Abstract
The invention relates to a cutting tool having a substrate base body and a single or multi-layered coating attached thereupon, wherein at least one layer of the coating is a metal oxide layer produced in the PVD process or in the CVD process and the metal oxide layer has a grain structure wherein there is structural disorder within a plurality of the existing grains that are characterized in that in electron diffraction images of the grains, point-shaped reflections occur up to a maximum lattice spacing dand for lattice spacing greater than dno point-shaped reflections occur, but rather a diffuse intensity distribution typical for amorphous structures.
