Heller hammer drill 3 cutter drill set 5/6/8/10/12mm, 7 parts

The Trijet Ultimate SDS-plus hammer drill is even more robust and faster than its predecessor. Equal height cutting edges with reverse curvature, the newly developed cutting geometry with reinforcement protection chamfers, reduced face surfaces and the optimized helix guarantee even better performance, making the Trijet Ultimate our best hammer drill. In total, the Trijet Ultimate is therefore 4 x more robust, 10% faster in concrete and 35% faster in reinforcement, resulting in a very long service life with up to 1,500 drilled holes.
