Product Description

The NORTON 63642543319 is a flap wheel adapter designed to mount abrasive flap wheels onto rotary tools and die grinders. With an overall length of 4 inches, a 1/4 inch shank diameter, and a 1/4-20 threaded end, this adapter provides a secure mechanical connection between the tool spindle and the flap wheel. It is a replacement-style accessory used by metalworkers, fabricators, and maintenance technicians who need reliable flap wheel attachment for surface blending, deburring, and finishing operations on metal, wood, or composite materials.

This adapter is suited for use with angle grinders, die grinders, and drill press setups where a 1/4 inch shank is accepted. The 1/4-20 thread accepts standard threaded flap wheels used in light to medium material removal and surface conditioning tasks. Typical applications include weld blending, edge deburring, and surface prep work in fabrication shops, maintenance environments, and field service settings.
