description
The MERIT ABRASIVES 08834137323 is a mounted flap wheel designed for precision surface finishing and deburring on metal and other hard materials. Built with aluminum oxide coated abrasive on a cloth backing, it delivers consistent stock removal and blending in a very fine 180-grit grade. The 1/4-inch shank mounts directly into a die grinder or rotary tool, making it a practical choice for machinists, fabricators, and tool-and-die tradespeople who need controlled finishing in tight areas. Rated to 30,000 RPM, it handles high-speed rotary applications without compromising abrasive integrity.
This mounted flap wheel suits contour finishing, weld blending, and bore or cavity work where a larger grinding wheel cannot reach. At 1-3/8 inches in diameter with a 5/8-inch face width, it fits comfortably into slots, ports, and curved surfaces. The 180-grit aluminum oxide construction makes it well-suited for final-pass finishing on steel, stainless, aluminum, and cast iron components in both shop and field service environments.

Compatibility
Designed for use with standard 1/4-inch collet die grinders and rotary tools commonly used in metal fabrication, machining, and finishing applications.
Installation Notes
Installation is performed by machinists or fabricators using any die grinder or rotary tool with a 1/4-inch collet. Ensure the tool is powered off and disconnected from the air supply or electrical source before mounting or removing the wheel. Always confirm the tool RPM rating meets or exceeds the 30,000 RPM maximum before operation, and inspect the flap wheel for damage before each use. Use appropriate eye protection and follow shop safety protocols when operating abrasive accessories.
