Inserts and cutting tools |
| abstract |
The insert of the present disclosure comprises a silicon nitride sintered body containing β-Si 3 N 4 as a main component. The range of 0.5 mm from the surface of the silicon nitride sintered body is defined as the first region. The first region has an oxygen content of less than 0.8% by mass. The first region has ReMgSi 2 O 5 N (Re is at least one of Yb and Y). The cutting tool of the present disclosure has a holder extending from the first end toward the second end and having a pocket on the first end side, and the above-mentioned insert located in the pocket.
