With good milling and cutting performance, carbide can run at higher speed than high-speed steel. The passivation treatment greatly increases corrosion resistance and wear resistance.Suitable for cutting materials with hardness below HRC55, such as aluminum, aluminum alloy, copper, magnesium alloy, etc.. The end mill has an extended neck (long reach) that provides additional reach and clearance for machining deep or hard-to-reach areas.
