Abstract

According to the present invention there is now provided a cemented carbide drill/endmill blank consisting of a core and a surrounding tube with improved technological properties. The difference in Co-content between the core and tube is 1-10 wt.% units and the cubic carbide content is 8-20 wt.% in the tube and 0.5-2 wt.% in the core. The invention also relates to the method of making said cemented carbide drill/end mill blank.
