Hi:
G84.1=Flexible tap cycle(floating holder) specifying thread Pitch (1/tpi)
G84.2= Flexible tap cycle (floating holder) specifying thread TPI (threads/inch)
I can see no benefit or preference, other than we'd be less likely to make a calculation error if we input the TPI. With a floating tap holder, (please verify with the manufacturers suggestions) you just need to touch off like any other tool. The floating tap holders allow for some tension and compression. As far as the coolant concentration is concerned, that is dependant on the coolant properties, and of course the material you are tapping.
