CONSTITUTION: A core-drill separating tool(100) comprises a striking holder(20), a fixed striking unit(30), a coupling nut(40), and a spring washer(50). A fixed shaft comprises a coupling shaft, and first to third coupling units. The first coupling unit is formed on one side of the coupling shaft and the second and third coupling units are formed on the other side of the coupling shaft. The first coupling unit is coupled to the mounting unit(1) of a core drill(5). The striking holder is slidably coupled to the outer surface of the coupling shaft. |
