I have to machine some 1/8" chamfers around the perimeter of some hardened A-2 parts (56-58 RC). I will be doing this in a 20 hp. VMC with 10,000 RPM.
What would you use if these were your available cutters:
1. 90 deg carbide countersink.
2. 90 deg carbide Iscar multimaster insert cutter (looks like a 2 flute countersink or an end of a drill mill).
3. 1.25" dia Iscar octomill (uses 8 sided insert, results in a 45 degree lead angle).
What about speeds, feeds, and depth of cut?
