Abstract

A device for cutting tubes in a well includes a body with radial channels and slots for placement of hinged by means of axles cutter holders with armored cutters held in initial position with spring holders, a piston with a bore-seat provided in the upper end surface for placement of a ball-valve, with longitudinal central circulation opening and cone arranged in the lower section of the piston for interaction with respective surface of the cutter holders, a spring for support and rotation of the piston to initial position, circular groove provided in the upper part of the body with installation of thrust ring, a radial opening provided in the middle section of the body for installation of the holding pin, this by means of a longitudinal groove provided at the outer surface of the piston holds the piston against axial turn, bushing, spring and holding ring installed in the lower section of the body, with possibility of axial displacement, with angular reborings provided at the outer surface of the body for fixation of angle holders. The radial circulation channels in the lower section of the piston are provided in front of the cutters as longitudinal slots, and the lower section of the bushing is arranged as a conical elongation of the body, and at its outer conical surface cutters with super-hard teeth are soldered in.
