Thanks PixMan and DaveH,
Still a little confused on which order I should use the taps, but the way I am doing it seems to be working.
Forgot to mention that I am tapping 3/8 inch steel and already blunted a carbon steel tap after only 2 holes out of 70.
HSS taps seem to be working a lot better and I think I will continue to use all 3 taps for this job, then revert to single tap for easier jobs.
Not convinced that any of the 3 taps are bottoming taps (which was what I was expecting) since all have differing tapers. But no issue, as I am not tapping any blind holes.
Appreciate the hints... Many thanks
