Indexable drill insert for machine tools for metalworking

Indexable drill for machine tools for metalworking

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.

Cutting insert for indexable drill

The present disclosure relates to a cutting insert and an indexable drill. The cutting insert and the indexable drill according to the present disclosure are configured such that when the cutting insert is mounted on the indexable drill, the cutting insert is easily inserted into the indexable drill at the initial time, and strong coupling force is implemented between the indexable drill and the cutting insert at a point of time at which the cutting insert is completely mounted. In addition, the cutting insert, according to the present disclosure, has excellent rigidity, when compared to cutting inserts in the related art that perform identical/similar cutting processing, since a portion, which is weak in rigidity, is provided as a thick portion.
