I ended up using the apt tool with the indexable tips. I went with the alu inserts because they had a nice sharp edge. Diameter 25mm total length 200mm cutting flute 12.5mm.

worked great, only real down side was the small cutting flute. Those frog tools solve that problem but way too much cash. Anyway the majority of cutting time was spent 3d profiling and the frog tools can't help with that. So overall I would recommend using an indexable tool like this for milling insulation foam.
