Richard C. ★★★★★ Oct 19, 2026

I was worried about compatibility with my mini lathe, but the 20 TPI threads match perfectly and the 0.050" per revolution makes zeroing in simple. The dial's 33 mm outer diameter feels sturdy and precise under my fingers.

Edward ★★★★★ Oct 18, 2026

The 50 divisions make dialing in cuts on my cross slide painfully simple—each line is exactly one thousandth, which is perfect for this 20 TPI setup. Fits snugly at 33 mm and the markings are crisp enough to read even under shop lighting.

Swapped this onto my compound rest and the fit was dead on at 12mm ID, no wobble at all. The 33mm face is easy to read and the 20 TPI markings line up perfectly with my leadscrew, so dialing in 0.050" per turn finally makes sense.
