Jason ★★★★★

This key's square drive was a perfect replacement for my worn-out original—no slop at all when I engage the chuck.

Charlotte Y. ★★★★★

The 12.5 mm square head fits my lathe chuck snugly, no wobble when I turn it. Got it as a spare and it does the job exactly as described.

Timothy G. ★★★★★

Bought this to replace a lost key on my lathe, and the 12.5 mm square head matched the 1/2 inch slot perfectly without any play. It feels solidly machined and grips well when tightening the chuck.
