Customer Reviews (4.4 / 5 · 5 reviews)

Ella ★★★★★

Finally got to use this on the mill and the 0.25" measuring range is perfect for centering small fixtures quickly. It fits snugly in the collet and the whole setup feels precise.

Jason V. ★★★★★

Finally, a way to get my workpiece perfectly centered without all the guesswork. The 0.25" range is just right for my mill, and the 0.375" shank fits snugly in my collet.

Victoria ★★★★☆

The shank on this thing is solid—that 0.375" diameter fits my collet without any wobble, and the 5.5" overall length gives good reach. Took a bit of fiddling to get the dial zeroed, but once it’s set, centering work pieces is quick and repeatable.
