    摘要： A cutting insert for use in a drilling tool includes two end faces disposed perpendicular to an insert axis and a plurality of side walls connecting the end faces. Supporting surfaces for bearing against corresponding mating supporting surfaces of a cutting insert receptacle of the drilling tool are formed on at least two of the side walls arranged in a rear region of the cutting insert. A main lip for machining a workpiece to be drilled is formed on at least one side wall arranged in a front region of the cutting insert. The side walls having the supporting surfaces are arranged in such a way that the cutting insert can be inserted into a trigon cutting insert receptacle in an accurately fitting manner.

    摘要： A tool holder has a body with a spindle side for fastening the tool holder to a spindle of a machine tool and a tool side for accommodating a tool and has a lubricating media passage from the spindle side to the tool side that contains a lubricating media bush adjustable in the axial direction in the body. The lubricating media bush opens out on the tool side of the body, wherein a guide for the lubricating media hush is provided in the body. The guide contains a fitting section in which the lubricating media bush is adjustably guided, wherein a seal is provided which seals the lubricating media bush relative to the body.

    摘要： A double-sided, nonagon cutting insert includes a top surface, a bottom surface identical to the top surface, nine side surfaces that are identical to each other, a cutting edge formed at an intersection between each of the nine side surfaces and the top and bottom surfaces for a total of eighteen cutting edges, and nine corner radiuses identical to each other, each corner radius extending between the top and bottom surfaces and each of the nine side surfaces. Each cutting edge has a non-symmetric profile with respect to a central, longitudinal axis. The non-symmetrical profile of the cutting edge has the technical advantage of providing a variable cutting force, particularly during fine finishing cutting operations.
