High-Performance DTH Hammer for Rock Drilling

DTH Hammer is designed for efficient down-the-hole drilling in rock formations where high impact energy, stable penetration and reliable drilling performance are required. The hammer works together with a matching DTH button bit to deliver repeated impact directly at the bottom of the borehole, helping achieve efficient penetration in rock formations.

Available in 90, 115, 140, 152 and 165 mm sizes, with different gauge and face button configurations to match drilling diameter and formation conditions. Custom button arrangements and configurations are available according to drilling requirements.

Applications & Formations

Used across water well, mining and quarry drilling

DTH hammers are widely used for water well drilling, geothermal drilling, mining drilling and quarry drilling. Other applications include blast hole drilling, foundation drilling, construction drilling and rock drilling projects.

01 Water Well Drilling Efficient penetration for water well projects in medium-hard to hard rock.	02 Mining Drilling Reliable impact drilling for mining and blast hole drilling operations.
03 Quarry Drilling Stable borehole performance for quarry and rock extraction projects.	04 Geothermal Drilling Efficient penetration for geothermal borehole and energy projects.

Suitable Rock Formations

DTH drilling systems are commonly used for medium-hard to hard rock drilling applications. Typical formations can include the following.

Limestone	Dolomite	Sandstone	Granite
Basalt	Marble	Gneiss	Other Hard & Compact Rock

⚠️ Note: The final hammer and button bit configuration should be selected according to rock hardness, abrasiveness, borehole diameter and drilling equipment.

Available Button Configurations

Gauge-button and full-button configurations

The final selection depends on rock hardness, abrasiveness, borehole diameter and drilling speed requirement.

Gauge-Button

Gauge-Button Configuration

Uses carbide buttons mainly around the outer gauge and selected face positions, suitable for projects requiring stable gauge protection and efficient rock breaking.

Full-Button

Full-Button Configuration

Uses a denser carbide button layout across the bit face for stronger rock contact and increased cutting coverage.

Available Sizes

Five standard DTH hammer sizes

Each size is matched to a different borehole diameter range and drilling application.

90 mm DTH Hammer Compact configuration for smaller borehole drilling.	115 mm DTH Hammer Suitable for general water well and engineering drilling.	140 mm DTH Hammer Designed for medium-diameter rock drilling projects.
152 mm DTH Hammer Suitable for larger borehole and water well applications.	165 mm DTH Hammer Heavy-duty option for larger-diameter drilling projects.	Custom Sizes Other diameters available on request.
