A quality product with one flaw.

Well machined and does what it is designed to do. On my HF lathe, when using the worm screw, the chuck will not screw on to the spindle all the way, because the jaws close down too far. Others have complained that it is difficult to use the two tightening bars, but once you know the secret of the fire swamp, it really is very easy to tighten the chuck with just one hand. A quality product with just the one flaw, so it loses one star.
