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.

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： A coupling part structured to engage with a complementary coupling part for interchangeably fastening a cutting head to a carrier of a rotary cutting tool. The coupling part includes a pair of coupling pins arranged opposite each other with respect to a central longitudinal axis and spaced apart from each other so as to form a receiving space structured to receive a central pin of the complementary coupling part. Each coupling pin includes a stop surface for transmitting a torque, a radially external outer surface, and a radially internal inner surface. At least one of the outer surface or inner surface is a clamping surface oriented in an obliquely inclined manner with respect to the central longitudinal axis for centering and clamping the coupling part.

摘要： The coupling part, in particular cutting head for a drilling tool for the interchangeable fastening in a coupling receptacle, has a coupling pin which is enclosed by a head support surface, wherein the coupling pin has a plurality of types of functional surfaces, namely stop surfaces for transmitting a torque between the cutting head and the carrier, and clamping surfaces for centering and clamping the cutting head in the coupling receptacle. The coupling pin has an axially front pin region and an adjoining, axially rear pin region, and the clamping surfaces and the stop surfaces are arranged in different pin regions. This decoupling and distribution of the functional surfaces to the various pin regions permits simpler production of the coupling pin and an overall more robust configuration.
