The hexagonal shape may exhibit maximum bending moment that may be suitable for bearing a cutting load. Also, the hexagonal shape may provide better grip while mounting on the tool post (108). Further, the strengthening plate (204) may be fastened to the extension bar (202) by a welding. In an embodiment, the strengthening plate (204) may be quadrangular in shape. The strengthening plate (204) may provide more strength to the extension bar (202) and hence to the device (200). The hexagonal extension bar (202) and the quadrangular strengthening plate (204) together may be configured to have reduced vibration of the radial planning machine. The tool holding device (206) may comprises a hole (214) to hold a tool and a threaded hole (216) for a bolt. The bolt may be fastened to secure the tool in the tool holding device (206). The tool holding device (206) may be fastened to the extension bar (202) such that the tool mounted in the tool holding device (206) may perform machining. Further, the vertical members (208) along with the extension bar (202) may be fitted in a slot of the tool post (108). The vertical members (208) and the extension bar (202) may be secured on the tool post (108) by a plurality of bolts. The vertical members (208) may configured to be fastened perpendicularly to the extension bar (202). Also, the interior side of the strengthening plate (204) may configured to be fastened to one of the vertical members (208).
