Abstract: A rotary drilling tool (10) has a cutting head (12) with at least one tip (22) and a front-facing main cutting edge (24) defining a maximum diameter (D) of the cutting head (12). The cutting head (12) has an undercut (38) with a radially inwardly springing ledge (44) with a rear-facing blade (42) provided for cutting when pulling the rotary drilling tool (10) out of a workpiece. Furthermore, a method is provided for producing a through-hole in a workpiece by means of such a rotary drilling tool (10).

Abstract: A cutting tool (2) is specified with a cutting region (4) that comprises a substrate (12) onto which a coating (10) is applied, which coating (10) is subsequently processed, whereby a sharp cutting edge (8) is formed. Furthermore, a corresponding method for the manufacture of the cutting tool (2) is specified. By means of the sharpening of the cutting edge (8) after the coating rather than before, a particularly sharp cutting edge (8) is formed, whereby the precision of the cutting tool (2) as well as its service life is improved.

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).
