Customer Reviews (4.4 / 5 · 5 reviews)

Victoria Y. ★★★★★

The T.I.R. being under 0.0002" was the selling point for me, and it runs true enough that my test indicator barely moved. Hardened and precision ground, it seats my ER-20 collets snugly with no wobble on the JT2 taper.

Leo S. ★★★★★

Swapped out my old holder and this one runs noticeably truer—the 0.0002" TIR spec is real, my test indicator barely moved. The hardened and ground finish feels solid in the spindle, and all my ER-20 collets seat without any fuss.

Emily ★★★★☆

I needed a JT2 to ER-20 adapter for a light milling job and this one cleaned up the runout nicely, though the finish on the taper wasn't quite mirror-smooth when I first opened it. It seats collets securely and the 0.0002" T.I.R. is definitely tight enough for what I do.
