ABSTRACT:
The present invention relates an impact tool with a twin lobed anvil, and the separate anvil, timing shaft and mating dog hammer. The impact transmission is configured in such a way so as to maintain contact between the anvil and dog hammer. As a result, the components of the present invention provide a harder blow to the anvil of an impact tool due to a larger strike surface area, provide greater torque due to increased mass at engagement, and increase the durability of the impact tool.
