There is provided a cutting tool having high wear resistance and fracture resistance by reducing the occurrence of thermal cracking on a cutting edge even during a cutting process of a heat-resistant alloy in which the cutting edge reaches high temperatures. The cutting tool is made from a cemented carbide that is composed mainly of a WC phase and contains 11.5-12.5% by mass of Co and 0.2-0.6% by mass of Cr in terms of Cr 3 C 2 . The WC phase has a mean particle size of 0.85-1.05 µm, an antimagnetic force (Hc) of 13.0-16.0 kA/m, and a Rockwell hardness (HRA) of 89.5-90.5.
