Proposed is a tool with a tool insert (53) for machining workpieces, comprising a collet (2), designed for manual interchange of tools and for securing in position the tool insert (53) in a tool spindle (89), comprising at least one channel, penetrating essentially in the axial direction of the tool (1), in particular the collet (2), for mediums, in the particular for coolants and/or flushing agents and/or lubricants. The tool is characterized in that a second channel (7, 7'), which is separated from a first channel (5) and which runs essentially in the axial direction, is provided for mediums, in particular for coolants and/or flushing agents and/or lubricants in the collet (2), and that different mediums can be conveyed in the channels (5) and (7; 7'); and that they empty into a mixing device (85).
