Effortless Drilling in Concrete - The SDS plus-5 Drill Bit allows for effortless drilling. For smooth work, the carbide plate is grooved and bears notches that penetrate material more easily and prevent jamming in concrete. Drill guidance for easy starts without jarring or wandering is provided by the Activeteq centring tip, which keeps the drill in place for a precise hole diameter. Furthermore, AWB brazing and hardening technology reduces vibration during drilling to minimise strain on the user. The bit is intended for use on masonry and concrete. It is compatible with rotary hammers with SDS plus holders. To achieve accurate results, the visibility of the wear mark indicates if the diameter of the hole is still in tolerance for metal anchor setting. As proof of quality, the drill bit bears the test mark of the PGM Masonry Drill Bit Association Board, guaranteeing compliance with tight tolerances, exact drilling and the firm hold of fixings. It is made in Germany. Fits all SDS plus r
