| High Light | DTH bits for hard rock drilling ，flat face DTH hammer tools ，carbon steel high air pressure bits | ||
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.
| Face Shape | Use Condition |
|---|---|
Concave Face | The all round application bit face specifically for medium hard and homogeneous rock formations. Good hole deviation control and good flushing capacity. |
Convex Face | For high penetration rates in soft to medium hard with low to medium air pressures. It is the most resistance to steel wash, and may reduce the load and wear on the gauge buttons, but poor hole deviation control. |
Flat Face | This kind of face shape is suitable for hard to very hard and abrasive rock formations in applications with high air pressures. Good penetration rates and resistance to steel wash. |
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.
Button shape | Use condition | |
| Domed / Round Button | Domed / Round Button are usually used as gauge buttons of DTH Bits,suitable for very abrasive and very hard formations. |
| Parabolic / Semi - Ballistic Button | Parabolic Buttons are usually used as gauge buttons and front buttons of DTH Bits,suitable for medium abrasive and hard formations. |
| Ballistic Button | Ballistic Bultons are usually used as front buttons of DTH Bits,suit-able for medium abrasive and medium hard formations.They can alsobe used as gauge buttons if the rock is soft |
| Sharp Button | Sharp Buttons are usually used as front buttons of DTH Bits for softformations where fast penetration rates are possible and button bre-akage is minimal, |
| Flat Button | Flat Buttons are usually used as protection buttons to reduce wear onrubbing surfaces of DTH Bits. |
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.
