Abstract
An expanding tool for widening pipe ends having an ergonomic design. The expanding tool uses a transmission which drives a cam offset at a distance from a motor axis to drive a number of jaws which move from a closed position to an open position to widen a pipe end. The expanding tool has a balanced positioning of components across the expanding tool's length achieving ergonomic benefits for a user.
