[Problem] To accurately set the orientation of a linear cutting blade when mounting a cutting tool and to reduce the production cost of a holder, the cutting tool, and the like. [Solving Means] A machine tool includes a moving device (M1 to M3) that moves a rectangular plate-shaped cutting tool T1 provided with a linear cutting blade Th in a Y-direction of a Z-direction, the Y-direction, and a Z-direction, or in a combined direction of the Y-direction and the Z-direction, the Z-direction being parallel with the axis of a main spindle 7 for holding a workpiece W, the X-direction being perpendicular to the Z-direction and determining the amount of cutting of the workpiece W, the Y-direction being perpendicular to the Z-direction and the X-direction, and a holder 25 that holds the cutting tool T1 in a state in which the orientation of the linear cutting blade Th is inclined with respect to the Z-direction when seen from the X-direction. The holder 25 has a first reference surface 26a that is in contact with a first surface Ta parallel with a linear cutting blade Th, of the side surfaces of the cutting tool T1 and is parallel with the YZ-plane or a plane tangent to the peripheral surface of the workpiece W and a second reference surface 26b that is in contact with a second surface Tb intersecting the first surface Ta. The workpiece W is cut while moving the linear cutting blade Th in the Y-direction or the combined direction. |
