  • Drilling milling tool and methods for producing a through-hole
    Patent number: 10105763
    Abstract: A drilling and milling tool (100) for a metallic workpiece, with a drilling and milling shank (120) having a plurality of circumferentially-cutting cutter tips (151, 152, 153, 154) and a plurality of front-end-cutting cutter tips (131, 132). At least one of the front-end-cutting cutter tips (132) is, at the same time, a circumferentially-cutting cutter tip whose radially outermost cutting point or cutting edge section projects, in the radial direction (R), beyond the circumferentially-cutting cutter tips (151 152, 153, 154). The circumferentially-cutting cutter tips (151, 152, 153, 154) are made with straight cutting edges and together these cutting edges produce a cylindrical cut contour. Two methods that can be carried out with the drilling and milling tool (100) for producing a through-going bore in a metallic workpiece.
