Premium multi-cutter for concrete and reinforcement. Highest service life and extremely resilient to wear. Particularly powerful and rugged multi-cutter with patented Trijet tip. With recessed carbide tip for extreme resilience in reinforcement steel and powerful drilling progress. Lowest costs per hole. Highest effectiveness and speed thanks to Trijet tip plus optimized helix design. Best possible drill dust transport without risk of inflagration thanks to large-volume, low-vibration Twinmax 3D helix, also in deep holes. Lowest vibration thanks to computer-simulated helix reduces the load on the user. Particularly easy positioning; avoids spalling even after drilling many holes thanks to double centering tip.
