Product Description

High air pressure DTH hammer is designed for percussive drilling in rock formation, characterized by high air pressure and high efficiency. Using compressed air to drive the piston, it generates high impact energy for rapid penetration. It is widely used in mining, quarrying, construction, and water well drilling industries.

Key Advantages

Maximum Energy Transfer: Inner structure designed according to newest rock drilling theory for fast drilling and low air consumption.
Premium Materials: High quality alloy steel and advanced processing for long service life.
Low Maintenance: Simple, reliable, and easy to assemble/disassemble inner structure.
Versatile Connection: Multi-head thread connecting chuck and cylinder for easy bit replacement.
Interchangeability: Fully compatible with standard DTH bits and drill pipes.

Main Applications

High pressure drilling rigs & Water well drilling
Bench drilling & Civil Engineering applications
Mining & Mineral Exploration
Oil well drilling
