A module mountable to a shaft portion of a cutting tool including the shaft portion, the module comprising:
- a body having a cylindrical shape that allows insertion of the shaft portion, the body being mountable to the shaft portion so that an inner peripheral surface of the body covers a peripheral surface of the shaft portion,
- wherein the body includes a recessed portion formed in an outer peripheral surface of the body.
A module mountable to a shaft portion of a cutting tool including the shaft portion, the module comprising:
- a columnar body mountable to the shaft portion in an axial direction of the shaft portion,
- wherein the body includes
- a recessed portion formed in a peripheral surface of the body, and
- a sensor mounting portion that is provided near the recessed portion and to which a strain sensor is mountable.

A cutting tool comprising:
- a blade mounting portion;
- and
- a shaft portion connected to the blade mounting portion,
- wherein, in a cross section perpendicular to a central axis of the shaft portion, the shaft portion has a rod shape having a circular or a polygonal peripheral surface,
- wherein the shaft portion includes
- a first section that is a part along a direction of the central axis,
- a second section adjacent to one side of the first section in the direction of the central axis, and
