摘要： The invention relates to a coolant turbine for a rotary cutting tool, a rotary cutting tool, a coolant turbine module, and a method for operating a rotary cutting tool. The coolant turbine comprises an annular turbine base body having a first front face, an opposite second front face, and a plurality of coolant passages, which are arranged so as to be distributed around a central axis of the turbine base body, said passages having a coolant inlet and a coolant outlet, each of which extends through the turbine base body at least in portions in such a way that the turbine base body can be set into rotation by a flow of coolant.

摘要： A modular cutting tool includes a cutting head, a shank and a mechanism which assists in assembling and locks the cutting head to the shank. The cutting head includes a cutting portion rotatable about a central longitudinal axis and a cylindrical skirt extending axially from the cutting portion and terminating at a contact face disposed perpendicular to the longitudinal axis. The skirt has a number of curved inner surfaces which generally define a bore disposed about the longitudinal axis. The shank includes a cylindrical portion of a first diameter disposed about the central longitudinal axis and a central protrusion disposed in the bore of the cutting portion. The central protrusion has a second diameter less than the first diameter and extends longitudinally from a contact face disposed perpendicular to the longitudinal axis at a leading end of the cylindrical portion.
