Actually I wasn't aware there are spiral flute and spiral point taps. I thought there are just straight and spiral taps. I will have to try the spiral point taps. What I love about the "internet community" is - you can have some input for others and you can learn something as well. This is really great.
About the taps I was using here - I was feeling at some point of using one of the spiral flute tap some bigger resistance so as always I just decided to break the swarf. Should I ignore this and try to cut with no swarf breakage? I was a bit worried here honestly. Most of my life I was using usual hand taps or machine straight flute taps.
Thanks for your hints!
