Demolition hammers are similar to rotary hammers and are used in the same way in terms of delivery hammer blows. However, demolition hammers deliver hammering action only, unlike rotary hammers, which can also be used to bore holes.

What demolition hammers lack in this regard in terms of versatility, however, they make up in punch. The demolition hammer is able to deliver more powerful blows than rotary hammers, since they typically have about 35% more power. This is due to the fewer parts in a demolition hammer, and sometimes a longer piston stroke, as well. 

While the demolition hammer delivers fewer blows per minute than a rotary hammer, the increased strength of the tool actually makes it a quicker and more efficient means of demolishing concrete and masonry.
