摘要： An assembly-type cutter (10) includes a shank (20) and a cutter head (30). The shank (20) has a hole (201) at one end. The hole (201) has a receiving portion (21), which includes an internal thread (212) and can be treated thermally for increased rigidity. The cutter head (30) has a cutting portion (32) and a connecting portion (31) at opposite ends respectively. The connecting portion (31) includes a threaded member (312) and can also be treated thermally for increased rigidity. The cutter head (30) and the shank (20) are threadedly connectable via the connecting portion (31) and the receiving portion (21). The threaded member (312) includes a body portion (3121), whose diameter is defined as a root diameter (Di), and an external thread (3122) on the body portion (3121). The body portion (3121) is slightly tapered such that a locus of the root diameter (Di) is inclined.

摘要： [Problem]
While a configuration is equivalent to a configuration where a cutting edge portion of a tool includes a core, cutting ability is provided to a part near a center of a tool end surface to secure an ability of handling a thrust process and a helical process that allow a cutting at the center part.
[Solution]
A cutting edge portion 1 includes gashes 8 and 9 between cutting edges 1A and 1A adjacent in a rotation direction. Center cut edges 10a to 10f are formed at parts of end cutting edges 2a to 2f constituting the cutting edges 1A close to a rotation axis O so as to face the rotation axis O. Center grooves 10A to 10F are formed on rear sides of the center cut edges 10a to 10f and the end cutting edges 2a to 2f in the rotation direction continuous with a radial direction. The center grooves 10A to 10F are continuous with positions where end cutting edge second surfaces 4a to 4f face the rotation axis O. Alternatively, the center grooves 10A to 10F are continuous with positions where the end cutting edge second surfaces 4a to 4f approach the rotation axis O. The end cutting edge second surfaces 4a to 4f are laid between the center cut edges 10a to 10f and the end cutting edges 2a to 2f. The center grooves 10A to 10F are formed between the end cutting edge second surfaces 4a to 4f and the center cut edges 10a to 10f positioned on a rear side of the end cutting edge second surfaces 4a to 4f in the rotation direction. The center grooves 10A to 10F pass on the rotation axis O. The center grooves 10A to 10F double as rake faces of the respective center cut edges 10a to 10f. The center grooves 10A to 10F are continuous with the gashes 8.摘要翻译： [问题]虽然构造等同于工具的切削刃部分包括型芯的构造，但是为了确保处理推进过程的能力和螺旋状 允许在中心部分切割的过程。 切削刃部1在旋转方向上相邻的切削刃1A，1A之间具有间隙8,9。 中心切削刃10a至10f形成在构成切削刃1A的靠近旋转轴线O的端部切削刃2a至2f的部分处以面对旋转轴线O.中心凹槽10A至10F形成在中心的后侧 切削刃10a至10f和端部切削刃2a至2f在旋转方向上与径向连续。 中心槽10A至10F与端部切削刃第二表面4a至4f面向旋转轴线O的位置相连续。或者，中心槽10A至10F与端部切削刃第二表面4a至4f接近旋转的位置 轴端O.切削刃第二表面4a至4f铺设在中心切削刃10a至10f和端部切削刃2a至2f之间。 中央槽10A至10F形成在端部切削刃第二表面4a至4f与位于端部切削刃第二表面4a至4f的沿旋转方向的后侧上的中心切割刃10a至10f之间。 中心槽10A至10F在旋转轴线O上通过。中心槽10A至10F与中心切割边缘10a至10f的前刀面一样。 中央槽10A〜10F与齿8连续。
