Abstract: A milling tool comprising a cylindrical shaft part, which has a central axis and which is followed by a cylindrical cutting part comprising at least three circumferential cutting edges, which run helically and which are separated from one another by chip grooves. The circumferential cutting edges continue via cutting edge corner regions in end cutting edges, which run essentially radially and which subsequently slope away from the milling cutter face towards the central axis from radially outer end cutting edge sections, in each case with a cutting edge section, which is formed by ground-in end pockets. The cutting edge section slopes continuously all the way to the central axis. In the region of the milling cutter core, it is formed by a point thinning, which is introduced into the end pocket and by means of which a center cutting edge is created. Also, a method for producing the milling tool.

Abstract: A milling tool for producing chamfer surfaces at workpieces. It has a cylindrical shaft and a cutting part, which has at least two end cutting edges, which are each located on a cone jacket surface and which run in a spiraled convex manner in the direction of rotation, and which each extend from a radially outer cutting corner to an inner cutting corner on the end side. To broaden the area of application of the milling tool to processes, such as the “ramping” or the linear diagonal plunging, respectively, the circular milling, the spot-drilling, or the waterline milling, the end cutting edges merge at the inner cutting corner into center cutting edges, which are located on a cone jacket surface with a tip angle of above 180°, and which run with a positive chip angle into a region of the milling cutter center located in the milling cutter core.

Abstract: An adjustment device for adjusting the position of at least one cutter of a fine machining tool, particularly a reamer, with respect to a cutter support (ST) is described. To allow the cutter to be adjusted as precisely as possible, the cutter support (ST) borders at least one pressure chamber (DK) which is arranged in the adjustment direction of the cutter (S) with a displacement with respect to it and which is filled with a pressure medium which can be placed under pressure using a pressure generation device. Between the cutter (S) and the pressure chamber (DK), a cutter support wall (W) remains which is elastically deformable upon application of pressure by the pressure transfer means to adjust the cutter position.
