In a cutting tool according to an aspect of the present invention, a first cutter and a second cutter are attached to a holder. A projection amount of the first cutter that projects substantially in the horizontal direction from the holder is greater than a projection amount of the second cutter that projects substantially in the horizontal direction from the holder. A cutting resistance of the first cutter to an object to be cut is smaller than a cutting resistance of the second cutter to the object to be cut so that a rotation axis of the cutting tool is disposed at substantially the same position as a center-of-gravity position of a horizontal section of the holder during cutting of the object to be cut while rotating the holder. |
