General purpose wear resistant turning grade. The multi-layer coating includes aluminum oxide to add additional heat and wear resistance. It is used to machine steel at lower speeds than TN15. This turning grade is for demanding metal removal operations, including cutting through scale at low speeds through heavy interruption, and problem machining of stainless steel at low speed and poor rigidity.
