A pneumatic tool structure including a main body integrally having an elbow. A pneumatic motor, a switch unit and an intake unit are disposed in the main body. A driving unit is disposed in the elbow. The elbow has a top section formed with an opening corresponding to the main body. The pneumatic motor is placed into the main body from upper side through the opening. A cover is disposed on the elbow for closing/opening the opening.

A housing for a pneumatic tool includes a head portion, a middle portion, and a handle portion. A sleeve is disposed over the middle portion of a pneumatic tool with a rear portion of the sleeve spaced from the outer surface of the housing. A grip made of pliant material, preferably rubber or a synthetic rubber compound encloses the handle portion. The grip includes a front lip, and a rear flange. Once fully inserted on the handle, the sleeve and the external surface of the housing cooperate to retain the front lip therebetween, preventing the front lip from peeling off the handle portion. An adaptor engages an air inlet at a distal end of the handle portion. The adaptor can include a washer engageable with the air inlet for limiting the depth of insertion of the adaptor in the air inlet and for inhibiting rearward movement of the grip.

A pneumatic tool is provided having a housing with an exhaust passageway and a handle. The handle has an inlet that receives the housing, an outlet having at least one exhaust port, and an interior surface that defines an exhaust chamber. The exhaust passageway, exhaust chamber, and the at least one exhaust port are sequentially in fluid communication when the housing is inserted into the handle. A seal disposed between the interior surface of the handle and the housing, the seal being located between the exhaust chamber and the inlet. Also provided is a handle substrate with an inlet that receives the housing and an interior surface that defines an exhaust chamber. The exhaust chamber is in fluid communication with the exhaust passageway when the housing is inserted into the handle. An endcap is removably attached to the handle and has an outlet with at least one exhaust port in fluid communication with the exhaust chamber. A seal is disposed at an interface between the handle and the endcap.

A fastener driving tool includes a housing enclosing a fastener driving portion and a handle connected to the fastener driving portion. A pair of clamshells is configured to form an ergonomic grip over the handle and also forming a fastener magazine, such that the ergonomic grip and the magazine are integral in each clamshell. The clamshells are secured to the fastener driving portion and an endcap without the use of special fasteners. A belt hook is available which releasably attaches to either side of the tool.

A pneumatic rotary tool has a housing formed primarily from plastic so that the weight and price of the tool are substantially reduced. The air motor is formed for economic assembly while permitting greater structural stability should the housing deflect under an impact. The tool includes a torque selector which controls the amount of pressurized air allowed to enter the air motor, thereby controlling the torque output of the motor. The user may adjust the torque selector to a number of set positions which correspond to discrete torque values. The tool additionally incorporates early and late stage exhaust ports, so that backpressure within the air motor does not slow motor rotation or decrease tool power.
