what do you guys run for cutting oil for threading stainless steel
my dad love the castrol mollydee but its 100 dollars a gallon and it stains everything but it does work good
we thread a lot of 3 in 304 ss acme 4 tpi shafts 30in of thread if we run just coolant inserts last maybe two parts so we run cutting oil and the inserts last maybe five parts
any help would be great thanks
