The Twin Hammer mechanism has two identical hammers delivering simultaneous balanced impacts. This design is an improvement over other mechanisms, reducing vibration and delivering greater torque—it is very durable and widely used for industrial and heavy applications. It is used with machines for intense use, high torque, and industrial use. Maximum torque 400 ft-lb. The Twin Hammer mechanism has two identical hammers delivering simultaneous balanced impacts.
