The Irwin Speedhammer Max drill bits are certified by the Association of Wall Drilling (PGM®). The advantages of PGM®-marked drill bits include: tight tolerances for diameter and symmetry of the carbide tip ensure the accuracy of the drill hole, secure anchoring and fastening, continuous quality assurance, as well as safety and trust in the product. Compliance with these criteria is continuously monitored by PGM®, making the drill bits safe and reliable.
