The ST350 Air Borewell Drilling Machine is engineered to deliver consistent, high-speed drilling capability across diverse geological conditions. Its advanced hydraulic architecture provides smooth operation while the high-capacity air system ensures deep penetration in hard rock formations. Contractors value its fast setup time and minimal maintenance requirements.
The ST-350S series drilling rig is an efficient and versatile drilling equipment primarily used for wells, agricultural irrigation wells, geothermal air-conditioning holes, and other well applications. It is especially suitable for water intake projects in mountainous and rock formations. The efficiency is ten times higher than traditional rotary drilling rigs, creating impressive economic benefits for users. It effectively solves the difficulty of drilling in soil with DTH hammer and addresses construction problems with hard rock layers, gravel, and pebble layers, working efficiently under various geological structures.
