As a result, the control of the process of basing a roller bit in a chuck was experimentally tested and introduced into production by measuring the gap between the working surface of the restrictive ring and the calibrating surface of the cone in order to increase the accuracy of drill bit manufacturing. Bits with a diameter close to the lower limit value can be machined in a chuck with a restrictive ring of reduced diameter. Height differences of the cones are reduced by introducing into the production the method of group interchangeability of sections in height, measured in a direction parallel to the axis of the bit.
