Features: Our best SDS-plus multi-cutter with the highest service life in concrete and reinforcement. The recessed carbide tip ensures maximum durability in concrete and reinforcement. Highest efficiency and speed thanks to the Trijet carbide head. Optimal dust transport without blowout effect, even in deep drill holes, due to the large-volume and low-vibration triple helix. Minimal vibration through computer-calculated helix reduces strain on the user. Particularly easy to start drilling and prevent chipping even after many drillings, thanks to the double centering tip. The Trijet SDS-plus is the most powerful hammer drill from Heller, with the highest service life in concrete and reinforcement. The patented Trijet drill head is characterized by an extremely robust and powerful drilling progress. In combination with the optimized helix design, it ensures maximum efficiency and speed, as well as minimal vibration during drilling. The Trijet SDS-plus incurs the lowest costs per drilled hole compared to other hammer drills. Application: Concrete, reinforced concrete, aerated concrete, clinker, marble, masonry, natural stone, granite.
