Awl --
No foolin. My machinist friend has a job drilling boucou 5/32 holes in 1/8 304 stainless, w/ carbide drills, and he says he wouldn't even take the job if it weren't for Crisco vegetable shortening. It's solid-ish at room temp, but of course quickly melts.
He *swears* that there is not only a diff between the crisco and black cutting oil, but that the diff. is profound. He has boucou experience in the trade, as well.
Inyone else do this, hear of this? Would lard work, as well?
Any other more "dignified" cutting solutions, ito soluble oils, etc?
