Deflector wedge is designed to provide the necessary deviation from the axis of the main wellbore of cutting and drilling tools during drilling of additional wellbore and subsequent running of the liner. Rejector wedge is a wedge, resistant to rotation during shearing in the open hole, orientable, non-retrievable wedge with radial perforation holes, providing communication of the main and sidetrack during well operation. The launching of the whipstock is carried out on a starter cutter, installed in the guide funnel of the hydraulic anchor.
