The process of location error the bit in the chuck was verified experimentally and put into production by measuring the gap between the working surface of the limiting ring and the calibrating surface of the cutter to improve the accuracy of the bit production. Bits having a diameter close to the lower limit value can be processed in a cartridge with a restrictive ring of reduced diameter. The height of cutters is reduced as a result of introduction into production of the method of group interchangeability of sections in height, measured in a direction parallel to the axis of the bit.
