You can look at gun drills ( very little to do with guns, but very much
high pressure drilling )
Used in mold shops for deep coolant holes. They cut straight and fast.
If you blow a coolant line on these its dangerous.
the drill doesnt look like those in your toolbox

Deublin units work well. The problem is tool retention design they will not
take direct thrust. They may have other products you can adapt.

Hey everyone just wondering if anyone has ever used a rotary union to
plumb through spindle high pressure coolant into their machine. I am
thinking about doing it and just looking for advice. I have the high
pressure pump already and there is a hole down the middle of my spindle. I
just need a rotary union I think and need to do some machining to make it
all fit..
I have no idea what type of rotary union I need though....
regards
Andrew
