End Mills

Proto-Cutter Tough Cut End Mills have an eccentric grind excellent for tough-to-machine materials and hardened steel.

They are TICN coated for maximum wear resistance with staggered, serrated edges to break chips and allow for finish applications, outperforming conventional rougher/finisher end mills.
