Abstract

A cutting chisel holder which is controlled by pressure and constructed as a rotary drill head which can be precisely adjusted by hydraulic means has a cutting chisel, which can be clamped in, with a base and a driven member which is movable relative to the base, and has a pressure chamber arranged between the base and driven member, as well as a pressure medium feed. The driven member moves parallel to itself under the influence of the pressure medium and, in doing so, causes a movement of the cutting chisel on a curved path extending approximately vertically to the axis of rotation of the drill head by parts acting mechanically without friction.
