Hand Drill for 3/8" Drill Chuck
thingiverse
I designed this Handle for a drill chuck from a cheap Habor Freight drill. If you want to make one, but don't want to buy a drill just for this, I've seen them at Lowe's for about $7. You will need a bolt for mounting the chuck to the handle. It is a 3" long 3/8"-24(TPI) hex bolt. The thread on the bolt is a standard for smaller drill chucks so it should work with any drill chuck. I made this to hold drill bits and counter sink bits, so that I can reem and clean any holes my 3d prints. Whenever I export .stl files from Inventor it changes the scale. So I just scale my prints up by 25.4 in the slicer.
