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.

Material selection for integral drill rods is crucial to their performance and longevity. Typically made from high-speed steel (HSS) or carbide, these rods are heat-treated to withstand the stresses of high-speed drilling and the friction generated during thread formation. HSS offers a good balance of toughness and hardness, while carbide provides superior durability and cutting efficiency, making it ideal for drilling through harder materials.
