Turning with environment-friendly cooling method using water evaporation for the earth was investigated and reported by previous authors. In the turning using water evaporation, the tool life was twice of that of the dry cutting. Surface roughness of workpiece using this cooling was the same to that of dry cutting. Cylindricity of workpiece using this cooling was one third of that of the dry cutting. Other cuttings with environment-friendly cooling using water evaporation were investigated in this report. The cutting process are drilling, milling using face mill and cutting using circular saw. In drilling, water was supplied to the workpiece through a tool holder and a hole on the drill. In same case of milling using face mill, water was supplied on a few tips with carbon cloth through a tool holder and a holder of face mill. And in case of cutting using circular saw, water was directly supplied on the circular saw in the cover during the air cut. In this experiment, temperature changes and tool lives of each tool were measured. It is concluded from the results that environment-friendly cooling using water evaporation was very effective for improving tool life of three cases.
