An engine-powered torque wrench (18) has a loop handle (19) that is orthogonal to a torque rod (22) of a torque handle. The engine-powered torque wrench has a heat engine (1) which rotates a toolhead (14) to which selected tools (25) or a striker gear (16) which can hold the selected tools is attachable. The loop handle is adapted to be hand-grasped by a first hand of a user for primary support of a system weight of the engine-powered torque wrench while selectively positioning a selected tool on a targeted item (23) which typically but not necessarily includes a fastener head (24). The torque handle is adapted to be hand-grasped by a second hand of the user for secondary support of the system weight while simultaneously using the second hand for assisting in positioning of the selected tool, leveraging against rotational moment of the tool heat engine and throttling heat engines which are not preset-throttled. The engine-powered torque wrench can be adapted for either right-handed or left-handed use and for either right-side access or left-side access to the targeted item.

A pneumatic tool is disclosed which includes vibration mounts to reduce the amount of vibration transferred to the user. The vibration mounts include a pair of support members and at least one resilient vibration isolator connecting the support member in a spaced relationship. A compressed air conduit passes through the support member openings but is only directly fastened to one of the support members.

The present invention relates to a power tool having a housing, a handle having an inlet passage and an outlet passage extending therethrough, and a pneumatic pressure seal/vibration isolator positioned between the handle. The present invention provides a tool that has an excellent handle to housing seal and does not exhibit heavy vibrations. The present invention is also the vibration isolator that seals the handle to the motor housing and reduces vibrational transmissions to a user. Also disclosed is a power tool having a vibration isolator coupled to the housing and handle, and a mechanism for allowing sliding rotation of the handle relative to the vibration isolator, thereby allowing the handle to point in a different direction other than toward the point of impact. The present invention also discloses a pneumatic power tool including a handle, a housing having a first longitudinal axis, and a vibration isolator rotatably coupling the handle to the housing, the vibration isolator including a central opening through which air passes that is not aligned with the first longitudinal axis.

A replaceable, flexible and resilient grip is slidably fitted over a generally cylindrical handle portion of a power hand tool housing. In one embodiment, for use with a pistol grip housing with a separable end cap, the grip has a flange which is clamped between the end cap and the barrel of the housing and has lugs which fit in recesses in the barrel and end cap. The grip also has a strap portion which fits between the trigger and the barrel and a flange which fits in a groove adjacent to the barrel. In another embodiment, the tool has an air exhaust port adjacent to the handle portion and the grip defines an exhaust air passage alongside the handle portion, the grip being held in place by a retaining plate.
