Noticeably quicker drilling
Optimised tip geometry and asymmetrically placed elevations on the cutting edges ensure improved traction.
Optimum drilling performance with reinforced chamfers
Reinforced hard metal elements with noticeably larger reinforcement chamfers considerably reduce the possibility of the drill bit catching on reinforced chamfers and increase resistance.
Precise drilling
By means of special self-centring tip.
Vario spiral conveyor with core reinforcement and back that narrows at the front and widens at the rear, as well as sharper angle at the spiral end.
Considerably improved drilling speed and dust removal while at the same time offering increased security against breakage.
- Reduced friction
- Higher stability
- Maximum transmission of impact energy
- Dia. 4.8 and 6.3: Special drill bit for SFS spike mounting system.
