Tru-maxx SZFWA1 Flap Wheel Adapter 1/4-20 Thread

Product Description

The TRU-MAXX SZFWA1 is a flap wheel adapter designed to mount flap wheels onto standard rotary tools, die grinders, and drill chucks. It features a 1/4-20 threaded end for secure flap wheel attachment and a 1/4 inch shank diameter for compatibility with common collet-style tool holders. Overall length measures 2 inches, with a shank length of 5/8 inches. The adapter is a compact, single-piece component used by machinists, fabricators, and maintenance technicians to extend flap wheel tooling capability on existing power tools.

This adapter is suited for metalworking, woodworking, and general surface finishing applications where flap wheels are used for deburring, blending, or light material removal. It is typically installed in shop environments using hand-held rotary tools or bench-mounted drill presses. The compact form factor makes it practical for tight-clearance work where larger grinding accessories are not practical.

Installation Notes

Installation is performed by machinists or tool operators familiar with rotary abrasive tooling. Ensure the rotary tool or grinder is fully powered off and unplugged before inserting or removing the shank from the collet or chuck. Tighten the collet securely around the 1/4 inch shank before operating to prevent slippage. Always confirm the flap wheel is threaded fully onto the 1/4-20 end and inspect for secure seating before running the tool.
