PGM tested drills: they live up to their reputation!
The drills manufactured by Alpen bear the mark of conformity of the
Prüfgemeinschaft Mauerbohrer e.V. (PGM), which is granted
only to selected manufacturers.
Drills which bear this mark are guaranteed to conform to strict criteria
regarding the diameter of the blanking die, its symmetrical soldering,
and the concentricity of the drills.
Therefore only PGM tested tools may be used for drilling holes for
anchor connections which are liable to approval.
