End mill suggestion for special material

Hi,

I am trying to cut this special material

Its formed with rubber (red/black) sheet with sponge (purple)

Total thickness is about 2.0mm and I want to make clean edge cut with CNC

One more thing to add is that rubber side will always touching the CNC bed side

I know tangential knife or drag knife will do the job but that's not an option that I have at this moment.


Please feel free to suggest me anything.

Thanks,

Another close look of material

In this picture, red part is rubber, and orange part is sponge.
