The article presents the results of the study aimed at solving the problem of drilling with portable pneumatic punchers. The problem lies in the simultaneous provision of considerable forces applied by the operator to the perforator crank and the effective damping of its vibration. The authors offer a new concept of designing drilling equipment consisting of the combination of a new design of the vibration damper crank not conjugated either with the case or with a working tool, and a light feeder providing the maximum drilling speed without necessity for the operator of using physical forces.
