Production Description
With professional manufacturing experience in DTH hammer production, our factory can supply you with high pressure and medium to low-pressure DTH hammers. It strictly matches with API standards and other Chinese industry standards.It is durable for being produced with advanced craftwork and good material.
Our hammer and bits are made of high-quality alloy steel with advanced heat treatment to assure good drilling performance and long service life. They are widely used by our customers all over the world.
Advantage:
1. Deliver maximum energy to drilling bit, fast drilling speed, and low air consumption due to the special inner structure of HD series DTH hammer designed according to newest rock drilling theory.
2. Smooth performance and long service life of HD series DTH hammer due to high-quality alloy steel materials and advanced processing technology adapted.
3. Low problem rate and easy maintenance due to simple, reliable, and easy assemble and disassemble inner structure of hammer.
4. Easy to depart a bit from hammer due to multi-head thread connecting chuck and cylinder of hammer.
5. Interchangeable with DTH bit and drill pipe.
