Review on Grizzly Industrial G8784 4-Jaw Chuck With 1 Inch Round Piece Capacity And 8 TPI Thread. by Brad Arthur

Wll This is pretty much what I expected. This chuck works but I imagine the more expensive chucks work much better and can achieve a better grip on the work piece. I do not know what problems the other reviewer was experiencing but I have only used this chuck to grip the OD of the work (I imagine ID would work as well). The 1st 1/8" or so is tapered inward and I have found making a short tapered tenon to work the best in OD gripping situations although since I am a beginner and do run into the occasional big catch I have been able to knock the work out of round. My biggest complaint would have to be the included "wrenches" which are nothing more than a couple pieces of round stock. These tend to bend when trying to get a real good grip on the work. Other than that though I feel I got my $40 worth but will probably get a better chuck in the future and will probably try coming up with some stronger "wrenches".
