Trying to convert these flanges, from screw in studs, to press in ARP studs.
I only need to increase the size a couple hundredths and my new drill bits don’t seem to be cutting, because it’s using so much of the outside edge?
Would it be better to use a reamer?
The knurled section is .510; the threaded section is .468; what size drill bit or reamer would you recommend? My drill bit was .498
