Drill Chucks

Most mini mills come with a drill chuck. (At LittleMachineShop.com we find that most factory installed drill chucks are of very low quality. It is for this reason that we have the factory install upgraded drill chucks in all of our HiTorque mini mills.)

There are two types of drill chucks to choose from, keyed chucks and keyless chucks. Keyless chucks offer convenience and safety. Keyed chucks are more economical, and they provide slightly (and only slightly) more holding power. We have keyless chucks on our mini mill and drill press and use them for everything.

A drill chuck alone has no way to mount in the mini mill. A drill chuck arbor  has one end that fits in the back of the drill chuck and another end that goes in the mini mill's spindle. The chuck to arbor connection is pretty much permanent. You can remove an arbor from a drill chuck, but it takes a pair of special U-shaped wedges to do it.
