    摘要: A tool head includes a main body having a nominal diameter, a face end center formed on the main body, and at least two major cutting edges which each run radially outward from and adjoin the face end center. The face end center is formed by a cone of circular cross-sectional area, which cone extends from a cone apex through to a cone base.

    摘要: In order to ensure good guidance of a drilling tool at the start of a drilling operation and at the same time ensure a reliable evacuation of a center chip, in the drill bit, in a tool flank adjoining a respective main cutting edge, an additional point thinning is recessed in the region of a transverse cutting edge, which additional point thinning, extending in a principal direction from the tool flank, merges, with a convex course, into a chip flute. As a result of the convex design, an as far as possible homogeneous, edge-free transition into the chip flute is obtained. Since the point thinning is additionally made, the tool flank, even in the rear end facing away from the cutting edge, remains at a front axial position, so that a second land is effective for a reliable guidance of the bore already at an axially front position.

    摘要: A coupling point for a modular rotary which extends in an axial direction. The coupling point includes a first coupling part disposed on a tool head and a second coupling part disposed on a carrier. The coupling parts can be coupled to one another by bidirectional rotation with the formation of an interference fit which acts in the radial direction. Each coupling part includes two coupling faces which lie opposite one another and have contact regions in which the interference fit is formed. In the first coupling part, at least one of the coupling faces has at least two contact regions which are spaced apart from one another in the circumferential direction, and, to this end, at least one first clearance portion is formed between the contact regions, in which clearance portion the two coupling parts do not bear against one another in the coupled state.

    摘要: In order to achieve a long service life for a machining tool, in particular for a solid carbide drill, it is provided with a special wear protection coating. In a first method step, in order to form this coating, a first layer made of a first material is applied in the region of a cutting edge and in the adjoining surface regions, and specifically, a flank face and a rake face. In a second step, the applied first material of the first layer is selectively removed at least partially, and preferably completely, only in the region of the cutting edge. Finally, in a third method step, a second layer made of a second wear-resistant material is applied both to the cutting edge and to the face regions. In this way, a coating having a high overall thickness in the face regions is made possible, without the risk of cracking.

    摘要: A rotary tool, in particular drilling tool, extends along a longitudinal axis and has an end surface; a brad point; and at least one major cutting edge extending outward up to an edge corner. A first free surface segment adjoins the major cutting edge, and a second free surface segment in turn adjoins said first free surface segment. To keep the stress, in particular the wear, low in the region of the end surface, the first free surface segment has a lower average abrasiveness than the second free surface segment.
