Mapal has added a further cutting edge to the Drill-Reamer in order to produce fitting bores even more accurately using just one tool and developed the Tritan-Drill-Reamer. The tool with internal cooling for tapping, drilling and reaming is available in 3xD and 5xD lengths. With six guiding chamfers for excellent guiding properties, precision-ground chip flutes with matching groove shape for good chip removal and a selfcentring chisel edge, the new Tritan-Drill-Reamer is convincing all around. The self-centring chisel edge ensures good positioning accuracy and improved tapping behaviour. Three cutting edges guarantee optimal roundness of the bore and highest performance. The reaming cutting edge produces high-quality surfaces.
