The theoretical analysis of regularities of formation errors machining holes with the unevenness shoot allowance and education elastic movements in the technological system machine - tool - a tool - detail (MTTD). From the literature it is known, that increase the accuracy holes can decrease the energy intensity of treatment, a decrease in supply and an increase in the stiffness of elements of technological systems MTTD. The resulting solution opens up new directions for the intensification of the processing hole as dimensional and unmeasured instruments. It refers to the processes, reaming, reaming, boring, grinding holes. Therefore, in this paper on the basis of that decision justified conditions intensify the process of eliminating errors in the processing of the holes. It is shown that when drilling holes through participation in two opposed cutting blades increases the diameter of the drill hole to be treated by the amount of elastic displacement. With the emergence of boring holes in the process system elastic displacement does not exceed the diameter of the hole of the nominal value. This determines the fundamental difference between the conditions for the formation of error handling when drilling and boring holes. On the basis of dependency identify ways to improve the machining accuracy of holes, the main of which is to increase the number of blades multiple tip tools (core drills and reamers) involved in the removal of material
