I hadn't thought of using it for tapping. It ought to work, at least
for larger sizes.

The larger the tap, the greater the torque requirement (large at work is
M36). Could be difficult.

If I can keep the tap properly aligned by hand. What
I've been using is a piloted tap wrench in the drill press.

You should try a spiral-point tap, in the drill chuck. Ideally your drill
press reverses to pull the tap out. Probably still faster than hand tapping
if you can only run the tap under power forwards.
