Merit Abrasives 08834137543 Mounted Flap Wheel 180 Grit

Product Description

The MERIT ABRASIVES 08834137543 is a mounted flap wheel designed for precision grinding, blending, and finishing on contoured or hard-to-reach surfaces. It measures 0.625 inches in outside diameter with a 0.75-inch face width and mounts via a 0.125-inch shank for use in die grinders, rotary tools, and drill presses. The abrasive material is aluminum oxide on a cloth backing, rated at 180 grit for a very fine finish grade. A maximum operating speed of 37,000 RPM makes it well suited for high-speed rotary applications where controlled material removal and surface refinement are required. Machinists, tool-and-die workers, and fabricators rely on this type of wheel for finishing bores, ports, and recessed areas.

This mounted flap wheel is used in metalworking and fabrication environments where a small-diameter abrasive tool is needed to access tight geometries. Typical applications include deburring internal bores, blending weld seams in confined spaces, and finishing hardened or cast surfaces. Its very fine 180-grit designation makes it appropriate for final-pass finishing rather than aggressive stock removal. The cloth backing provides flexibility and conformability against irregular surfaces.

Key Features

• 180 grit aluminum oxide abrasive for very fine surface finishing
• 0.625-inch outside diameter for access to tight or recessed areas
• 0.75-inch face width provides adequate contact area during finishing passes
• 0.125-inch shank mounts directly in standard die grinder or rotary tool collets
• Cloth backing allows the wheel to conform to irregular or contoured surfaces
• Rated to 37,000 RPM for compatibility with high-speed rotary tools

Compatibility

Designed for use with die grinders, rotary tools, and drill presses fitted with a 0.125-inch collet or chuck. Suitable as an OEM-style replacement or direct-fit abrasive wheel for standard shank-mounted flap wheel applications.

Installation Notes

Installation and operation should be performed by machinists, tool-and-die professionals, or qualified fabricators familiar with abrasive tooling. Before mounting, verify that the tool spindle speed does not exceed the 37,000 RPM maximum rating marked on the wheel. Inspect the wheel for damage before each use and ensure the shank is fully seated and secured in the collet. Always wear appropriate eye and face protection when operating rotary abrasive tools.
