Application tips hammer drilling
If you need drill masonry and concrete, it is advisable to use hammer bits to achieve fast and reliable results. To ensure correct installation of construction parts, it is important to use drills from certified manufacturing. Only the use of bits from audited manufacturing can guarantee that the diameter of a drill hole is not exceeded, and thus ensure sustainably good results. Drills that are too far out of round, or with excessive tolerances in the carbide cutting edge can lead to drill holes that do not give a plug sufficient hold. In the worst case, installed elements will come loose causing major damage.
We thus recommend the use of bits that comply with the rules established by the Prüfgemeinschaft Mauerbohrer ((PGM - Wall Drill Test Association), an independent institute. You can identify these bits by the PGM kite mark.
