Purpose: It has been demonstrated in the paper structure and properties of high speed-steel HS6-5-2 type manufactured by different method of powder metallurgy. Design/methodology/approach: Light microscope, SEM, image analysis, hardness tests, density examination, transverse rupture strength tests, analysis of chemical composition by LECO apparatus. Findings: Basing on the investigations of the HS6-5-2 type high-speed steels reinforced with ceramics particles fabricated with Powder Metallurgy it was found of that density of sintered samples depend on reinforced particles, temperatures and atmosphere of sintering. Increasing of sintering temperature increase the density of sintering samples. Moreover the sintering under N2-10%H2 atmosphere produce samples with higher quality than using argon atmosphere and prevent of surface oxidation during sintering. Practical implications: The modern methods of powder metallurgy gives the possibility to manufacturing tool materials on the basis of high speed-steel which characterised very good properties with their final shape. Originality/value: In the paper the manufacturing by modern PM methods of tool materials on basis of high speed-steel manufactured carried out in order to improve the structure and properties of tool materials and to produce tools with their final shape.
