PURPOSE: A device for removing a burr inside the diameter of a hole is provided to be directly inserted into a hole and actively operate a cutting tip of a tool in the area where a burr is formed and to operate even in multiple areas at a time where a burr needs to be removed. CONSTITUTION: A device for removing a burr inside the diameter of a hole includes a workbench body (500) with a predetermined length in order to be inserted into a hole to a certain depth where a burr needs to be removed. An electric motor for rotational driving, which generates rotational power, is installed on one side of the rear part of the work bench. A rotation transmission device is inserted in the workbench body. A bevel wheel gear (800) is formed in the center of the axis of the top end of the rotation transmission device. A unit (A) or more for operating multiple burr removal blades which are divided respectively is/are arranged to the outside from the center of the bevel wheel gear. |
