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: 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.
