This little drill chuck satisfies that need and easily holds a #40 drill bit while attached to the large main chuck on the drill press with a hex 1/4" shank. Works perfectly!
I use this little guy on the end of a DeWalt Impact Driver. It has eliminated the need to carry a drill. It's made well, and small enough so it doesn't take up much space. It's small so check your size if you are using for larger drill bits.
Purchased to be able to use cordless driver as a drill instead of having to purchase yet another cordless drill. Works as expected
Adaptor allowed me to keep my old drill bit sets and other attachments from my old drill. A well-built adaptor, and definitely less expensive than having to buy new bits.
