Abstract
The indexable insert of the present invention has a cutting edge at the end of a stick-shaped portion projecting from a tool base. The base is shaped to ensure effective clamping, thereby avoiding chatter and backlash. A cutting edge and a rake face are provided at the end of the stick-shaped portion, which is also provided with a side relief face so that chips cut from the workpiece are smoothly carried away. The cutting edge extends sideways beyond the side relief face so that the insert can effectively cut the walls of small and deep holes.

An indexable insert attached to a holder for cutting processing, comprising:
- a plate-shaped base having a top surface and a bottom surface, the base having a first side surface approximately perpendicular to the top surface and the bottom surface and a second side surface approximately perpendicular to the top surface and the bottom surface and having its rear end crossing the first side surface at an acute-angle,
- a stick-shaped portion formed integrally with said base and having its one first side surface extending forward from the base such that there is no step from a side surface of the base, an axis of the stick-shaped portion being parallel to the first side surface of the base, a cutting edge and a rake face connecting therewith being provided at a front end of the stick-shaped portion, a part of said cutting edge projecting sideward from the stick-shaped portion, said one side surface of the stick-shaped portion constituting a side relief face.
