Abstract

PURPOSE:Inner and outer tip configuration is newly arranged. By doing so. perforation, finishing boring and edge machining can be done effectively. CONSTITUTION:An inner and outer tip; 10 and 20, is of same shape and phase difference of the two for the rotating direction is 150 deg.C -120 deg.C. A center side cutting blade 16 is formed by a side in which an acute angle 12 and an obtuse angle 13 of the inner tip is in one line common and an outer side cutting blade 26 is formed by a side in which an obtuse angle 23 and an acute angle 22 is in one line. The acute angle 22 for the outer tip 20 is located 0.1 - 0.5 mm ahead of axial direction than the front end of the obtuse angle 13 and is located most outer circumference of the tool in the diameter direction. And adjacent obtuse angle 23 is situated in the inner side to the direction of diameter and backward to the axial direction over the obtuse angle 13. Furthermore, second obtuse angle 25 of the outer tip is situated in the inner side to the direction of diameter and backward to the axial direction over the acute angle 22 and is located far from the center of rotation from the front end of the obtuse angle 13 of the inner tip 10.
