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.):
