Yes, too light for a milldrill, at least for my taste in speed and
power. A mill drill has an R8 spindle and enough hp in the spindle
(2 hp)to take advantage of it. You don't want to stall out an axis
just because your 3 inch fly cutter got dull. Maybe a bigger motor
and our drivers, but our Globe motors are about equivalent to a 250
oz-in stepper, without the top end speed limitations that driving a
stepper at 30 volts would entail.
