Disclosed is a 360 degree viewable flexible light band which may be readily disposed on a power tool which permits ready viewing of tool function in terms of required communication to the operator. Construction of the light band makes it readily installable and replaceable in a tool recess which may be covered by a clear lens to permit viewing.

An ergonomically adjustable handle for attachment to the body of a tool has a handle member with first and second ends with an axis between. Provision for attaching the first end of the handle to the tool body allows rotation of the handle about the axis through the attachment point. A pivot point is located on the axis of the handle member near the first end and permits deflection of the second end of the handle with respect to the first end. In addition, an outer layer portion of the handle member near the second end may be rotated about its axis to provide a comfortable position for the ellipsoidal cross section of the handle. Finally, clamping provisions at the articulation point and the two rotation mechanisms secure the handle in the desired position.

A modular reverse switch assembly having a rotating disc actuation member with a plurality of extending tabs which are spaced apart to project to opposite sides of the tool thereby permitting ease of operation by either hand. The modular design permits a wide degree of selection in assembly location and practice.

A pneumatic tool has a one-piece metal tube forming an air motor cylinder and an associated air inlet plenum. Air passages are formed between an inner housing, molded in situ about the motor cylinder tube, and an outer housing separately molded. The inner and outer housings are both formed from a non-metal composite material which contributes to operator comfort by its light weight, thermal insulation, vibration damping, and noise suppressing properties. The tool may be assembled to provide forward exhaust, rearward exhaust, or combined forward and rearward exhaust.
