PROBLEM TO BE SOLVED: To solve the problems of causing risk of having influence up to a shaped surface except for a burr, and of easily breaking since an overload is applied to a tool of including a wire rod, by an expansion width of the metallic wire rod, due to being actually smashed up rather than shaving the burr by expanding the metallic wire rod by centrifugal force, though this kind of thing is to remove the burr by contacting with the burr by expanding the tip in a substantially conical shape by the centrifugal force when rotating, by being constituted of a bundle of a plurality of metallic wire rods, though proposing a deburring tool of a core as indicated in Patent Literature 1.SOLUTION: In a rod-like member connected to a driving part provided in a driving device, the problem is solved by cutting a burr by a recessed groove, by forming at least one recessed groove in the axial direction of the rod-like member on an outer peripheral surface in the rod-like member.SELECTED DRAWING: Figure 2 |
