To reduce a equipment cost of a device performing center hole work of a shaft-shaped object.

A shaft-shaped object work device is provided with a work head 14 and a chuck 16, so as to be formed such that a rotary shaft lien of a turret 40 of the work head 14 and a rotary shaft line of the chuck 16 are placed at a right angle to each other. In the case of working a center hole in a shaft 100, in a condition holding the shaft 100 to the chuck 16, one end face 102 of the shaft 100 is cut by an end face cutting tool 46 to form an end face 106. Thereafter, the turret 40 is rotated, a center hole drill 48 is positioned in a work position, and a center hole 108 is formed in the end face 106. When work in a side of the end face 102 is ended, the chuck 16 is rotated by 180 degree, an end face 104 is opposed to the work head 14, and end face cutting work and center hole work are performed, similar to the case of the end faced 102.
