Mcmaster has a variety, here are two:
p/n 8505A41 has a .125" tip, .1875" shank, and .03125" radius
p/n 8508A45 has a tip of .090" and, .25" shank, and a .075" radius.
That would work if the holes were on a flat surface, but they are on a radius so the cutter would really have to hog in deep to get all the way around.
Just looking at an uprated PC....it might get you 90% there, and then blend in the lower portions by hand, or it might just do it on its own. You will want a carbide one, or at least cobalt, cutting fluid and slow speed. Some times you just have to try something to know for sure.
Personally, I have not tried to taper or radius the inlet yet, so I will add that to the next set I do.
For reference, I am currently running .136 dia burn holes in my 616 turbo and will be going to .145 with a tapered inlet when I put in the Bosio nozzles.
larsalan I guess I need to look at this stupid ass drip shit. What you have to like mess with those elements on the pump? What a fucking hassle. then use some wire to hold the throttle open or some shit?
