DTH Hammers

Center Rock Force Hammers

The Center Rock Force (RF) line is a valved DTH hammer built for drillers who need consistent power across geotechnical, water well, mining, and select oil and gas applications. With a tunable air cycle and reversible casing on most models, the RF line is built to get the most footage out of every hammer before it needs service.

All CENTER ROCK FORCE® hammers feature a high efficiency and tunable valved air cycle to optimize performance on your compressor. Most models feature reversible casings, so your team can get the most footage from your hammer. Accessories like bit retrieval systems and jetted backheads are available for high airflow deep hole applications.
