Down the hole (DTH) hammer bits serve as matching drilling tools paired with DTH hammers, capable of penetrating various rock formations during borehole construction. Equipped with spline transmission structures that work alongside DTH hammers, these hammer drill bits transfer rotational force to complete underground drilling tasks. Multiple dimensional specifications and structural patterns are offered, supporting the fabrication of boreholes with diverse diameters to satisfy different construction demands.

• Versatile Structural Configurations : Three mainstream structural configurations are supplied: flat face, convex face and concave face DTH bits. These distinct designs are tailored to cope with soft rock, hard rock and highly abrasive rock strata respectively, covering all common rock drilling scenarios.
• Advanced Energy Transmission : The HD series DTH hammer adopts cutting edge rock drilling theoretical design for its internal layout, which helps transmit impact energy to DTH bits to the fullest extent. It realizes faster penetration rates while cutting compressed air consumption during drilling operations.
• Premium Material Construction : Manufactured from premium alloy steel and processed via sophisticated production techniques, these DTH hammer bits operate steadily throughout the whole service cycle and feature outstanding wear resistance for prolonged service life.
• Simplified Maintenance : The internal structure of our DTH drill bits adopts a concise and stable design, bringing fewer breakdowns on site. Operators can finish assembly and disassembly effortlessly, greatly simplifying daily maintenance work.
• Quick Tool Replacement : Multi section thread connections are adopted between the chuck and cylinder of DTH hammers, enabling quick separation of DTH bits from hammers and speeding up tool replacement on construction sites.

Our high air pressure DTH hammer bits are forged with top grade nickel alloy steel, greatly boosting overall structural toughness and anti abrasion capability for long term rock drilling. Every piece undergoes standardized precision heat treatment plus dedicated stress relief processing, which stabilizes mechanical properties and delivers steady, reliable working performance under continuous heavy load drilling conditions.

Engineered with optimized internal airflow and impact structure, these DTH drill bits maximize rock breaking efficiency while retaining powerful hole flushing capacity. They deliver outstanding penetration speed to shorten overall drilling periods on various construction sites.

High air pressure DTH drill bits fit versatile engineering and mining scenarios, widely deployed in open pit underground mining, geotechnical exploration, metallurgical projects, coal mine excavation, water conservancy infrastructure, chemical engineering foundation works, as well as highway and road construction drilling tasks.
