The heart of a rotary jack hammer is its hammer mechanism, which houses a piston that moves back and forth at high speed. When activated, this piston strikes a steel anvil, creating a force that's transferred to the bit, causing it to hammer into the material with great force. The bit, usually made of durable materials like tungsten carbide, can be replaced depending on the job at hand, ranging from flat chisels for general demolition to pointed bits for drilling holes.

  • In addition to extending the reach of the core drill bit, extension rods also play a crucial role in maintaining the stability and alignment of the drill bit during operation. This is especially important when drilling in hard or uneven surfaces, where maintaining a straight and consistent drilling trajectory is essential for achieving accurate results. The extension rod helps to absorb vibrations and ensure that the drill bit remains in place, reducing the risk of deflection or deviation from the desired drilling path.
