According to the invention a cutting tool material can be made by mixing 25 - 75 % by volume of high speed steel powder with 75 - 25 % by volume of a hard material powder containing 30 - 70 % by volume of hard principles based upon carbides, nitrides, oxides and/or borides of Ti, Zr, Hf, V, Nb, Ta, Mo, Cr and/or W and a binder metal based upon Fe, Ni and/or Co. The material can be used in solid cutting tools as well as in compound tools comprising said cutting tool material in combination with high speed steel or tool steel. |
