The M35 containing cobalt alloy quality steel milling molding, overall after vacuum heat treatment, import Hss-co with high cobalt content high hardness steel, in the drilling of the workpiece material have excellent processing performance. More high wear resistance and low friction coefficient, increase productivity and reduce the processing cost of the unit hole,
is processing stainless iron metal is the most ideal drill can also drill for wood, aluminum alloy.
