Main Components
- Alloy steel bit body
- Carbide buttons
- Bit face
- Flushing holes
- Air passages
- Shank adapter
- Retaining ring
- Wear-resistant coating
Working Principle
DTH drill bits work with a down-the-hole hammer that is driven by compressed air. The hammer piston strikes the bit shank at high frequency, transferring impact energy to the carbide buttons on the bit face. As the bit rotates slowly, the buttons crush and fracture the rock. Compressed air then flows through the bit's flushing holes to remove cuttings from the hole bottom and carry them to the surface. The combination of impact, rotation, and flushing enables efficient drilling in hard rock. The Kaishan M3 is designed to optimize this process with a robust body, precisely positioned buttons, and large air passages, ensuring effective energy transfer and fast hole cleaning.
