Abstract: PROBLEM TO BE SOLVED: To provide a tool holder, and a tool system including the tool holder and a tool.SOLUTION: The tool holder (2) is achieved to be tightened to a machine tool and also to reversibly accept a radial tool (4), in particular to accept a milling cutter. The tool holder (2) is achieved by three parts including a rear mechanical part (6) made of malleable elastic tool steel for reversibly tightening to the machine tool, a front clamp part (10) made of the tool steel for reversibly accepting the tool (4), and an intermediate part (8) disposed between the rear mechanical part (6) and the front clamp part (10) and made of a heavy metal, in particular a solid hard metal. Since the heavy metal has a larger density than that of the tool steel, the tool holder (2) can better absorb force occurring during milling. Thus, the milling with reduced use of a cutting tool can be achieved, thereby achieving a long service life as a result.
