Need help with tooling, specifically drill

You don't need a ton of coolant pressure, just need to keep the part cool while drilling. Heat will build up quick.
Depending on how deep you need to go you might have to retract all way to make sure coolant gets in there if you can't put it thru the drill itself.

What speed and feed would you suggest? The website for the drill suggest a feed of .01-.012 with 3500 rpm. I was thinking maybe 1000-1500 rpm, what would you suggest? Also does that feed sound high enough? I need to drill 12xD

This is what my program looks like as of right now. The site suggests to do a pilot hole with pilot drill 100% S and F. Then to feed 12xD drill max 50 rpm, then 75% S&F 1xd past pilot hole and then 100% the rest of the way. I have made it where I am basically doing that but giving it a break halfway through. That way I can also check on the drill at that point. We bought this drill so it would be quicker because the pecking takes so long.

That's not terrible, I wouldn't go 3500 rpm for sure, at most 2k rpm with a drill that size on a lathe in nylon. Feed might be slow, might be spot on.

It's mostly a "feel" type of thing that you'd have to run it and adjust on the fly.
If it looks good and produces a nice hole in a quick enough time then send it.

Thank you for your help. I appreciate it alot.
