Abstract: A sintered cermet and a cutting tool are provided which have high toughness and high anti-chipping. The sintered cermet comprises a hard phase composed of one or more kinds selected from carbides, nitrides, and carbonitrides of one or more metals selected from metals belonging to Groups 4, 5, and 6 of the periodic table, each of which is composed mainly of Ti; and a binder phase composed mainly of Ni and Co. When the crystal lattice constant of the binder phase is measured by Pawley method, two kinds of binder phases having two kinds of crystal lattice constants B1 and B2 exist in the interior of the sintered cermet. Alternatively, two peaks belonging to the (220) plane of the hard phase, namely, a low-angle-side-peak and a high-angle-side peak are detected in the interior of the sintered cermet, and a modified part exists in the vicinity of the surface, in which three peaks belonging to the (220) plane of the hard phase, namely, the low-angle-side peak, an intermediate-position peak, and the high-angle-side peak are detected.
