DLC (Diamond-like Carbon) Coating Endmill Series AURORA Coat Endmills
I
For Copper Electrodes
■ Features and Applications ● Very smooth AURORA Coat results in low adhesion as well as a good surface finish ● With lower cutting forces and high rigidity, this series is suitable for low rigidity machines ● Available in 2- and 4-flute square type as well as ballnose type endmills ● Added R0.05 to R2.00mm long neck ballnose endmills for machining copper electrodes
