Technical requierements for drill bits

The geometry of the drill bits used for anchor fixings influences the safety and performance of the fixing. Important Parameters of the drill bit are:

  • Diameter of the cutting plate
  • symmetry of the cutting plate
  • height of the cutting plate
  • run-out tolerance of the drill bit.

The complex geometry of drill bits with multicutters needs a special assessment.

All these aspects, including the quality potential of the drill bit manufacturer, are covered by the certification mark of the PGM (Prüfgemeinschaft Mauerbohrer e. V.):
