Nicholas U. ★★★★★

Finally, a chuck key that doesn't slip off the square drive. The 9.5 mm fit is snug and precise on my lathe's 3/8" chuck, making adjustments much easier than with my old worn-out key.

Richard ★★★★★

The 9.5 mm square drive fits my 3/8" chucks without any slop, so it turns smoothly instead of wobbling like the old one did. Solid enough for everyday use on the bench lathe without feeling flimsy.

William ★★★★★

Bought this to replace a worn-out key and the 9.5 mm square drive seats solidly in the chuck without any slop. The fit is snug enough that I don't worry about it rounding off the corners, and the length gives good leverage for tightening.
