Dick,
If you set up the Uni as a mill/drill press and use a spiral point tap
you could knock these out pretty quickly, if you have a reversing motor.
With the standard Uni motors removing the tap will take a bit of hand
cranking. How much cranking depends on the depth of the hole.
For through holes a spiral point tap is what you want. For blind holes
use a spiral flute tap.

Charles,
I owned two Tapmatic tappers some years ago. They are nice to use and I
wish I still had them. They are very expensive to buy even on the used
market. It is not cost effective for me and the job I have.
