How does a power hammer work?
A typical power hammer consists of a frame, an anvil, and a reciprocating ram holding a hammer head or die. The workpiece is placed on the lower anvil or die and the head or upper die strikes the workpiece. The power hammer is a direct descendant of the trip hammer, differing in that the power hammer stores potential energy in an arrangement of mechanical linkages and springs, in compressed air, or steam, and by the fact that it accelerates the ram on the downward stroke. This provides more force than simply allowing the weight to fall. Predecessors like trip hammers, steam drop hammers, board or strap hammers, used the power source to raise the ram or hammer head, but let it fall solely under gravity.

What is a Dead Blow Hammer?
This has all the appearance of a traditional mallet and is often made from hardened plastic. However, the main difference between a dead blow hammer and a rubber mallet is that inside the head of the hammer are iron shots that can move freely when the hammer is in motion. The force exerted by the heavy iron shots reduces the recoil considerably.
Dead Blow Hammer Uses
This type of hammer may be used conventionally, but because the force is spread over a longer period of time it is mostly not used for traditional nailing where speed is of the essence. However, because of the lack of elastic rebound, the dead blow hammer does offer a wide variety of uses in many different industries which include the following.
Advantages of Dead Blow Hammers
