Abstract:
To provide a rolling tool holder which can form a thread in a workpiece with high precision.SOLUTION: A holder 100 includes: a holding member 110 which holds a rolling tool 1; and a restriction member 120 disposed at the holding member 110. The restriction member 120 is formed in a manner that the restriction member 120 can contact with a head part 22 of a shaft support member 20 from the radial outer side of a pedestal 10, and thus the shaft support member 20 is inhibited from being deflected by a pressure applied during rolling. As a result, a space among dices 30 is inhibited from expanding and a thread of a workpiece can be formed with high precision.SELECTED DRAWING: Figure 1
