Merit Abrasives 08834137001 Flap Wheel Adapter

Product Description

The MERIT ABRASIVES 08834137001 is a flap wheel adapter designed to mount flap wheel abrasives onto rotary power tools. It features a 1/4 inch shank diameter and a 5/8 inch shank length, with a 1/4-20 threaded end that accepts compatible flap wheels. Rated to a maximum of 20,000 RPM, this adapter is built for use in grinding, blending, and finishing operations on metal, wood, and composite surfaces. It is sized for use with standard die grinders and handheld rotary tools used across fabrication, metalworking, and finishing trades.

This flap wheel adapter is suited for production and maintenance environments where flap wheels need to be driven by a 1/4 inch collet tool. Typical applications include weld blending, surface preparation, and edge deburring on metal components. The 1/4-20 thread makes it compatible with flap wheels that use the standard threaded arbor mounting system. It is commonly used by metal fabricators, maintenance technicians, and industrial finishing crews working with handheld die grinders.
