ABSTRACT:
A cordless, electric or pneumatic drill device which enables user to saw in a reciprocating action. A compact metal enclosure having steel helical and worm gears together with eccentric peg to drive arm to blade, the rotation of the drill enters the tool by the removable hexagonal shaft which can be inserted into the tool at three (3) different angles depending on the task. The worm gear meshes with a helical gear having an eccentric peg that is inside an elongated slot of the blade drive armature. As the worm gear rotates its speed is exchanged for torque in the helical gear the rotation of the helical gear is converted to a linear reciprocating motion which drives the blade.
