Hi
Gang:
It is
easy to drill and tap a drill chuck to fit Unimats, I've done
it to chucks up to 1/2" capacity. I mostly use the 1/4" chuck
converted in 1973.
While
you can hold a milling cutter in a drill chuck, you will not
come close to cutting capacity of the cutter. Most likely the
cutter will move or even be ejected by cutting forces.
Much
better is to make solid cutter holders from 3/4" bar stock.
Drill and tap to match the spindle then bore for your cutter
and add a set screw to clamp the cutter. I have 3/8" and 1/2"
holders that work fine.

and how accurate you need to be.
Drill chucks to fit M14 x 1 (Unimat 3 / 4) or M12 x 1 (earlier
Unimats) are probably easier to find than collet chucks with
those threadings.
