My first chucks were Jacobs Bearing Super chucks. Decent chucks, except what I found was that the jaws wouldn't evenly grip the bits and would on occasion spin the bit. The uneven gripping was was worse when trying to grip the smaller bits. So by tightening at each of the 3 points they gripped better. But doing that when on the lathe tail stock is a pain. I then bought the Albrecht. Oh my God! What a difference! No gaps between the jaws and bits, easy to tighten and untighten, therefore very quick to change bits. And the gripping force is unbelievable. They will tighten on the bit as they experience higher drilling torque. I had to drill a couple holes in 1/2" steel plate with a 3" hole saw on the mill. They gripped so tightly I had to use a strap wrench to loosen the chuck to remove the hole saw. If you can, get an integrated shank. Shorter overall length, less possibility for inaccuracies and fitment issues. The small Albrecht that I have only goes up to 3/8", and I would like to eventually get the 1/2" with integrated MT4 shank. The only thing you have to be careful of is that because of its self tightening feature power tapping can be an issue. Though, I've not had problems that way. (But I've never power tapped with smaller than #10)
