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 the tool (1), in particular the collet (2), for mediums, in particular for coolants and/or flushing agents and/or lubricants. Said 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).
