I've turned and threaded ballscrews without any problems? They are only
usually 4140 or 4150 alloy steel or 1050 Carbon steel. You need to take
deep roughing cuts to get through the surface hardness with Carbide
insert tooling. Something like Iscar IC3028 inserts are good for that.
Once through the surface they are no trouble at all with normal insert
tooling.
