Abstract
A machining tool for deburring boreholes, which lead laterally into a recess, comprising: a shaft; a cutting head with at least one circumferential cutting blade associated with a chip groove and having a cutting edge extending, at least in sections, in an axial direction, and which can perform a cutting process by virtue of relative movement between the tool and a workpiece, and which lies on a virtual cylindrical rotation surface; and at least one cutting-blade-free and chip-groove-free surface area; at least one fluid channel closed on the cutting head side, extending through the shaft into the cutting head; and at least one branch channel with an outlet opening. The outlet opening is in a dynamic pressure active surface radially set back relative to the virtual rotation surface, and is larger than a flow cross-sectional area of the at least one branch channel at the outlet opening.
