Claims (3)

1. Device for cutting holes in a pipeline under pressure, containing a spindle with a cutting tool located in the holder on the end face of the spindle, a mechanism for translating the spindle and a mechanism for rotational movement of the spindle, a housing as well as an element for tightly connecting the spindle to the pipeline, characterized in that the device is provided O-ring at the junction of the holder with the cutting tool in its extreme position from the pipeline, the spindle and the element of the tight connection of the spindle to t uboprovodu, wherein the annular seal is pressed against the holder with the cutting tool to the element to seal the spindle to the pipeline.
 2. The device according to claim 1, characterized in that it is equipped with a branch pipe connected to the body and to the pipe with a branch to remove the contents of the repaired section of the pipeline.
 3. The device according to p. 1, characterized in that the spindle translational movement mechanism comprises a hollow screw rigidly mounted on the housing and a nut screwed onto the screw and connected to the spindle end opposite to the cutting tool, the screw and nut being located along the spindle axis and their inner diameters are greater than the outer diameter of the spindle, and the length of the screw and the length of the nut are equal to or greater than the depth of the cut hole along with the length of the connecting element between the device and the pipeline.
