AB This article is aimed at the comparison of coated carbide cutting tool inserts used in machining of cylinder liners made of grey cast iron. The comparison has been realized through the tool life tests. The measurement has been carried out at three cutting speeds at constant cutting conditions. From the obtained values, the regression coefficients have been evaluated. Subsequently, extrapolation has been carried out by means of the regression line for the cutting speed in the range of 250 - 500 m/min, and for this the extended cutting speed range the interval reliability has been evaluated. In the experiments, it has been found, at the given conditions, it is not possible to recommend these cutting tool inserts for high speed machining.
