Merit Abrasives 08834137542 Mounted Flap Wheel 120 Grit

Product Description

The MERIT ABRASIVES 08834137542 is a mounted flap wheel designed for precision grinding, blending, and finishing on contoured and irregular surfaces. The wheel measures 5/8 inch in diameter with a 3/4 inch face width and uses aluminum oxide coated abrasive cloth at 120 grit, which falls in the fine grade range. A 1/8 inch shank mounts directly to a die grinder or rotary tool, making it straightforward to deploy in tight clearances. The wheel is rated to a maximum of 37,000 RPM. Metal fabricators, machinists, and maintenance technicians reach for this tool when a standard wheel or disc cannot reach a recessed weld, bore edge, or port opening.

This mounted flap wheel is suited for light stock removal, surface blending, and edge deburring on metal workpieces. Its fine 120 grit makes it appropriate for finishing passes rather than aggressive material removal. Common applications include cleaning up weld beads in pipe interiors, deburring drilled holes, and smoothing machined surfaces in confined areas where larger abrasives cannot fit. It is used across industrial maintenance, HVAC component fabrication, and general metalworking shops.

Key Features

• 120 grit aluminum oxide coated cloth for fine finishing and surface blending
• 5/8 inch diameter allows access to tight recesses and small bores
• 3/4 inch face width provides stable contact on contoured surfaces
• 1/8 inch shank fits standard die grinders and rotary tools
• Rated to 37,000 maximum RPM for compatibility with high-speed rotary tools
• Cloth backing with no interleaf for consistent abrasive contact throughout wheel life

Compatibility

Designed for use with die grinders and rotary tools accepting a 1/8 inch shank. Suitable for ferrous and non-ferrous metal finishing applications where a small-diameter mounted abrasive is required.

Installation Notes

Installation is performed by inserting the 1/8 inch shank into the collet of a compatible die grinder or rotary tool and tightening per the tool manufacturer specification. Always verify the tool RPM rating meets or exceeds 37,000 RPM before use, and do not exceed the wheel's maximum RPM rating. Wear appropriate eye protection and a face shield during operation. Inspect the wheel for damage or loose abrasive flaps before each use and discard if defects are found.
