I work as an R&d machinist and this is the hardest set of parts I’ve had to make to date. Scariest feature was a .9mm hole 25mm deep. The gas ports also line up with a .9mm hole as well. Thread ring is m19x1. Material is 316 stainless. I did such a good job I now need to make two more.
how many pecks for that .9mm feature? gat dam.
rouuughh, seems like a fun part to make tho! I'm not too familiar with wire edm but maybe that could be used to do those .9mm holes more easily, not sure how setup would be done tho but it seems like it might be an option to alleviate how silly that drilling op must be. really comes down to if you even have access to an edm in the first place, but if you are tasked with making more than the extra two hopefully it can improve your life!
I needa fuck around with tinnier drills and cutters but I don't have through coolant or anything fancy on my old ass ycm-40 so I gotta be careful sadly :(. I take it the 3-4mm depth in pecks is to ensure the bits running straight in the material? What kind of runout are you typically working with on those small of diameters?

I haven't had the chance to try those out, currently using a bunch of yg1 dream drills for my steel machining which have kinda ruined my brain with how quick they can plunge and dispose of heat into the chips. For the price I find them very hard to beat but the most demanding drilling I do is usually in annealed 4140.
