A comparative analysis of the stressed state of symmetric and asymmetric teeth of a centrifugal-volumetric-reinforced helical cutting structure is carried out. A dependence of the stress distribution with respect to the width of the working surface is established, and the mode of deformation of two adjacent teeth of the cutting structure simultaneously in contact with the well bottom is studied.
