The paper presents the results ofstudies onthe topography of surgical borers flank after their operation. The studies were carried out on borers made of X39Cr13 martensitic steel, which was subject to heat and surface (plasma nitriding) treatment. Test drilling was performed in beef bones, which were fixed in a vice to ensure appropriate stability, a borer 6 mm in diameter and 160 mm long was used. The studies on the topography of flank comprised studies on roughness, which were carried out by means of a profilographometer designed for 2D and 3D studies on the surface by means of a contact method. The studies were carried out for borers of flank formed by successive drilling cycles
