Product Details

Le Kaishan L3 est un trépan à boutons pour marteau fond de trou de la série basse pression, l'extrémité de coupe du train de tiges DTH pour les travaux miniers, de carrière et de forage d'eau. Son corps en acier allié porte des boutons en carbure de tungstène, avec des trous de lavage et des cannelures qui s'engagent dans le mandrin du marteau. L'impact du piston du marteau passe par les boutons tandis que l'air évacue les débris. Il convient au granite, au basalte et au calcaire, s'associe aux marteaux et tiges DTH standard, et bénéficie d'un support technique, de pièces de rechange et d'une formation des opérateurs.

Working Principle

The Kaishan L3 DTH drill bit operates on the principle of down-the-hole hammer drilling. Compressed air is delivered through the drill string to the DTH hammer, which contains a piston that reciprocates at high frequency. The piston strikes the bit's shank, transmitting impact energy to the tungsten carbide buttons. Simultaneously, the bit is rotated slowly by the drill rig. The combination of impact and rotation causes the buttons to fracture the rock through a process of crushing and chipping. The air then flows through the bit's flushing holes, carrying rock cuttings up the annulus to the surface. The L3's design ensures that impact energy is efficiently transferred to the rock, while the air passages are optimized to prevent blockage and minimize pressure loss. The bit's splines engage with the hammer's chuck to transmit rotation without slippage. This method allows for high penetration rates in hard rock with minimal energy loss.

Packaging & Shipping

Each Kaishan L3 DTH drill bit is individually packed in a wooden case or carton, with rust-preventive coating applied to threads and splines. Bits are then palletized and wrapped for container shipment. Standard export packaging ensures protection during transit. Delivery time is typically 15-30 days after order confirmation, depending on quantity. Ports of shipment include Ningbo, Shanghai, or as per customer request. We can accommodate FCL and LCL shipments.

After-Sales Service

Kaishan provides a 12-month warranty against manufacturing defects. Our 24-hour technical support team is available to assist with product selection, troubleshooting, and optimization. We offer on-site training for operators and maintenance personnel. A global network of spare parts warehouses ensures fast delivery of replacement bits and components. Customized solutions and OEM services are available upon request.
