I looked and that Octomill seems to be just another one of myriad products Mitsubishi pushes out, then no further development of grades and chipbreakers. Iscar is famous for this too, putting out new product to let unsuspecting customers do their testing and then discontinuing development if it isn't working. It is also a 45º lead angle face mill, not unlike a Walter F4080 or older F2280.
In the insert nomenclature you posted, the complete OEMX1705EER1-JS F7030 is the designation for the insert and all you need.
O = octagonal shape
E = 20º side clearance angle
M = tolerance, sintered to size, not ground
X = Proprietary hole or top form geometry
17 = inscribed circle size of the insert. man, those are HUGE for a small cutter!
05 = thickness
EE and R1 relate to the edge hone and any wiper flat on the cutting edges.
JS = the top form geometry a.k.a. chipbreaker shape of the insert. JS is common "general purpose" for Mitsubishi.
The other numbers you had are internal, though the AOP43 is very likely a batch code for date and location of manufacture.
In the cutter designation 05 means a 50mm diameter, 03 probably means 3 insert pockets and AR likely just means right hand cut. I can't picture them getting any more than three pockets in a 50mm/2" cutter body with such a large insert. The other numbers are also just internal product codes.
The only inserts for that cutter I see listed on Mitsubishi's website covering SA is what you already have, and one cermet grade that may stand a better chance of working.
OEMX1705ETR1 (flat top, no chipbreaker) in grade NX4545. The have one other coated carbide grade in addition to the F7030 you have, but the VP15TF is really for stainless steels and superalloys.
With the same 2HP I have and that material, you really don't want the F4041 shoulder mill for this application. You want to reduce the force required so lead angle face mill is what you want. Looking at Mitsubishi's offering, they are REALLY weak in carbide grades for steels. That's the strong suit for Walter, for sure.
Keep your eyes open for an F2280 or F4080. There are two inserts sizes, and bodies and inserts must match. The cutter designation end in "....03" for the smaller ODMT0504ZZN-D57 or ends in "....04" for the larger ODMT0605ZZN-D57. If you see any other brands that you can get a steady supply of inserts, let me know and we'll look for something in that brand, though it will be tough or impossible to match that WKP25S grade for tool steels.
Good luck!
Incidentally, you said you got some products shipped to you by Carbide Depot here in the US. They are a fully authorized Walter distributor and can get any of the products to you.
