Tool life curves were plotted for HSS, cemented tungsten carbides, coated carbides, and cemented titanium carbides. HSS tools showed a distinct inflection coinciding with the formation of a white diffusion layer. Crater wear propagation studies were carried out on all tools and in addition on laminated carbides. HSS, laminated carbide, and cemented titanium carbide show a tendency to form a closed crater, revealing that in these tools diffusion is a mode of wear.
