Abstract

An insert according to the present disclosure comprises upper and lower surfaces joined by peripheral side surfaces provided with a through-hole extending between the upper and lower surfaces, each of the upper and lower surfaces comprising two raised portions and a central notch. The two raised portions adjoin two opposing side peripheral side surfaces, and extend along the entire length of the two opposing side peripheral side surfaces, and the upper surface comprises concave or convex surfaces curved along the two opposing side peripheral side surfaces. The central notch is formed as a flat plane between the two raised portions. The inserts according to the present invention are ground such that there is less removed volume during grinding and thus raw material can be saved. In addition, the grinding burden is much reduced compared with conventional inserts, and the service life can be increased.
