Ella B. ★★★★★

Machined the slots perfectly on my old import chuck, these inside jaws fit without any filing or fettling. The teeth match the originals exactly, so the gripping action is just as solid as day one.

James ★★★★★

The hardened steel teeth gripped the workpiece firmly right out of the box, and the mounting holes matched my lathe's chuck exactly without any filing. They fit tight and haven't slipped once in a week of turning steel.

Lucy K. ★★★★★

The serrations lined up perfectly with my existing chuck, so swapping the old worn jaws took under five minutes. These replacements feel solid and hold a 1/2" rod dead center with no wobble.
