Patent ID: 7062979

Claim:
A portable torque tool comprising: a motor for applying torque to a threaded fastener; at least one battery for providing power to said motor; a torque transducer for providing a measure of the torque applied to the threaded fastener; and a processing element for at least partially controlling operation of said motor, said processing element to control a speed of said motor to advance the threaded fastener at a first rate, to receive the measure of torque applied to the threaded fastener and configured to determine that the torque applied to the threaded fastener has reached a predefined threshold and to thereafter reduce the speed to said motor that is otherwise capable of continuing to operate at a greater speed sufficient to advance the threaded fastener at the first rate such that the threaded fastener is advanced at a second rate that is slower than the first rate at which the threaded fastener was advanced prior to determining that the torque applied to the threaded fastener had reached the predefined threshold.
