Abstract

PURPOSE: To simplify cutting process for hard material by dividing the cutting edge part within center angles of 180° into multiple cutting edges with radii which increase one after another in the rotational direction and distributing the mass of one cut to these edges neary in proportion to the differences between the radii of these cutting edges.
CONSTITUTION: A cutting edge part 4 within center angles of 180° on a circumferential surface is divided into multiple cutting edges 7, 7', 7" in parallel to the axis. Larger radii are given to the cutting radii of these cutting edges 7, 7', 7" one after another in the rotational direction of the bit 1. Moreover, each of these masses of cut is distributed to them nearly in proportion to the differences between the radii of these cutting edges. A guide part 5 concentric with the cutting edge part 4 is equipped at center angles of 180°W90° on the circumferential surface symmetrical with the above cutting edge part 4 and comparatively hard materials are cut.
