Certificates for professional tools


In addition to the sophisticated production processes, quality assurance is very important. Inspection of incoming materials, intermediate controlls, final checks and regular drilling as well as testing under extreme contitions provide new insights that help to secure and improve processes and materials.

In any case, safety is demanded!

Among others you can identify quality drilling tools by the quality mark of the independent "Prüfgemeinschaft Mauerbohrer" (PGM). Keil is a member of the founding board of the PGM (in 1987) and is authorized to use this mark.

This quality mark guarantees the conformity of our drill bits with the requirements of the German Institute for Structural Engineering (DIBt) concerning drilling holes for anchors and plugs to be fixed in concrete and brick work with general building supervision admission or a European technical admission (ETA ). Violation by non-qualified manufacturers is legally prosecuted.

What does the PGM mark stand for?

  • Selected qualified manufactures
  • Production and quality assurance state-of-the-art supervised by PGM
  • Clear marking instructions
  • Strict tolerance limits for the diameter, the symmetry of the carbide tip and the out-of-true variation
