I am pleased with the chuck and I rate it 5 stars. It is on the large size but after I put it on the drill press the size was okay. It is easy to put on. I turned the jaws inside the chuck so they weren't showing and placed the chuck on shaft with the table adjusted to touch the bottom of the chuck and using the turn bar I pressed the chuck up tight on the shaft.Be sure the jaws are not sticking out of the chuck when you press the chuck on, that's how I damaged the original chuck.Amazon is the only place I found a 33Jacob chuck. thank you Amazon.
