depending on how many holes your tapping at a time
would it be worth using spiral point taps ?

some years ago while repairing some PCB's out of a EMI-MEC sprint automatic capstan lathe ( not my day job
)
I noticed the lathes didn't periodically reverse the taps to clear the chips
only reversing to remove the tap at the end
if I remember correctly the taps looked like the E887 taps on page 38
in fact the spindle never stopped during the day, just changed speed and direction as required
(every second counts when your making tens of thousands of parts)
I can see if your tapping a lot of holes
the combination of your tapping machine and taps that can be driven all the way in one go will save a lot of valuable time
