FIELD: mining industry. SUBSTANCE: cutting tool for mining machines has at least one plate from hard alloy brazed to holder fitted with tail part and cutting edge. Plate has thickness hpl meeting following relation 
, where k is coefficient equal to 0.25-5.6; Epl is modulus of elasticity of material of plate, kg/sq.mm; Ehold is modulus of elasticity of material of holder, kg/sq.mm; σpl is temporary resistance to bending of material of plate, kg/sq.mm; σhold is temporary resistance to bending of material of holder, kg/sq.mm and length Lpl meeting following relation Lpl= k1•h0,3
pl
, where k1 is coefficient equal to 15.0-25.0. In this case holder has thickness hhold equal to hhold=(Lpl/2)•tgα in section corresponding to half-length of plate. Another version of cutting tool includes plate having variable thickness. EFFECT: decreased energy consumption for rock breaking and enhanced productivity of mining machine. 6 cl, 6 dwg
