Working Principle

The Kaishan L2 DTH drill bit operates on the principle of down-the-hole percussion. Compressed air is fed through the drill string to the DTH hammer, which houses a piston that strikes the bit's shank at high frequency. This impact energy is transferred through the bit body to the carbide buttons, which crush and fracture the rock. Simultaneously, the exhaust air flows through the bit's flushing holes to remove cuttings from the hole bottom, preventing regrinding. The bit rotates slowly, indexing the buttons to new positions for even wear. The combination of impact, rotation, and flushing enables efficient drilling in hard rock. The L2's design optimizes this process by ensuring maximum energy transfer and effective cuttings evacuation, resulting in high penetration rates and extended bit life.
