Indicator Holder, 3/8" Square Shank

I've been using this to center work in my 4-jaw chuck, and the 3/8" square shank locks in my tool holder without any wobble. It makes dialing in parts way faster than my old method of fiddling with a test indicator on a magnetic base. Definitely a solid upgrade for the lathe setup.

This holder’s square shank fit perfectly into my tool post right out of the box, making setup effortless. It centers work in a 4-jaw chuck exactly as described, and the solid feel gives me confidence on the lathe.

Took a while to find a holder that actually fits my quick change tool post without any fiddling, and this one seats the indicator dead center over a 4-jaw chuck every time. The 3/8" square shank locks down solid, so the needle stays put even when I'm nudging the jaws.
