1.High‑pressure DTH hammer for hard rock drilling.Designed for high working air pressure, delivers powerful impact energy for drilling granite and other extra‑hard rock formations.
2. Stable performance & high drilling efficiency.Optimized internal structure, strong impact frequency, fast penetration rate for blast hole, water well and mining drilling projects.
3.Reasonable air consumption design.Good cuttings discharge capacity, lower risk of stuck hammer even for deep‑hole drilling conditions. Matches high‑pressure air compressor.
4.Durable valveless structure.Less vulnerable wearing parts, easy disassembly and field maintenance, long service life under harsh mining site environment.
5.Multiple sizes available high‑pressure DTH hammer.Covers hole diameter range 90‑254mm, compatible with standard high‑pressure DTH drill bits for convenient tool replacement.
