How close to 90 degrees is the 390 series? What kind of a shoulder finish should I expect with multiple depth cuts? When should I choose a 390 over a 490 cutter? Thanks.

Both the CoroMill 390 and CoroMill 490 are true 90 degree mills. If you are looking for less than .001" mismatch on a shoulder then I would use the CoroMill 490. You can achieve about .0006" if you minimize your step to less than .080" doc. I would use the CoroMill 390 when needing a square shoulder mill with larger than .200" doc, ramping and plunging capabilities. The current CoroMill 490 can not handle those type of operations.

Hi!!
"Hi Coromant_Chicago. What cutting parameters did you use? Also, what kind of material and grade of insert did you use? Thank you. - Jeffrey"
I have the same questions... :)
I have tested the same cutter in stainless steel a few days ago, but having problems with heat. The cutter is warming up, but in case of water cooling 2030 is chipping.
Please send some info...
Cheers,
Krisz(Coromant)

I was not at the filming of this test cut so I can only guess. If you are working with stainless steel I would try our newer 1030 grade. It has a thin sharp coating and works very well!
