Lead free cutting steel has been widely used because it has good machinability under various cutting conditions. However, the use of lead free-cutting steel decreases because lead has been bad for the environment. Therefore lead-free free-cutting steel has been developed. In addition, the dull edge tools take the place of the sharp edge tools. In this paper, the influence of cutting edge roundness and tool material are examined for luster on surface of free-cutting steel. As the result, it has been clarified that the surface of lead-free free-cutting steel is less than that of S45C-steel, and that the dull edge tool makes the surface lustrous.
