The industrial relevance of bore holes with small diameters and high length-to-diameter ratios rises with the growing requirements on parts and the tendency of components for downsizing. Examples for components requiring deep holes with small diameters exist in the automotive industry; for the production of injectors for fuel injection as well as for medical and biomedical parts. Based on growing functional requirements, for example with the increase in injection pressure to improve the efficiency of the combustion process in diesel engines, the requirements on the surface integrity of bore holes also increase. To meet these requirements, an adaption of the deep hole drilling process is necessary. In this paper the influence of tool geometry, coating and cutting data on the bore hole quality and tool wear will be presented.
