Hammer Bits

Use of hammer bits
Hammer bits are recommended for drilling holes in brickwork and concrete with fast and reliable results. For the proper installation of components, it is necessary to use drill bits from a certified manufacturer. Using drill bits from monitored production is the only way to guarantee that the bore area will not be exceeded and that consistently good results will be achieved. Bits with too much true-running deviation or too high tolerances in the tungsten carbide tip can result in drill holes with not enough grip, for instance, for an anchor. In extreme cases, the installed elements will become loose and cause severe damage. It is therefore recommended that you only use drill bits that have been manufactured in accordance with the guidelines of the Prüfgemeinschaft Mauerbohrer (PGM), an independent institute. You can recognise this by the PGM quality mark.
