I have a job coming up that is going to require drilling a .125" hole 3" dp in .75" OD 316L stainless on a CNC lathe with y-axis and live tooling. I plan on using a Nachi carbide 25D drill with thru coolant along with the recommended pilot drill in er collet holders. From what I've researched it seems like the best way to go is to run the pilot drill with a static tool and the deep drill with both spindles turning (main spindle 1/3 of the rpm's and live spindle 2/3). Does this sound like the best approach or do I have no business running this on a non specialized drilling machine? Also should I spot drill before the pilot? Btw I planned on using the polygonal turning function to get both spindles counter rotating.
