ABSTRACT:
A rotating dual attachment receptacle apparatus tool which allows the operator to use more than one tool accessory without the need of frequent changing of the drilling, driving or fastening accessory. The rotating apparatus tool has three (3) major parts: a stem grip housing having a motor and power means disposed therein; a safety guard housing attached to one end of the stem grip housing and a rotating drill head assembly disposed within the safety guard housing. The rotating drill head assembly has two (2) conventional drill chucks located at opposite ends thereof and is held in place within the cavity of the safety guard housing by means of a main drive shaft which extends from the top inside portion of the safety guard housing into the stem grip housing. The rotating drill head assembly is so constructed that it can be rotated in a 360 degree plane about the longitudinal axis of the main drive shaft. Said rotating drill head assembly can be locked or unlocked by locking means consisting of two (2) release buttons located on its sides. The locking mechanism for saafety reasons is so constructed that unless both release buttons are pressed simultaneously it will not unlock the drill head. When the drill head assembly is rotated it will disengage the power means to prevent accidental operation of the rotating apparatus tool chucks.
