Favorite insert cutter in Ti 6-4

[THEE THAINZ™]

Just wondering the opinions of who makes the best inserts and holders. Walter, Iscar, Sandvik, or ???

Thanks for any input.

I just finished another project using Sandvik's 390 series cutter machining Ti. I used 32mm and 54mm both mounted in Big Plus C5 Capto holders.

Mill turning a fairly large part I am easily getting 1+hr of cut time per edge. Cuts like butter.

Once we'll optimize the program through Third Wave we will increase that time somewhere between 20-30% and still be comfortable to run it lights out.
