5/16" Variable 3 Flute End Mill for Aluminum ZrN

Our unique geometry includes a .003-.005 corner radius extending tool life, a highly polished flute gullet improving chip evacuation, variable helix multi index flutes eliminating vibration and harmonics and Zirconium Nitride coating for hardness and lubricity. This design allows a heavy chip load per tooth for maximum material removal in aluminum and unmatched performance. Can be used to rough or finish, slot or profile in aluminum and plastics.
