PROBLEM TO BE SOLVED: To carry out highly efficient machining by enhancing supporting rigidity of a tool when performing shaving, slotting and broaching by using a machine tool, and to reduce damage of a spindle of the machine tool. SOLUTION: This cutting device 11 is provided with a spindle head 23 of the machine tool, the spindle 25 rotatably supported by the spindle head 23 around a rotation axis 27, and a cutting attachment 15 mounted on the spindle 25 to support a cutting tool 43. The cutting tool 43 is reciprocatively moved in the rotation axis 27 direction in relation to a workpiece W. In the one stroke, the workpiece W is cut by the cutting tool 43. In the cutting device 11, an end face of the cutting attachment 15 in the rotation axis 27 direction is arranged to abut on an end face of the spindle head 23. A part or all of force of the rotation axis 27 direction applied to the cutting tool 43 at the time of cutting is received by the end face of the spindle head 23 via the cutting attachment 15.
