Drilling tools since 1910. Since the company was founded in 1910 by Robert Berger Sen. and his sons Paul and Robert Jun. in Solingen, we have been producing special tools for drilling and manufacturing ceramic-bonded abrasive discs – now for more than five generations. In addition to our drilling tools, we produce concrete millers and iron tools for joints for road restoration and offer our customers all standard services and custom work in the field of metal processing. The stainless steel door fittings made in the 1990s are further testimonials to our manufacturing capabilities. Even today, you can still find these fittings in the Bundestag, the Federal Chancellery, the Hotel Adlon, the Neue Messe München (exhibition centre in Munich) and the Düsseldorf Stadttor, to name just the most well-known places.
