Abstract
A drill having a variable speed trigger and logic circuit which can control the direction and speed of rotation. In an alternating mode of operation, the logic circuit alternates the direction of motor/chuck rotation on each successive activation of the trigger. The drill can also be set to rotate in either a forward or reverse direction without the alternating feature. A pair of lights provide visual confirmation that the drill is set to rotate in either a forward or reverse direction. The drill can also be set in a safe mode to prevent rotation in either direction.
