<P>PROBLEM TO BE SOLVED: To provide a fluid removal tool capable of removing fluid out of a container without leaking the fluid into a working space. <P>SOLUTION: The fluid removal tool 100 opens a hole 16 in a tank 13 which contains PCB oil and removes the PCB oil from the tank 13 through the hole 16. The fluid removal tool 100 includes a drill blade 51, a tool body 20, and a drill blade coming-off preventing metal fitting 56. The drill blade includes a top end portion 52 and a shank portion 54. The tool body 20 movably supports the drill blade 51 in an axial direction. A fluid penetration space 21 in which the front end portion 52 is disposed and which opens on a line in the axial direction of the drill blade 51, and a through-hole 28 which is communicated with the fluid penetration space 21 and in which the shank portion 54 is inserted are formed in the tool body 20. The drill blade coming-off preventing metal fitting 56 locks the drill blade 51 to the tool body 20, and regulates movement of the drill blade 51 in a reversal direction. <P>COPYRIGHT: (C)2009,JPO&INPIT |
