摘要： A floatable hand tool includes a shank having an inner wall formed with an axially extending through hole, and a tool tip mounted on an end of the shank and having an end portion provided with a protruding connecting rod inserted into the through hole of the shank so that the through hole of the shank forms a closed chamber. Thus, the floatable hand tool floats on the water level by the floating force produced by the closed chamber the through hole of the shank. In addition, the floatable hand tool floats on the water level, thereby preventing the floatable hand tool from being missed when falling into the water, and thereby facilitating a user operating the floatable hand tool in the water.

摘要： An apparatus is disclosed for making aligned inclined holes in upper and lower work piece. The apparatus includes a set of drill bits and an alignment element. Each of the drill bits can be driven into the upper and lower work pieces to make the inclined holes. The alignment element includes a horizontal plate, a vertical plate extended from the horizontal plate and a tube extended from a corner formed between the horizontal and vertical plates. The horizontal plate is used for contact with the upper work piece. The vertical plate is used for contact with the lower work piece. The tube includes a tunnel for receiving a selected one of the drill bits, a space for receiving debris produced because of the drilling and an aperture through which the selected drill bit is inserted into the space from the tunnel.
