摘要:
PURPOSE: A drilling tool is provide to keep the rotational motion of a drilling tool balanced by changing the peripheral effective area of a guide bevel in the circumferential circle of the cross section of the drilling tool. CONSTITUTION: A drilling tool comprises a supporting shaft and a cutting insert(3). The cutting insert comprises an asymmetry main blade(15). The asymmetry main blade comprises a guide blade(10) and a free blade(13). The guide blade comprises a support bevel(12) and a guide bevel(23). The guide bevel follows the support bevel. The guide bevel and the support bevels are formed in on side of the supporting shaft. The guide and the support bevels of the cutting insert are consecutively expended. In a drilling process, the bevels guide the drilling tool in an inner wall of the drilled hole.
