The report presents the study of the performance of high-speed tools steel (HS) wear when milling various wood species. The tests were done using wood samples prepared of oak, birch and pine grown in Lithuania. The samples were milled along the grain in the wood cutting stand. The wood samples were milled at two different cutting and two different feeding speeds. The main characteristic to describe the wear of milling tool were chosen to be the cutting edge radius, were determined by the method of lead prints, using the optical microscope and digital microscopy camera. The average values of the cutting edge radius were determined in the fixed intervals of cutting path. The measurements were done five times in each interval of path. The received results allowed deriving the average values.
