Durability of cutting tools represent a large spectral index on the basis of which is characterized by functional work. Every manufacturer of cutting tools before the actual production of these tools during the development make a tests and prescribing them characteristics on which is possible then to predict their behaviour in the actual production process. Durability of cutting tools is often indicated for one tested material of marketing aspect, which is machined and effort of user is to achieve this variable for other machined materials and then is happened problem in the production. The problem is very short lifetime of cutting tool in machining process, where the effect is impossibility to optimize the machining process. The results of this action are excesses time caused by exchanged of cutting plate and then it is make a low production of machining industry by setting of machines, and then the factory has an economical loses. Paper notes that significant differences optimal and feasible achievable durability of the cutting tool in the machining process carbon steel. As the impact on the results of this research is not only technical but also economic and particularly for small and medium manufacturing enterprises, it is examining this issue very important and timely.
