Working Principle

The Kaishan M3AK DTH hammer operates on the principle of compressed air driving a piston inside the hammer. High-pressure air is supplied through the drill pipe to the hammer. The air pushes the piston forward, striking the drill bit with high impact energy. The bit then crushes the rock, and the exhaust air flushes the cuttings out of the hole. The piston returns due to air pressure and the cycle repeats rapidly, creating continuous impacts. The hammer's design ensures efficient energy transfer to the bit, maximizing drilling speed while minimizing air consumption. The simple yet robust mechanism reduces wear and tear, extending the hammer's service life. This makes the M3AK a reliable and cost-effective tool for demanding drilling applications.
