Abstract
The present invention relates to pneumatic impact devices and can be used to the best advantage for making holes in compacted soils. The device is provided with a hollow casing which accommodates a stepped ram with the maximum-diameter step in its front part. This step has longitudinal channels which open at one end into a working chamber defined by the maximum-diameter step and the side walls of the casing and serving for receiving compressed air from the compressed air line, with the air moving the striker to impart a blow after which it is discharged through holes in the casing.
