New PGM explain video clip
Heller holds a certificate from the independent Prüfgemeinschaft Mauerbohrer e.V. (PGM) for its products. PGM defines stringent requirements for secure drill-hole/anchor connection. Through monitoring and tests, PGM ensures that the user is only offered drill bits that are made to suit an application using approved anchors.
Only a few manufacturer in the world are authorised to carry this seal, which every user of hammer or percussion drills will have seen before. Bits with this seal deliver what many others claim: geometrically precise holes, which offer maximum grip for the anchors and maximum safety for the user.
