14" DTH HAMMER

DTH HAMMERS

Down-the-hole (DTH) hammers are precision-engineered pneumatic tools designed for efficient rock drilling in mining, construction, and geotechnical applications. These hammers operate by forcing compressed air down the drill string to the hammer, where it energizes a piston, delivering powerful blows to the drill bit, facilitating fast and effective penetration into hard rock formations.
