More than 40 years experience with drilling and drill bits mean that we can competently solve problems for you. The use of quality-critical work procedures, such as inert gas high-temperature brazing up to 1,120єC, austempering and shot-peening, ensure a long tool life. In addition to established production processes, quality assurance is of great importance. Inspection of incoming materials, intermediate checks, final checks and regular drilling and testing under extreme contitions provide new knowledge resulting in assurance and improvement of procedure as well as materials.
