Abstract

Provided is a cutting-edge replaceable cutting tool having a configuration capable of stably supporting a rotational moment acting on a cutting insert clamped on an insert mounting face of a body. It includes a cutting insert, a body including an insert mounting portion for removably mounting the cutting insert and a reception mechanism to receive the rotational moment acting on the cutting insert so as to rotate the cutting insert mounted on the insert mounting portion on a base surface, the mechanism including a first engagement portion formed on a lower surface of the cutting insert and a second engagement portion formed on the base surface of the insert mounting portion which is formed to engage with a specific portion of a surface defining the first engagement portion to receive the rotational moment.

Dependent claims

A cutting-edge replaceable cutting tool comprising:

a plate-like cutting insert comprising upper and lower opposite surfaces and a side surface extending between the upper and lower surfaces;
a body including an insert mounting portion for removably mounting the cutting insert, the insert mounting portion having a base surface for supporting the lower surface of the cutting insert and a sidewall surface for supporting the side surface of the cutting insert;
and
a reception mechanism configured to receive a rotational moment, the rotational moment acting on the cutting insert so as to rotate the cutting insert mounted on the insert mounting portion on the base surface,
wherein the reception mechanism includes a first engagement portion formed on the lower surface of the cutting insert and a second engagement portion formed on the base surface of the insert mounting portion, and
wherein the second engagement portion is formed to engage with a specific portion, of a surface defining the first engagement portion, to receive the rotational moment.
