Product description
- Maximum drilling speed thanks to reduced friction and improved impact transfer, courtesy of the special geometry of the chisel-shaped drill chuck
- Stable and durable centre point for highly accurate pilot drilling
- Fracturing mechanisms create micro-cracks in the material for noticeably faster drilling progress
- The risk of snagging on concrete reinforcement is significantly reduced thanks to the enlarged reinforcement grooves
- The twin-helix auger with screw-type geometry and a reinforced core ensures rapid removal of drill cuttings and maximum fracture resistance
- For use in concrete, masonry, natural stone and granite
