Drilling wells to produce drinking water and hydrocarbon raw materials requires more efficient means and methods. Couplings and nipples of drilling connections are made by turning. This process depends on the geometrical parameters of the turning tools. Almost all modern manufacturers of cutters use tools with an inclination angle of the cutting edge to ensure the stability of the cutter. The value of this angle is equal to the helical lead angle and therefore depends on the pitch and diameter of the thread. For small-sized drill connections, the helical lead angle can exceed 3.5°, which leads to a change in the thread profile since the threaded screw becomes in shape not the usual Archimedean screw but a convoluted helicoid. So, from this point of view, the study of the accuracy of the thread profile is theoretically justified because it is based on a correct calculation. The smallest NC10 drill pipes connector is chosen for this work because its helical angle reaches 3.75°. The application of the calculation algorithm developed by the authors showed that the deviation from the nominal half-profile angle of 30° ± 0.75° reaches 0.24°, which is 30% of the tolerance and indicates the importance of taking into account this technological component of the turning process to ensure the accuracy of the NC10 drill bit.
