Abstract
An anvil is disclosed having wings with additional surface area compared to prior art impact wrench anvils. The wings engage respective hammers in a radial direction, and overlap with one another in an axial direction across the interface between the two hammers. The hammers can each include a recess so that one wing does not engage the hammer associated with the other wing. In an embodiment, the surface of the wing can be angled to increase the amount of material extending over the hammer interface.
