This paper presents some of results of experiments carried out to determine the relationship between cutting temperature and durability of cutting tools. Three kinds of carbon steel were turned by high-speed steel tools of same kind and shape under various cutting conditions, and the cutting temperature was measured by the tool-work thermo-couple method. Durability tests of tools were performed under the same depth of cut and feed per revolution and various cutting speeds. Some important conclusions obtained dare as follows : (1) The cutting temperature θ is exprssed as θ=k T^β v^α, T mean thickness of chip, v cutting speed, k, α & β constants of work material. This relation is a characteristics of work material. (2) The tool life M is expressed as M=k_m T^γ θ^<-m>, where k_m, γ & m are constants of tool. This relation is a characteristics of cutting tool.
