Abstract: In one aspect, cutting tools are described herein employing PCD substrates having coatings applied thereto. A cutting tool, for example, comprises one or more cutting edges including a PCD substrate and a diamond-like carbon coating adhered to the PCD substrate, the diamond-like carbon coating having hardness greater than 4000 HV0.05. In some embodiments, the diamond-like carbon coating has a thickness greater than 0.3 μm and a sp3 fraction of at least 0.85.
