Abstract

This bachelor thesis focuses on the selection of the optimum monolithic carbide drill bit from the ANAJ range. In the introduction, the structure and function of monolithic carbide drill bits are described in general terms, as well as the different types of wear. This is followed by an experiment in which the drills are tested and compared on the basis of two criteria. The first criterion is the cutting forces during machining, i.e. torque and feed force. The second criterion is the wear on the cutting edge of the tool.
