ABSTRACT:
A rotary percussion blow assisted drill has an axially extending shank (1) with at least one main helically extending groove (4) in its axially extending outside surface (2) for conveying drilled material along the shank. A cutting plate (6) with hard metal cutting edges (7) is located in a cutting head end region (10) of the shank. The cutting edge (7) of the cutting plate (6) projects axially outwardly from a cutting head end face (3) of the shank (1) and the opposite ends of the cutting plate project radially outwardly from the outside surface of the shank. At least one pin-shaped guide element (11) is embedded into the outside surface (2) in the head end region (10) of the shank. The guide element (11) has a central axis disposed substantially perpendicularly to the axis of rotation (A) of the shank (1) and has a free end face (12) located radially outwardly from the outside surface of the shank by a dimension less than the dimension which the ends of the cutting plate are spaced radially outwardly from such outside surface.
