Let’s come back to this, is there a way to adjust one tooth up a thou or so without grinding the insert?
For Steel ISCAR APKT 1604PDR-76 IC928 https://www.ebay.com/itm/10-pcs-ISCAR-APKT-1604PDR-76-IC928/322992042447
For Aluminum Korloy APKT1604PDFR-MA H01 https://www.ebay.com/itm/10pcs-APKT1604PDFR-MA-H01-Carbide-Milling-Inserts-For-Aluminum/162826768705
They are also sold by Glacern under the FM90 link below.
Sometimes one is better off getting something like a Shar's or better yet Glacern cutting head with inserts. At the end of the day, you get much better tolerances and cutting performance for not to much more spend. The other factor that scares me big time is poor hardware and soft screws. One of those goes with an insert, it could cause some serious damage. I also have had better luck buying new old stock or lightly used cutter heads from the same brands mentioned above, I can easily shave a thousandth cleanly off of an aluminum block with a mirror finish. One cutter head that is setup for aluminum has 4 cutting surfaces per insert, so you get a lot of mileage out of them, another has 8 cutting surfaces setup for steel. Also have an APKT 2" head with 6 inserts. When machining aluminum you want uncoated polished carbide, usually a cutter with a forward cant like the FM45.
