Yes, that is what you have. If you want to try to modify the end mill, do you have a bench grinder or hand grinder and steady hands? If you flatten the leading cutting surface so make it closer to 90 deg that should help, only needs the first .005"-.010" of the edge, just helps keep it from biting into the work. The same grind is used to modify tools for soft materials and plastic to keep the bit from cork screwing into the part.
