Abstract
A cutting insert for an indexable drill according to the present disclosure may be used for external cutting or internal cutting depending on a position and a direction in which the cutting insert is installed even though a single type of cutting insert is provided. In addition, the cutting insert for an indexable drill according to the present disclosure has a section of the internal cutting edge which is involved in a cutting process or a section of the internal cutting edge which is not involved in the cutting process, which are clearly distinguished from each other, and as a result, the cutting insert may be rotated and mounted, and reversed and mounted on a drill body, such that maximum eight corners may be used to perform a cutting process.
