Milling tools monoblock \ Technical introduction – monobloc milling

high-performance coatings for milling tools

coatings act as an insulation, they form a protective layer between the workpiece and the milling tool. they protect the cemented carbide against e. g. heat or abra-
sive wear. the hard layer increases the surface hardness of the tool, for example, and signifi cantly reduces the friction coeffi cient compared to uncoated cemented
carbide. other properties may be:
 higher heat resistance
 higher cutting speeds and feed rates
 higher capability for dry machining
 longer service life
