The results received at research of influence electron beam treatment processings on tool life of a tungstenless hard alloy metal on the basis of TiC with a binding material an alloy Ni-Cr-Al and percentage of the components "basis-binding" 50 – 50% about are presented in the conditions of metal cutting. Influence electron beam treatment of a blanket of samples of the cutting tool insert on technological components of force of cutting when turning cut metal is experimentally revealed.
