As the title says.
I have serious problems getting our small carbide drills to last any significant number of parts at all in stainless because the machine has no through-spindle coolant.
I'm not being crazy, I don't think. I don't try deep holes with them. But. Surely a 4.3mm should be able to clear five millimeters (1/5 in) in 304? Drills look like total trash after only say fifty holes and fiddling with the speeds and feeds hasn't helped either.
Are SC drills without coolant channels noticeably stronger?
Does anyone have any ideas?
