In military engineering,
which demands high concealment, эффективность,
and safety,
down the hole drilling rig play a key role in tunnel excavation and bunker construction.
Military projects need extensive drilling done quickly while ensuring quality and safety.
DTH drills feature strong mobility and low noise, fitting the covert construction needs of military engineering. They can drill 80-120mm diameter and 3-5m deep blast holes under different geological conditions, used for tunnel blasting excavation and bunker reinforcement.

Specifically:
- Their fast drilling capability and reliable performance ensure military projects finish on schedule.
- The low-noise design supports covert operations, meeting military concealment requirements.
- Adaptability to various geologies allows efficient construction for combat and defense needs.down the hole drilling rig
