Im sure you're an excellent machinist, but i'd like to see you machine that helmet out of 120kgs of billet ally
Probably take somebody a year lol
The whole point of coolant, i thought, was to prolong the life of the cutting tool by keeping it under a certain temp.

Never said i was when i mean better i was comparing to my work with coolant not the amazing helmet. I wouldn't manage to do that for the life of me lol. I was told that it reduced wear by lubricating the working edge. But I was never paying for the tip inserts and Was regrinding my own HSS tools so if i damaged the tool then it was up to me to fix it.
