ABSTRACT:
This insert type cutting instrument includes: an insert formed as a flat polygonal plate, and an instrument main body having a first through-hole and a second through-hole are formed in the insert. The insert is mounted on the seat so that the center of the first screw hole is located closer to the axis than the center of the first through-hole and is located closer to a base end of the body than the center of the first through-hole, and the center of the second screw hole is located closer to the axis than the center of a second through-hole and is located closer to the base end of the body than the center of the second through-hole. Each of the first screw hole and the second screw hole is formed to be orthogonal to an attachment surface of the insert seat.
