Hope i'm not teaching you to suck eggs, but using carbide tooling on a small lathe is very difficult - they like big hard heavy cuts and generally when cutting below about 10thou they tend to rub rather than cut. Small lathes tend to lack the rigidity to take the loads so you better off with HSS. The one exception to this is I tooled out my little CNC lathe with some tipped tooling but got inserts with 0.1 and 0.2mm nose radius. These are fantastic and are razor sharp to touch - I can take half thou cuts with them. So if you do want Carbide tooling I suggest you go for the smallest nose radius possible.

Cheers

Dave
