Im boring out a 0.75" round bar of 303 stainless steel first with 0.5" drill 3.4" deep then with a 14mm drill 3.0" deep on a lathe. Is there a special formula for adjusting the speed and feed of the 14mm to break the chips? I'm running it with live tooling at S416 F0.011 and can not get the chips to break. Any help would be appreciated!
