you will have to write your own drill cycle in order for the coolant to come on at every time it retracts to the R plane that you are using in the G83
there is no way for the control to generate the coolant on / coolant off at each full retract
Hi,
I have a job where i’m drilling deep holes and i would like to have the coolant start briefly when i have retracted the drill bit.
Is there a way to do this without writing my own drill function?
I’m using G73 for making these holes.
Full retract for every 8mm total lenght 400mm

Why not just run the coolant through the full drill cycle? That's the way I do it.

Oops... after writing this I just noticed I'm in a Turning section. Hope this still applies. At least partially. Was thinking mill. Sorry. (Head slap!)
I've got a feeling the OP does not have an enclosed machine and is hoping to avoid a big mess.
Just for fun... here is 1/4 of what might work. You would need to continue in kind down to Z-400. I tried to figure out how to write it with a small subroutine called multiple times with a built in on-the-fly offset change. Couldn't quite figure it out and didn't want to spend all day trying so I left it at this.
Macro pros could probably come up with something much better then this.
This is generic Fanuc based. May or may not need to repeat the position call X0.Y0.
I'm about 90% certain this would work. Just not sure how the control will react with all the M and G4 stuff stuck in between drill attempts.

The other option. Needs a quick trigger finger on a squirt bottle full of coolant. :-)
