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： The present invention provides a cutting insert with a lip support providing additional support for the cutting insert. The cutting insert may be secured to a pocket of a drilling tool. The cutting insert may include a front surface, rear surface, and side surfaces. Cutting edges may form at the intersection of the side surfaces and the front surface. A cutting lip may extend rearwardly from the cutting edges with a seating surface under the cutting lip. The transition between the seating surface and the cutting lip may include two chamfers separated by a lip support.
