Brian ★★★★★

I needed to extend the reach on my flap wheel and the set screws hold the shank firmly in place with zero wobble during use. The 8-inch version gave me plenty of clearance in tight spots, and it's solidly built for the price.

Kevin W. ★★★★★

The 6-inch length gave me just the reach I needed for a tight spot, and the set screws locked my flap wheel on tight without any wobble. Much better than rigging something with tape.

Claire ★★★★★

Exactly what I needed to extend my flap wheel’s reach—the set screws keep it locked tight even under heavy use. The 6-inch shank gives me just the right clearance for deeper work.
