Noticeably quicker drilling
Optimised tip geometry and asymmetrically placed elevations on the cutting edges ensure improved traction.
Optimum drilling performance when striking reinforcing bars
Reinforced tungsten carbide elements with noticeably larger chamfers considerably reduce the possibility of the drill bit catching on to reinforcing bars and increase resistance.
By means of special self-centring tip.
Vario conveyor helix with core reinforcement and back that narrows at the front and widens at the rear, as well as sharper angle at the helix end.
Considerably improved drilling speed and dust removal while at the same time offering increased security against breakage.
