To overcome this restricting
dualism, various cutting tool materials are manufactured
as composite materials. In particular wider and wider are
applied the tools made of HS-steel and tungsten carbide
with wear resistant coatings, as well as the tools with
modified superficial properties [1, 2, 4-7]. Wider
applications have also found layered cutting materials, in
which layers made of tough carbides as well as
superhard and high heat-resistant ceramics are combined
[8]. Application of a tool material capable to resist
thermal weakening and intensive destruction of the tool
cutting part would be a simple solution of the problem
