Re: Swiss Machining Nckel
really, any carbide is going to be better than hss. a high temp coating like altin our even TiN will help. going slow and chewing tools up us just what nickel does. most manufacturers have drills with geometry specifically for nickel and other hrsa's so that might be a good start. my guess is that with the right drill you could hit size and not bore it unless it's a tight tolerance. nickel sucks and carbide tools are well worth the headache and downtime in the long run.
