Abstract

PURPOSE:To make two rhombic or rhomboidal throwaway tips in use capable of high accuracy boring and suitable both for drilling and end milling by considering the balance of cutting forces. CONSTITUTION:Two rhomboidal throwaway tips 10 and 20 are housed in two depressions 31 and 32 in the tip portion of a tool 30, and cutting scrap discharge pockets 33 and 34 are provided in portions in the vicinity of the faces 11 and 12 of the tips 10 and 20. When the tips 10 and 20 are used as drills, cutting is started with blade tips 13 and 22 brought in contact with a workpiece. No vibration is generated upon biting and well-balanced cutting force can be gained. The tips 10 and 20 have a sufficient usefulness as end mills also.
