The paper reports the consideration of problems regarding obtaining qualitative blanks for manufacturing hard-alloy tools. There are analyzed potentialities for manufacturing a cutting part made of hard-alloy bar stocks, profile blanks with HRA88 rated hardness and with the use of flexible blanks. The impropriety of common methods of designing screw teeth with an axial-radial varied pitch is shown and a method of purposeful designing with a new version of initial information is shown. The potentialities of 3D technological modeling for the assessment of the tool designed are shown.
