Customer Reviews (4.4 / 5 · 5 reviews)

Daniel X. ★★★★★

I was pleasantly surprised how snugly the 4-jaw self-centering mechanism grips my octagonal stock, and the radial runout is impressively low for the price.

Daniel Y. ★★★★★

The 16mm through bore is exactly what I wanted for passing longer stock through the back, and the 4-jaw self-centering action grabs square stock dead true. Body feels solid for a 3-inch chuck, no slop in the gears when I tighten it. Mounted it in about ten minutes and it’s already earned its spot on

David B. ★★★★★

The 16mm through bore is perfect for my small precision work, and the 4-jaw self-centering action gripped my octagonal stock tightly on the first try. Runout was minimal right out of the box, which saved me a lot of setup time.
