Our hammers are meticulously engineered to deliver exceptional performance, setting new industry standards. Utilizing the industry-standard REMET and METZKE threads, our hammers ensure flawless airflow, surpassing expectations in global drilling operations, particularly in the Nordic region, where continuous operation is maintained even after drilling depths of up to 250 meters.
At Starockdrill, we continuously optimize our product design to ensure our reverse circulation hammers excel in both dry and wet working conditions. With outstanding performance capabilities, our hammers provide reliable operation and robust support when encountering underground voids and water levels.
