Abstract
A cutting tool may include a main body extended from a first end to a second end. The main body may be rotatable around a rotation axis. The main body may include a first cutting edge, a second cutting edge, a first flute and a second flute. The first flute may be extended from the first cutting edge toward the second end. The second flute may be extended from the second cutting edge toward the second end. The first flute may include a first hole located in the main body. The second flute may include a second hole located in the main body. The first hole may have a circular shape and the second hole may have a long narrow shape in a circumferential direction of the rotation axis in a cross section orthogonal to the rotation axis.
