Abstract

This article presents a research study on advanced special drills designed to improve the efficiency and quality of hole drilling processes in structural metals under the operating conditions of JSC “OKMK”. Drilling is one of the most critical machining operations in mechanical engineering, as it directly affects dimensional accuracy, surface quality, and the structural reliability of manufactured components. Improving drilling technology requires an in-depth analysis of tool geometry, cutting parameters, and material properties. The study analyze various types of advances drills, their geometric characteristics, cutting speed, feed rate, and cooling conditions. Special attention is paid to the influence of drill design on chip formation, heat generation, and hole quality. High-quality holes significantly affect the strength of joints, assembly accuracy, and the overall service life of machine parts. The article also evaluates the effectiveness of modern drilling technologies and provides recommendations for selecting optimal drilling tools and technological parameters to increase productivity and reduce tool wear under industrial conditions.
