Hey all.
Wondering if anyone might have some experience with Gun Drills on a Manual Lathe. Speeds, feeds, and set-up? They keep blowing up inside the parts I am working. I'm thinking that coolant pressure is most of the problem. The drill is set up true and I'm useing a pilot hole. The material I'm cutting is D2 and H13. I've done some research and it looks like what they call a Ventec Drill will provide better chip flow. Recomended speeds and feeds seem to be extremely high, reason being? Or are these speeds and feeds unobtanable with my low pressure coolant? 5 to 10 psi.
Thanks in advance.
