A cutting tool, in particular for machining metal, is described. It comprises a tool main body that has at least one interface for receiving a cutting insert that can be attached to the tool main body. At least one cooling duct is provided in the tool main body and has, at its end on the interface side, an outlet section with an elongate outlet cross-section on the interface side. The tool main body is manufactured at least in sections by means of a generative manufacturing process. A method for manufacturing such a cutting tool is also presented.

The present invention concerns a pressed cutting tool comprising a variable core diameter, a mold and a method for producing the cutting tool by pressing. Said cutting tool preferably comprises a shaft and a part comprising one or more helical flutes, wherein low points or lines in said flutes define the shape of said core. In a preferred embodiment, said core is conical. In a preferred embodiment, said cutting tool is an end mill and/or a drill.

In a T-shaped tool (10) in which a head (30) having cutting edges (36, 38) and a cylindrical shank (20) are fastened together: the shank comprises a super-hard alloy, and an engaging portion which engages with a tool main body is formed in a distal end portion thereof; the tool main body comprises a steel material, and an engaged portion which engages with the engaging portion of the shank is formed therein; and the engaging portion and the engaged portion are fastened in such a way as to be retained and prevented from rotating.

A machining tool having has a body that includes a central tubular portion forming a duct centered on a longitudinal axis. A peripheral tubular portion is coaxial with the central tubular portion and surrounds the central tubular portion. A first machining stage has a first arm and a second arm that extend on either side of the central tubular portion. The first arm and the second arm each have a machining member at the end thereof. The first arm and the second arm are each integral with the central tubular portion and the peripheral tubular portion. The machining tool body also includes a baseplate. The peripheral tubular portion has at least one linking arch connecting the first arm and the second arm and bypassing the central tubular portion.

A drill bit in conjunction with a hammer-drill to penetrate composite metal and non-metal structure or structures including, for example, thick metal or rebar encountered during concrete, rock or masonry boring operations without requiring a change in drill equipment.

Method for producing a machining segment (51) for a machining tool from a powdered or granular first matrix material (56), first hard material particles (57), which are arranged according to a defined first particle pattern, and second hard material particles (58), which are arranged according to a defined second particle pattern, the machining segment being connected by an underside (61) to a basic body of the machining tool. The machining segment (51) has on the side surfaces a projection of the second hard material particles (58) with respect to the first matrix material (56).

A cutting tool comprises a shank having an insertion portion protruding from a shank main body, a head in which an insertion hole into which the insertion portion is inserted is formed, and a spacer disposed in a gap between the shank main body and the head. The insertion portion has a tapered outer circumferential surface which gradually decreases in diameter from the other side toward one side in the axial direction. The insertion hole has a tapered inner circumferential surface coming into surface contact with the tapered outer circumferential surface. A head end surface of the head which faces the other side in the axial direction comes into surface contact with a surface facing one side in the axial direction of the spacer.
