摘要： A handy air tool has a grip including a cylindrical tool holding section and a valve housing fitted therein. Both tool holding section and valve housing are molded from plastic material. Air supplying and exhausting passages are formed at the time of molding the valve housing and a hole for receiving a control a valve mechanism without requiring finishing. A least portion of air supplying ducts can be formed between the tool holding section and the valve housing. The tool is provided in the tool holding section with a locking mechanism comprising a hook portion extending from the free end of an operating lever toward the grip, and restricting elements for holding the hook portion so as to close a control valve member when it is necessary to keep the tool in a non-operating state. When applied to a grinding belt type air tool, a latch mechanism is provided for selectively retaining a grinding belt in a loosened state and in a tightened state and for preventing the grinding belt supporting member from slipping off a tension bar.

摘要： A safety device for a pneumatic tool having a body and an operation lever and a valve stem lowered by the operation lever has an axially movable pivot shaft by which the operation lever is pivoted to one end of the main body of the pneumatic tool. A stop is formed on the pivot shaft so as to move between a resting position and an operating position together with the pivot shaft. A conical coil spring is provided to urge the operation lever upward by its torsional action and the stop as well as the pivot shaft toward the resting position of the stop by its compressive action. A receiving chamber is formed in the operation lever at a position where it coincides with the stop when the stop is moved to the operating position by the depressing of the pivot shaft. When, in this state, the operation lever is pushed downward to cause the stop to enter the receiving chamber, the valve stem is lowered and the operation of the pneumatic tool starts.

摘要： An annular hole cutter has a radially inner cutting tooth portion and a radially outer cutting tooth portion. Each of the inner and outer cutting tooth portions is formed with a flute for ejecting cut chips on the outer periphery of the cutter, and a cutting edge for radially outwardly pushing the cut chips. Therefore, the cut chips are smoothly ejected through the flute, and thus an annular hole is precisely cut at high speed.
