Completely agree agreesive flood coolant is best by far and my next SUPER HD MILL (For diy anyway) will have full "drown if you stand still" coolant and enough air to blow the knickers off a Nun at 50yards.:whistling:

The next best thing I've found for ALi is air but lots of it, don't need high pressure just plenty of volume. . . .This and playing with the chipload/RPM and I tend to find the happy medium.

Best alloy cut so far small amount 7075-T6 for some motor bike engine covers very expensive stuff and scrounged from a mate. . Wish I could get some more.!!

Worst stuff some really crappy 5 series that was like cutting string cheese. . . Night mare.

Anyway I'm off to watch F1 Grandprix on Iplayer been away MotoX-ing all day so missed it. . . . . Don't even think of telling me who won because I'm not returning after posting this. .:rofl:
