Sintered cermet materials far tools such as cutting tools, which are excellent in heat resistance, wear resistance and fracture resistance, are inexpensive, and have long life time, and a method for producing such sintered cermet materials. The sintered cermet materials for tools are composed of sintered bodies which are obtained by preparing a mixed powder containing powders of TiCN, Si3N4, Al2O3, CrxN (x=1-2.7 and ZrN, at least one powder of W and WC, and at least one kind of metal powder selected from the group consisting of Co, Ni, Ta and Mo, and sintering the mixed powder .
