Value Collection QC-1420 Flap Wheel Adapter 1/4-20 Thread

Product Description

The VALUE COLLECTION QC-1420 is a flap wheel adapter designed to mount abrasive flap wheels onto rotary tools and die grinders. It features a 1/4-20 threaded stud for secure flap wheel attachment, a 1/4 inch shank diameter for compatibility with standard collets and chucks, and an overall length of 1-3/4 inches. The 1/2 inch shank length seats firmly in the tool chuck, minimizing runout during operation. This adapter is a workholding accessory used by machinists, metal fabricators, and maintenance technicians to quickly change between flap wheel sizes without swapping tools.

The QC-1420 flap wheel adapter suits bench grinders, angle grinders, and handheld die grinders used in metal finishing, deburring, and surface preparation applications. It is well suited to light industrial and maintenance environments where threaded flap wheels in the 1/4-20 thread standard are routinely used. The compact 1-3/4 inch overall length keeps the flap wheel positioned close to the spindle for better control during finishing passes on metal, weld joints, and contoured surfaces.

Installation Notes

Installation is performed by machinists or maintenance technicians using standard hand tools. Power down and unplug or lock out the rotary tool or grinder before inserting or removing the adapter shank from the collet or chuck. Tighten the collet nut to the tool manufacturer specification before mounting the flap wheel onto the 1/4-20 threaded stud. Inspect the adapter for wear or damage before each use and replace if threads show stripping or the shank shows runout.
