Zusammenfassung:	FIELD: machine engineering, possibly manufacture of different types of cutters, milling cutters, drills, screw taps and so on. ^ SUBSTANCE: tool is made of quick cutting steel P18 containing ferrite a-Fe alloyed with chrome and tungsten and carbide Fe3W3C of quick cutting steel. Mean size of blocks cc-Fe is no more than 42 nm; of Fe3 W3C blocks - no more than 32 nm. Micro-deformations of crystal lattice oc-Fe are no more than 4.7 x10-3 and micro-deformations of crystal lattice of Fe3W3C are no more than 6.5 X10-4. ^ EFFECT: increased strength of steel, increased useful life period of tool. ^ 1 tbl, 1 ex
