PURPOSE: A tool for separating and combining a nut is provided to conveniently eliminate or combine a reamer bolt by using hydraulic pressure. CONSTITUTION: A reamer bolt(2) to be released is decided for matching an uneven portion(13a) of a connect unit(13) in a combining tool(10) to an uneven portion of a nut(1) combined to the reamer bolt. Herein, the uneven portion of the nut forma a specific pitch. By lifting the combining tool, matched state of the uneven portions is released. By rotating the combining tool, the nut is rotated. A portion(15) formed at an upper end of the combining tool is stored in a socket(20). Then, the socket is rotated for identifying through holes(27) of the socket with a through hole(17) of the portion at the upper end. A fixing pin(29) is located for penetrating the through holes for fixing the socket with the upper portion. A hydraulic pressure pack(30) having a groove identified with a protrusion unit(24) at the socket surrounds the protrusion unit. By operating an oil pump(35), the pack is rotated by the oil supplied from the oil pump.
