Core Performance & Technical Advantages
Most conventional medium - pressure DTH hammers on the market suffer from unstable operation under slightly elevated air pressure. In contrast , the HENGLONG M - series CIR90 / M3 model adopts a self - developed patented M - type hammer head structure , which optimizes the internal impact and airflow system. This innovative design enables sustainable and flawless operation under 15Bar high - pressure conditions , achieving far better working stability than ordinary peer drilling tools.
Every critical internal wearable component is processed with precision standardized heat treatment technology , effectively boosting structural rigidity , impact resistance and wear resistance. This sophisticated craft greatly prolongs the overall service cycle of the drilling hammer. Meanwhile , the optimized internal airflow circulation and impact transmission structure greatly reduces air loss , delivering lower air consumption and greatly improved drilling efficiency. In actual rock drilling work , this tool boasts faster rock breaking efficiency , higher drilling hole precision and more reliable overall drilling quality.
Even with high - efficiency rock breaking performance , the hammer is designed with optimized vibration and noise reduction structures , supporting long - hour uninterrupted construction in harsh and complex geological environments. It excels in drilling medium - hard rock , sandstone and conglomerate formations , effectively solving the industry ' s common points such as slow drilling progress , easy component abrasion and unstable working status of traditional down - the - hole hammers.
Wide Industrial Application Scenarios
Featuring excellent versatility and high cost - performance , the CIR90 / M3 medium - pressure down - the - hole hammer fits a wide range of engineering drilling scenarios. It is widely applied in domestic and overseas water well drilling , open - pit mining exploitation , municipal infrastructure construction , stone quarrying and geological prospecting projects. No matter for small - scale temporary drilling tasks or large - scale continuous engineering construction , the HENGLONG M - series DTH hammer can maintain stable and efficient performance , helping enterprises cut operating costs and accelerate project completion.
