摘要： A tool for machining has a main body, a seat formed on the main body, a fastening screw, and a cutting insert. The seat has a base surface for supporting an underside of the cutting insert and a lateral bearing surface. A bore for receiving the fastening screw is formed in the base surface, the bore has a threaded bore portion and, closer toward the base surface, a thread-free bore portion. The cutting insert is fastened to the seat such that the head portion of the fastening screw is supported on the through-hole in the cutting insert. The threaded portion of the fastening screw engages with the threaded bore and the fastening screw is elastically deflected such that a thread-free shank portion bears against the thread-free bore portion on a side remote from the lateral bearing surface and is spaced apart from the thread-free bore portion.

摘要： A cutting insert has a substantially triangular or square basic shape with a top surface and a base surface that are connected together by lateral flanks. A cutting edge is formed at the transition between at least one flank and the top surface. The cutting edge extends between cutting corners, and the cutting edge has a portion that is convex in side view of a flank. The convex portion of the cutting edge is bounded on both sides by concavely curved portions.

摘要： A milling tool has a tool shank and a cutting head fastened to the forward end of the tool shank by way of a clamping connection. The clamping connection has a protrusion with clamping faces, and a recess with centering faces that interact with the clamping faces. Each of the centering faces has a first region where the centering faces are spaced from a longitudinal axis of the tool shank by a first distance and a second region at a smaller distance. The first region merges into the second region. The clamping faces of the protrusion are introducible into the recess between the first regions of the centering faces and are movable, by rotation of the cutting head about the longitudinal axis, into a clamping position in which the clamping faces interact in a force-fit with the second regions of the centering faces.
