Working Principle

The Kaishan M30K DTH drill bit operates on the principle of down-the-hole percussion drilling. High-pressure air is delivered through the drill string to the DTH hammer, which drives the bit's piston in a rapid reciprocating motion. This piston strikes the bit's shank, transferring impact energy to the tungsten carbide buttons. The buttons penetrate the rock, creating fractures and chips. Simultaneously, the rotation of the drill string indexes the bit, allowing the buttons to attack fresh rock surfaces. The air also serves as a flushing medium, blowing the rock cuttings out of the hole through the annulus. The M30K's flat face with center blow hole ensures efficient cuttings removal, preventing regrinding and enhancing penetration rates. The combination of impact, rotation, and flushing makes DTH drilling highly effective in hard rock, and the M30K is engineered to maximize this efficiency through its robust construction and optimized button layout.
