Demolition hammer, also known as a jackhammer. It is a heavy-duty power tool used for breaking up concrete, asphalt, and other hard materials.
Demolition hammers are available in various sizes and power levels, from light-duty for small jobs to heavy-duty for large-scale construction projects.
They are typically powered by electricity, compressed air, or hydraulics.
Electric demolition hammers are often used for indoor renovation projects because they are quieter than other types.
The tool works by combining a hammer mechanism with a chisel to deliver powerful blows.
