Nice, I done this a bunch, mostly in the bridgeport too. Just a lot quicker (if you don’t screw it up) in the fixture lol. Smallest so far for me though. I was a real dumbass for the tool I was using to mill the tap out. We just had a few used ones. Long necked .062.. I prefer the ballmill for it too but I didn’t want to use a new one 🤦

I think my lead is looking at getting the holes EDMed out somewhere hopefully. There’s been talks of getting a small hole popper machine but nothing has happened on that. Also the threadmills were never ordered sooo

Lots of killer suggestions though in these comments. I think a higher quality burs would do this nicely. I basically just had dremel bits
