DTH Hammers Description

DTH hammers are pneumatic drilling tools used primarily in mining, quarrying, construction, geothermal drilling, and water well drilling. They operate by placing the hammer directly behind the drill bit at the bottom of the hole, allowing energy to be transferred efficiently and minimizing power loss.

Key Features

• High Penetration Rates: The hammer strikes the bit with high-frequency impacts, enabling fast drilling through hard and abrasive rock.

• Energy Efficiency: Because the hammer works down the hole,  air energy is not lost in the drill string.

• Straight, Clean Boreholes: Provides excellent hole accuracy and reduces deviation in deep drilling.

• Durability: Built with hardened steel and wear-resistant components for long service life.

• Air Driven Operation: Uses compressed air to power the hammer and clear cuttings from the hole.

Typical Applications

• Mining and mineral exploration

• Water well and geothermal drilling

• Quarrying and aggregate production

• Construction and foundation work

• Oil and gas pre-split and blast hole drilling

How They Work

Compressed air flows through the drill string into the hammer, driving a piston inside it. The piston repeatedly strikes the drill bit, breaking the rock. The same airflow then carries crushed rock chips to the surface.
