Now it maters on the surface you are trying to use Raster on that you would use a face mill. As face mills do not like to plunge as that are not mad for it.
Another thought you gave us a face mill number who makes it. you may want to the vendor site and see if you can get a tool profile from them being a DXF or STP if this is newer Mastercam. or draw a custom profile.
there are some thoughts to start with.
