Abstract
Provided is an insert that has good positioning precision and sufficient rigidity. Said insert is rod-shaped and has: a shank part; cutting blades formed on both sides of the shank part; and raised surfaces that are positioned between the cutting blades and the shank part and bulge such that parts farther away from the cutting blades are progressively closer to the outer surface of the shank part. In a side view, the rake face of the cutting blade on one side and the raised surface on the other side are disposed in the same direction with respect to the axis of rotation of the shank part.
Claims11
An insert having a rod-shape, and comprising:
- a shank part;
- a cutting edge formed respectively on both sides of the shank part;
- and
- a rising surface located between the cutting edge and the shank part that protrudes so as to approach the outer peripheral surface of the shank part as it moves away from the cutting edge,
- wherein a rake face of the cutting edge on one side and the rising surface on the other side are arranged in the same direction with respect to the rotational axis of the shank part when viewed from a side surface.
A cutting tool, wherein an insert is inserted into an insertion hole that is formed at a tip end of a holder, securing a rising surface in abutting contacting with the adjustment member provided with the holder, wherein the insert has a rod-shape, and comprises:
- a shank part,
- a cutting edge formed respectively on both sides of the shank part, and
- a rising surface located between the cutting edge and the shank part that protrudes so as to approach the outer peripheral surface of the shank part as it moves away from the cutting edge,
- wherein a rake face of the cutting edge on one side and the rising surface on the other side are arranged in the same direction with respect to the rotational axis of the shank part when viewed from a side surface.
