    Abstract: The invention relates to a rotary tool as well as to a carrier and a cutting insert of such a rotary tool. The carrier comprises a seat, which comprises several lateral surfaces, between which the cutting insert can be inserted. The cutting insert comprises, for each of the lateral surfaces, a contact surface which abuts against the respective lateral surface in an inserted state. At least one coolant channel is formed, which comprises a first partial channel and a second partial channel, which adjoins the first partial channel, wherein the first partial channel proceeds within the carrier up to an outlet opening, wherein the second partial channel proceeds within the cutting insert from an inlet opening up to a coolant outlet, wherein the outlet opening and the inlet opening form an interface for transferring coolant from the carrier to the cutting insert. The outlet opening is arranged in one of the lateral surfaces and the inlet opening is arranged in one of the contact surfaces.

    Abstract: The combination tool (2), in particular a drilling/chamfering tool, comprises a drill (6) extending in the longitudinal direction (4) with a clamping sleeve (8), which is designed to receive the drill (6) and fasten the drill (6) at a variable length and which has a holding seat (38) for a cutting insert (12). The drill (6) comprises a cutting region (22) provided with grooves (14), wherein the grooves (14) extend helically and are formed between two grooves (14) drill backs (18). At least one of the drill backs (18) is partially flattened to form an adjustment surface (16) for the cutting insert (12), wherein the adjustment surface (16) extends helically. As a result, a length adjustment over a large length range is made possible independently of the twist angle (γ).

    Abstract: The drill head (2) extends along a rotational axis (24) in the axial direction (22) and has a central area (6) on the front with first main cutting edges (26), an intermediate area (8) connecting thereto, and an outer area (10) in turn connecting thereto with second main cutting edges (30). The intermediate area (8) in this case expands in the axial direction (22) toward the outer area (10) and in particular forms an expanding conical shell. A centering effect is hereby achieved via the intermediate area (8).

    Abstract: The radial run-out tool (2), particularly a drill or a cutter, has a basic body (12) extending in an axial direction (4) and comprises at least two chip grooves (14), to which a guide chamfer (22) is connected in the rotational direction (24), with a ridge (15) being formed between them. A radial clearance is connected to the guide chamfer (22). In order to enable simple and economical production of such type of radial run-out tool (2), an unprocessed rod (30) is ground non-concentrically, in a first process step, such that a radius (R) of the unprocessed rod (30) varies, depending on the angle, between a maximum radius (R2) and a minimum radius (R1). In a second process step, the chip grooves (14) are grounded down such that the guide chamfers (22) are formed at the positions with the maximum radius (R2) and the radius (R) is subsequently reduced downstream of the respective guide chamfer (22) in order to form the radial clearance (28).
