So I'm finishing up my 9x20 Harbor Freight CNC Conversion and I'm going with a VFD and new motor to allow it to do constant surface speed via mach. I have tons of questions but the most important is which inserts are best for finishing and roughing? I know that's a loaded question but I thought that for finishing you wanted a more radiused cutter but it seems like that most are very fine pointed. If it helps I'd like to use one of the tools I already have for either finishing or roughing, whatever it'll do best.

I have this set, the inserts are crap but are standard TCMT 32.52 or TCMT 32.51, but I can replace these with better TiN coated ones. I belive the .51 are 1/64" radius and the .52 are 1/32" radius.

other than that what not too expensive tool and insert should I be using? Thanks.
