It's known that the durability of the cutting tool is influenced by the cutting parameters. In the recent years, scientists turn their research efforts to demonstrate that the microgeometry have an important role in determining the durability of the cutting tools. The processes studied most are milling and turning, but few researches have been done on the drilling operation. In this paper is presented the influence of 6.8 mm diameter drills with three values of the K-factor, but the same radius of the cutting edge and same macrogeometry. To obtain the desired microgeometry of the drills, two preparing technologies of the cutting edge were used. Drills were tested in two types of materials: X5CrNi18-10 (1.4301) and 42CrMo4 (1.7225). The main goal of this paper is to observe the influence of the microgeometry in the drilling process namely the durability and wear evolution.
