Abstract
Provided is a structure for improving accuracy in attaching a cutting tool to a body and making it possible to increase the number of blades while the cutting tool is mounted on the body. A cutting insertincludes: an upper surfacethat has a shape with a lengthwise direction LD and a widthwise direction SD; a lower surface that is located opposite to the upper surface; a peripheral side surfacethat is formed so as to connect the upper surfaceand the lower surface; cutting edgesandthat are respectively formed on an intersecting ridge line of the upper surfaceand the peripheral side surface, and on an intersecting ridge line of the lower surface and the peripheral side surface, and each have a curved ridge line that extends in a lengthwise direction thereof; and a through holethat penetrates from the upper surfaceto the lower surface. End surfacesandlocated in the lengthwise direction LD of the upper surfaceand the lower surface, of the peripheral side surface, are respectively inclined with respect to the upper surfaceand the lower surface, and are parallel to each other. A reference surfacethat is located opposite to the cutting edgesand, of the peripheral side surface, is a flat surface that is orthogonal to the upper surfaceand the lower surface.
