FAQ: Where is the need to use drill bits with PGM mark required?

The European Technical Approvals for anchors and their installation instructions demand the use of suitable drill bits. But how can such drill bits been identified under site conditions? For drill bits with PGM mark the installer can rely on their suitability for safe anchor fixings. This is nor the case for drill bits without mark. Also the German approval body for anchors Deutsches Institut für Bautechnik (DIBt) recommends in its guideline for anchor installers the use of PGM marked drill bits.
