Can anybody supply a hardened 440 stainless steel ball that is drilled, and tapped, then polished or lapped to a smooth surface?
Or would it have to be annealed first, then drilled, tapped, hardened, and then polished or lapped to a smooth surface?
Are both ways possible, which would be the best way to do it?
Is one method a lot more expensive?
Please advise any and all expert opinions on this matter.
If you can supply a 5/16" round, hardened 440 stainless steel precision ball that is drilled and tapped, please leave me your contact information and or proposal.
