7 pieces. Solid hammer drill bit with aggressive 2-cutter head, lathe centre and Vario spiral conveyor with core reinforcement for a significantly improved drilling speed. Specially optimised for cordless hammer drills.
Noticeably quicker drilling
Optimum 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
Due to special self-centring point.
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 protection against breakage.
- Reduced friction
- Increased stability
- Maximum transmission of impact energy
NoticeØ 4.8 and 6.3: Special drill bit for SFS spike mounting system.
Caution: With long drill bit lengths, pre-drill using a short drill bit of the same diameter.
