Applicable wherever a high wear resistance and tool life are required. Only a few manufacturers are capable of producing step-hardened annular cutters. For Karnasch this is 'standard'. We produce extremely hard tooth tips (68 HRC) and still yield a flexible annular cutter. Our first-class annular cutters are equipped with the unique and patented DURABLUE- coating. This line has extreme surface hardness and the sleekness of the design yield longer tool life even under the least favorable conditions such as overhead work or dry drilling.
