The supporting cylinder (2) on the carriage body (1) acts as guide for slidable drill motor (3) and is allocated vee-guides (5) on the carriage body to guide the drill slide (6) mounted on the supporting cylinder (2). The cylinder (2) also carries return pulleys (7) for the steel wire (9) and in this ways doubles the drill support travel both ways.
