Kevin E. ★★★★★

Mounted this arbor on my mill and the R8 taper fits snug without any wobble. The 33JT end seated perfectly on my chuck, saving me from having to buy a whole new setup.

Violet R. ★★★★★

This arbor fit perfectly into my mill's R8 spindle with no runout, and the 33JT taper locked onto my chuck firmly on the first try. Saves me the hassle of swapping chucks between machines.

William ★★★★★

The 33JT taper seated snugly against my chuck with zero wobble, and the R8 end locked into the spindle just as cleanly. Swapping tooling took me under five minutes, which is way faster than my old setup. Exactly what I needed for this conversion.
