Cutting hole in Eternit slate roof for Flue pipe

I want to pass a 150mm double-wall flue pipe through an Eternit slate roof. I have the lead flashing, Storm collar and support braces, but would be grateful if anyone could advise the best way to make a clean hole in the roof / remove tiles, and what tools are recommended?

I have Marley Eternit slates, each with 2 copper nails at the top and 1 copper rivet centre/bottom.

Many thanks for your help.
