1.Widely used in the processing of high-hardness materials, such as copper, cast iron, carbon steel, and mould steel etc.
2.Recommend to select the size with minimum overhang required as long overhang is vulnerable to vibration, and thus need to reduce RPM and the feed volume
3.Need to adjust RPM and feed rate reasonably accoring to cutting depth, the machine rigidity and other conditions of usage
4.With highly heat-resistant ALTIN coating, can be used for high-speed processing
5.High toughness, using grain-sized carbon tungsten as the raw material
6.Help to increase the smoothness, reduce the friction coefficient,and improve the lathe efficiency, thus save more production time
