<p>Provided are a cutting insert suitable for pocket machining of metal molds and the like, and an indexable cutting tool that uses the cutting insert. The cutting insert (10) is provided with: a rake face (14); a flank face (15); and a major cutting edge (11) that is formed on the intersecting ridge of the rake face (14) and the flank face (15), and that extends in the direction that intersects with the cutting direction of the rotary cutting tool. At least one partitioning section (12) that is not involved in cutting is provided in the middle of said major cutting edge (11) in a direction along the major cutting edge (11). The major cutting edge (11) is composed of two first cutting edges (11a) and second cutting edges (11b) separated by the partitioning section (12), and is configured in such a manner that, when the cutting insert is attached to the tool body (1) of the cutting tool, the cutting angles (?1, ?2) between the first cutting edge (11a) and the second cutting edge (11b) falls in a range of 5° and 20°.</p> |
