Tapping Aluminium profile

[JAZZCNC]

Having done a bit of tapping on aluminium recently I found a spiral point tap infinitely better than any of the standard 3 hand-taps. You can pop it in a cordless drill and with a drop of oil down the hole it cuts it like soft cheese.

Told you so.!! Hisn't the difference between standard taps and spiral taps amazing.!!

Do I need to use a taper tap first or can I just use a middle tap on Ali profile? Thanks

Cutweltools at dewsbury is the place to get them from. High quality and not silly money. . . . Tell them it's for aluminium.
