Summary: | A cutting insert of the present invention comprises: a top surface; a bottom surface; side surfaces; a first cutting blade formed on a connecting part between the top surface and the side surfaces; and a second cutting blade formed on a connecting part between the bottom surface and the side surfaces. The first cutting blade comprises a first inner cutting blade and a first outer cutting blade connected with the first inner cutting blade. The side surfaces comprise main side surfaces and auxiliary side surfaces, and the main side surfaces comprise a first flank face connected with the first inner cutting blade and a second flank face connected with the first outer cutting blade. The extension line of the first and second flank faces make acute inner angles with the extension line of the top surface. The present invention aims to facilitate discharge of chips to improve cutting performance during a high feed milling process.
