ST350 Drilling Dth Water Well Drilling Rig 92 Kw Diesel Engine Pneumatic
The ST350 pneumatic water well drilling rig is a crawler-mounted down-the-hole pneumatic percussion rotary drilling machine featuring a rated maximum drilling depth of 350 meters. Designed for high-efficiency well drilling in hard rock formations, most models support dual air-water drilling modes. It is the most commonly used medium-deep hole drilling equipment for domestic water intake, irrigation wells and hot spring wells in mountainous and rocky areas. Driven by an air compressor to power the DTH hammer for rock breaking, it delivers far higher drilling efficiency than traditional mud drilling rigs.
