Abstract
A cutting tool includes a grip part and a cutting part. In the grip part and the cutting part, a channel for guiding fluid supplied from the outside to an outflow port is formed. The channel includes: a first channel extending in parallel to a rotational center axis and linearly from an end part of the grip part on an opposite side to the cutting part; and a second channel extending linearly from the first channel toward a cutting edge of a cutting insert. The first channel is formed such that a center axis thereof is decentered so as not to match the rotational center axis.
