Abstract
The work of the carbide peripheral armament of roller cones is analyzed by graphoanalytical method. It is shown that the task of ensuring the effective operation of this armature remains relevant. The main factors reducing the efficiency are the formation of slats on the peripheral and pre-peripheral parts of the bottom hole and spiral protrusions on the borehole wall. A solution to this problem is proposed and substantiated by means of pairwise placement of teeth in double-row peripheral crowns in combination with additional undercutting teeth on the periphery of the cones.
