The heart of a jack hammer is its hammer mechanism, which rapidly strikes a chisel or bit, capable of breaking through even the toughest concrete and rock. This mechanism is powered by either an electric motor or a compressed air system, providing the raw force needed for heavy-duty tasks. The versatility of jack hammers is further enhanced with interchangeable bits, allowing them to be used for drilling, chiseling, and even digging.
