Suitable for cutting material: it is suitable for through-hole machining of difficult to machine stainless steel, showing excellent machining characteristics and durability. It is suitable for all kinds of stainless steel, heat-resistant steel and nickel chromium manganese steel, especially in high speed and high dilution conditions can exert excellent cutting performance.-|-_-|-
