ABSTRACT:
A high speed rotary hand tool with an adjustable head coupling allows the tool head to be operated at extremely high speeds in a preselected angle in relation to the tool body. A coiled, flexible power drive is carried through a spherical head to transfer power from the motor drive to the tool drive. The spherical head has formed detent recesses in which detent balls are held by a combination of leaf springs and a locking sleeve. A safety pin and groove mechanism prevent the sleeve from being inadvertently released.
