Abstract This article presents the research results on influence of heat treatment chromium steel, used in production drill bits, their mechanical properties and operational safety. The analyses revealed that steel manufacturing studied bit underwent hardening tempering processes, which affected its structure hardness. presence tempered martensite manganese sulfides was observed, which, although not having a destructive impact steel’s properties, may limit formation undesirable iron sulfides. Additionally, layer with reduced hardness identified working surface bit, suggesting possibility tool overheating during operation. During tool’s use, complex stresses, such as torsional, compressive, bending accumulate areas prone to damage, especially at interface between tooth shank. emphasizes importance proper usage, including adjusting pressure drilling angle maintaining optimal conditions ensure safety durability. findings aim enhance workplace improve performance cutting tools materials engineering.
