Advanced Performance Features
ROSCHEN DTH air hammers feature a unique airflow design that maximizes performance, delivering more power down the hole for increased productivity. As a pneumatically operated valveless percussion drill, the DTH hammer uses air to drive the piston, striking the bit with high-impact force capable of penetrating extremely hard formations.
Versatile Application Compatibility
The ROSCHEN DTH hammer can be mounted on various drilling machines with top head or Kelly drive configurations. Applications include heavy construction, mining, oil and gas, quarries, and water well drilling.
Enhanced Durability Design
The Roschen Hammer Line features increased wear sleeve wall thickness, significantly extending service life and reducing maintenance requirements.
