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.

Small drill bits, often ranging from fractions of an inch to around ¼ inch in diameter, come in a variety of materials and shapes to cater to different tasks.

Each type is a specialized tool, much like a chosen word that perfectly fits the context of a sentence.
