Product Details

O Kaishan K40 é uma broca de botões para martelo de fundo de furo na linha de ferramentas de perfuração, servindo como extremidade de corte da coluna DTH em rocha dura e abrasiva. Seu corpo em aço liga carrega botões de carboneto de tungstênio em uma face plana ou convexa, com haste estriada, furos de lavagem e anel de retenção. O impacto da haste do martelo DTH passa pelos botões enquanto o ar comprimido remove os detritos, adequando-se a trabalhos de mineração, pedreira, poço de água e geotermia. Ele se combina com martelos e hastes DTH padrão, e a Kaishan o respalda com garantia, suporte técnico, peças de reposição e treinamento de operadores.

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.
