I think you might be referring to a "demolition hammer" or a "building breaker"!

Here's an image of a typical building breaker:

Building breakers, also known as demolition hammers, are powerful tools used to break up and demolish structures, such as concrete walls, floors, and foundations. They are typically used in construction and demolition projects to clear out old buildings, prepare sites for new construction, and remove unwanted structures.

Would you like to know more about building breakers or is there something else I can help you with?
