Abstract

PURPOSE:To enable to carry out roughing and finishing simultaneously, by reducing chips into small pieces through provision of grooves having a width of less than 1.8mm. in its section in the edge of a throw away tool chip. CONSTITUTION:Grooves 4b having a width a of less than 1.8mm. in a direction perpendicular to the plane of article to be machined are formed at the edge 4a of chip 4 shaped in the form of a regular triangle, which is fixed to a throw away tool holder by chip holding means, and corners 4d are formed on the inside of these grooves 4b. The chip 4 is obtained by coating a highly durable ceramic material or the like on the surface of a sintered material (conforming to JISP30). With such an arrangement, chips produced at the edge 4a are carried along lands c and grooves 4b, bent appropriately and broken into small pieces gradually.
