摘要： Cutting tool holders are disclosed that include vibration dampening elements. The vibration dampening elements may extend parallel to a longitudinal plane of the cutting tool holder. The vibration dampening elements allow the cutting tool holders to have a smaller width while still providing higher grooving depth.

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 rotary cutting tool includes a main body, a shank portion having a rearward end, and a flute portion having a forward end with one or more flanks. One or more connecting fluid holes are in fluid communication with a central fluid hole and terminates at a flank at the forward end of the cutting tool. One or more twisted fluid holes extend through a lobe in the flute portion and terminates at a flank at the forward end of the cutting tool. A cross-sectional shape of the connecting fluid holes and the twisted fluid holes is selected to provide enhanced delivery of fluid to the cutting edge. In one aspect, the rotary cutting tool is a modular drill and the flute portion has a pocket for holding a replaceable cutting insert.

摘要： A tool holder for rotary cutting tools is described. The tool holder comprises an axis of rotation, a body having a receptacle for the rotary cutting tool, the receptacle extending coaxially with the axis of rotation, and at least one coolant channel terminating in an opening and adapted to conduct coolant to the rotary cutting tool via the opening. The coolant channel extends through an axial protrusion and the tool holder has an adjusting mechanism which is adjustable between a first position, in which the opening is at a first radial distance from the axis of rotation, and a second position, in which the opening is at a second, different radial distance from the axis of rotation, the axial protrusion being elastically deflected in the second position relative to the first position by the adjusting mechanism.
