Henry ★★★★★

Finally, a chuck that doesn't add unnecessary bulk. The integrated R8 shank and 7/16"-20 drawbar thread make swapping between tools smooth and the rigidity is noticeably better than my old adapter setup.

Henry K. ★★★★★

I’ve been using this on my milling machine and the integrated R8 arbor makes swapping tools so much quicker. The tighter grip from the keyless design gives me noticeably less runout than my old setup.

Scarlett ★★★★★

Fits perfectly on my Bridgeport mill and the rigid one-piece design eliminated the runout I had with my old setup. The shorter overall length is great for tight setups where every millimeter counts.
