Dual-cutter for concrete and reinforcement steel. Extremely robust with long service lilies thanks to the patented drill head. With recessed carbide tip for extreme resilience in reinforcement steel and powerful drilling progress. Best drilling process thanks to the optimised carbide cutting edge. Twin max 3D helix for highly effective drilling dust transport and minimal dust INFLAGRATION even in deep holes. Low vibration reduces the load on the user. Particularly easy positioning and avoids spalling even after drilling many holes thanks to double centring tip.
