Abstract: A tool for deburring holes is proposed, comprising a basic body, which rotates about a rotation axis of the tool and has a clamping shank, and at least one lip holder elastically movable relative to the basic body, the lip holder comprising at least one cutting element which projects radially with respect to the rotation axis and has at least one lip leading edge oriented at least partly transversely to the cutting direction, which tool exhibits improved deburring and greater endurance compared with the prior art. This is achieved by the cutting element (8, 30, 31) being made of carbide.

Abstract: A preferably rotationally driven tool is specified for the deburring of openings, such as for example bores that open laterally into an essentially cylindrical recess. The tool has a cutting head that is seated on a shaft and that has at least one cutting edge that extends, at least in segments, in the axial direction. So that the deburring can be carried out reliably and with the lowest possible expense, a radial force-producing device is integrated into the tool, for example in the form of at least one internally situated flow medium channel, from which at least one branch channel goes out that opens in the area of the cutting head or in the vicinity thereof, preferably at a peripheral distance to the at least one cutting edge, in the external peripheral surface thereof.

Abstract: The invention relates to a tool for trimming lines of intersection on the ends of boreholes. Said tool has a cutting head which is arranged on a shaft and at least one cutting edge that extends in the axial direction, at least in sections, and carries out a machining process by a relative rotational movement between the tool and the workpiece. The inventive tool is provided with a device for generating a radial force, by which means the cutting head can be radially deflected in the rotational movement thereof in a preferably controlled manner, said cutting head having a diameter (DS) that is selected in such a way that it can be introduced into the borehole with radial play (SR). The cutting head is essentially in the form of a droplet and has a smooth closed surface in the region of the largest outer diameter thereof.

Abstract: A rotationally driven tool for deburring bore holes, which join laterally into a substantially cylindrical recess. The tool contains a cutting head seated on a shaft, wherein the cutting head contains at least one cutting edge, which extends in the axial direction at least one some sections. In order to perform the deburring process reliably and with as little effort as possible, the tool contains at least one inner flow-enhancing agent channel, from which at least one cutoff channel extends, which joins in the area of the cutting head in an outer circumferential surface thereof preferably at a circumferential distance to the at least one cutting edge. Because the diameter of the cutting head is selected such that it can be introduced into the recess with radial play, the feeding of pressurized flow-enhancing agent leads to a radial excursion of the tool shaft.
