Abstract: A turbine wheel for drive turbines especially of metal working machinery consisting of a disc-shaped wheel body (1) with a central bearing opening (2) and intake orifices (4) concentrically located on the circumference of a lateral disc surface (3) and of drive air channels (5) running inside the wheel body each ending in an outlet orifice (14). The outlet orifices (14) are located on the peripheral disc surface (7) where the drive air channels (5) show an inflow section (6) of approximately axial direction and an outflow section (8) running inside the disc body (1) in the direction to the peripheral disc surface (7).
