Provided is a cutting tool with a replaceable blade edge having a configuration whereby the rotational moment acting on a cutting insert that is clamped to the insert attachment surface of a body can be supported in a stable manner. This cutting tool has: cutting inserts (10); a body (20) equipped with insert attachment parts (21) to which the cutting inserts (10) are mounted in a removable manner; and receiving mechanisms that receive the rotational moment acting on the respective cutting inserts (10) so as to cause the cutting inserts (10) mounted on the insert attachment parts (21) to rotate on a base surface (21A). The receiving mechanisms include first engaging parts (14), which are formed on the lower face of the cutting inserts (10), and second engaging parts (25), which are formed on the base surface (21A) of the insert attachment parts (21). The second engaging parts (25) are formed so as to receive the rotational moment by engaging a specific portion (15) of the surfaces demarcating the first engaging parts (14). |
