摘要

The present invention relates to a cutting insert and an indexable drill. The cutting insert and the indexable drill, according to the present invention, are implemented such that the cutting insert is initially inserted into the indexable drill with ease when the cutting insert is fitted into the indexable drill and the combining force between the indexable drill and the cutting insert is strong when fitting is completed. In addition, the cutting insert, according to the present invention, has excellent hardness, when compared to conventional cutting inserts that perform identical/similar cutting processes, since a low hardness portion is provided as a thick portion.
