摘要：
The invention relates to a cemented carbide material having a hard phase including tungsten carbide (WC) grains having an average grain size of 0.3 microns or less and also including cobalt (Co) as a bonding phase. The material also includes cobalt tungsten carbide grains that have a smaller average grain size than that of the tungsten carbide grains. The cemented carbide material has use, among others, in making cutting tools.
