If you have machining capabilities, heim balls are 8740-high-carbon steel but can be quickly cut oversize on a mill or lathe with a sharp cutter (NOT a drill!), slow speed, light cuts & plenty of lube. Skimp on any of those and the cut area will work-harden ahead of the cutter from heat and you just made junk. I haven't tried it but a small brake hone might open up a heim ball. I prefer a mill & carbide cutter. Remember to keep the ball cool while enlarging by any means!

Or you can simply purchase the correct metric heim joint and save yourself a lot of hassle!
