Customer Reviews (4.4 / 5 · 5 reviews)

William I. ★★★★★

The integrated R8 arbor makes mounting this chuck rock-solid on my mill—no adapter needed. It’s noticeably more compact than my old setup, which gives me better clearance on smaller jobs.

Owen ★★★★★

Ran a few test pieces and the runout is noticeably better than my old separate chuck and arbor setup. The 7/16"-20 drawbar thread engaged smoothly, and the compact length lets me use shorter end mills.

Ryan R. ★★★★★

The integrated R8 shank makes mounting this chuck a breeze, and the 7/16"-20 drawbar thread mates perfectly with my mill. It's noticeably more rigid than my old separate chuck setup, and the compact size is a huge plus for tight spindle clearance.
