A rock breaker is a machine attachment designed to manipulate large rocks, including reducing large rocks into smaller rocks. Rock breakers are typically used in construction, demolition and  mining industries to remove oversize rocks that are too large or too hard to be reduced in size by a crusher or the demolition of concrete and other hard surfaces.

A rock breaker is a powerful percussion hammer, typically fitted to an excavator, skid steer loader, backhoe or mini loader for demolishing concrete structures or rocks. It is powered by an auxiliary hydraulic system from the carrier.
