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 guid more→ance 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. 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 …

The Irwin HSS Pro TiN drill bits are primarily designed for drilling metal and harder, tougher alloys. Compared to traditional HSS twist drill bits, speed can be increased by 40 -60% and feed by 10 -2 more→0% without reducing the life time of the drill bit significantly. TiN is also a poor conductor of heat, so the heat generated during the drilling process is diverted into the chips and coolant and less into the drill bit. These drills have a 135 split point grinding tip which ensures perfect centring and reduced drilling pressure. The drill bit body is manufactured from high quality HSS steel coated with 2.5 Titanium Nitride (TiN), the TiN coating has a hardness of app. 80 HRC and is very resistant …
