I purchased this to change the drill head of WEN 4212T drill press. Some of the reviews said this was too big for JT33, some said it worked for them. The wedge opens about 0.72 and the exposed portion of the JT33 is about 0.62. For it to pull anything out from the quill, it needs to: 1. Open wider than the exposed JT33 (0.62 in this case), 2. Can't open wider than the drill head or the quill (more than 1 in this case), 3. Thin enough to fit in between the drill head and the quill and thick enough to separate them when wedged. It satisfied all 3 conditions but I wasn't sure if it will separate the drill head from the arbor or the arbor from the quill. It did separate the drill head from the arbor, which was what I wanted. If it pull the drill head and the arbor out together, then I think it won't work for separating the drill head from the JT33 2MT (0.7 dia) arbor. Maybe that is why the reviews are not consistent?
