The improved power tool includes a housing having a motor located in the housing and a rotatable tool drive shaft projecting from the housing. A torque reaction bar is attached to the housing and is engageable with a stationary object to prevent rotation of the housing relative to a threaded fastener or the like being operated upon. A tool handle rotatably encircles the housing permitting the positioning of the handle in any desired position relative to the housing and, due to the swivel or pivoting relationship, preventing the imposition of torque on the handle.
