されている。FIGS. 7 and 8 show such a conventional end mill. The end mill 10 of FIG. 7 is provided with the tip seats 2 of rows A to D facing the rotational direction on the side surface of the tool body L. In the end mill 10 in which the tips 3 and 4 are mounted on 2, the nickless tip 3 is mounted on rows A and B of the end mill 10, and the nicked tips 4 are mounted on rows C and D.

効率が著しく低下するという問題があった。However, the above-mentioned conventional technique cannot avoid the following drawbacks. That is, in the case of the end mill shown in FIG. 7, if the tip mounting position is wrong, for example, if nicked tips 4 are attached to rows B and D and nickless tips 3 are attached to rows A and D, as shown in FIG. However, there is a problem that a part of the nick shape is transferred to the finished surface of the work W. Furthermore, if the chips 3 and 4 are replaced to correct this state, it takes time and labor, and work efficiency is significantly reduced. There was a problem of doing.
