Re: mini gun drills

I worked for some time with a shop that does a lot of precision deep hole
drilling. I have used as small as .062 with great results. We did, on
occasion run some as small as .125 in a lathe with a home made stuffing box
and coolant pump.

I was talking to a rocket scientist from Germany yesterday and he was
telling me about tiny gun drills (.035 dia.) they use on manual machines.
They are several advantages according to him: No spot necessary, and a
polished hole that doesn't walk. They sound pretty good for live tool
applications on turning centers. Does anybody have any experience with
them?
