Abstract
A swinging weight assembly for an impact tool includes an anvil having an impact jaw that is reinforced with a circumferential flange. A hammer includes a hammer lug and a cam lug for pivoting the hammer between an engaged position in which the hammer lug strikes the impact jaw and a disengaged position in which the hammer moves past the impact jaw. The cam lug is separated from the cam lug to define a space in which the reinforcing flange is received.
