Abstract
A cylindrical cutting tool for processing splines formed on an outer circumference of a shaft member to extend in an axial direction includes blade portions which are formed in a spline shape on an inner circumference. The blade portions include: a first blade portion which is formed in a terminal end portion in a first direction along the axial direction and which is directed substantially toward the first direction; and a second blade portion which is formed in a terminal end portion in a second direction along the axial direction and opposite to the first direction and which is directed substantially toward the second direction.
