For the drills with the oil feed holes parallel to the shank, which run from one end of the drill to the other, is a different bushing made for every diameter of drill? Also, is the oil fed under pressure? I was contemplating settting up something to use oil-fed drills in the tailstock of my lathe. I'm finding a lot of stuff about the drill bits themselves, but not much on the equipment needed to run them. TIA.
