This paper deals with the lubricating action of nonmetallic inclusions in metal cutting. The purpose of this study is to find the most effective inclusions for metal cutting, and to develop free machining sintered metals including nonmetallic materials. The most effective additives are glass, boron nitride, and talc. By the addition of 3 percent glass to the iron, tool life could be increased 60 times.
