1.Optimized internal‑structure reverse‑circulation DTH hammer.Optimized energy‑transfer design delivers fast penetration speed and enables stable & continuous geological sampling for exploration projects.
2.Robust simple‑structure for long service life & easy maintenance.Simple internal construction with high‑rigidity components. Extend working lifespan, convenient for field disassembly and routine servicing.
3.Integrated carburized sampling tube for quick replacement.One‑piece carburized sampling tube features high wear resistance. The tube can be replaced without dismantling the whole DTH hammer, saving operating time.
4.Patented drill bit design for multi‑borehole sizes & uncontaminated samples.One hammer matches multiple hole diameters just by changing patented bits. Effectively keep geological samples free from contamination.
5.Powerful adaptability for complex tough drilling conditions.Performs reliable sampling work in loose soil, hard rock and high‑water‑content formations, suitable for various challenging exploration sites.
