Abstract: Improvements associated with the life of cutting tools used to machine M42 tool steel are discussed in this paper. To achieve this, experiments using a variety of tool coatings are conducted on quenched and tempered M42. The limitations of the study include the employment of a short-time tool wear method. The paper presents original information on the characteristics of dry machining M42 tool steels under finish machining conditions.
