Product Details

El Kaishan K40 es una broca de botones de martillo en fondo (DTH) dentro de la línea de herramientas de perforación, y constituye el extremo de corte de la sarta DTH en roca dura y abrasiva. Su cuerpo de acero aleado porta botones de carburo de tungsteno en una cara plana o convexa, con un vástago estriado, orificios de lavado y anillo de retención. El impacto del vástago del martillo DTH se transmite a través de los botones mientras el aire comprimido evacua los detritos, lo que lo hace adecuado para minería, canteras, pozos de agua y trabajos geotérmicos. Se acopla con martillos y varillas DTH estándar, y Kaishan lo respalda con garantía, soporte técnico, repuestos y capacitación del operador.

Working Principle

DTH (Down-The-Hole) drill bits operate at the bottom of the drill string, directly impacting the rock with high-frequency percussion. The bit is connected to a DTH hammer, which is powered by compressed air. The hammer's piston strikes the bit's shank, transmitting energy to the tungsten carbide buttons that crush and fracture the rock. Simultaneously, the bit rotates slowly, allowing the buttons to engage fresh rock surfaces. Compressed air is directed through flushing holes in the bit to lift cuttings to the surface, keeping the hole clean. The K40 bit's design optimizes this process by ensuring efficient energy transfer, uniform button wear, and effective hole cleaning, resulting in high penetration rates and extended service life.
