Hi again , now that ive started fiddling around with my new Sieg 550w Lathe , i am truly bewildered by the amount of different types of inserts available . i have looked on the net and am not much wiser ! regards what to select. I believe CNMG ? are the most popular or is it CCMT for small machines , i will be only attempting very basic Lathe work at first , mainly in Aluminium to start with , i already have a QCTP and some boring bars , Live Center and Drill Chuck , just need advice on a few standard issue Holders for facing andside cutting/sleeving , cheers.
