High Air Pressure DTH380,SD8,QL80,M80 DTH Hammers and bit for drilling deep hole length
FEATURES
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 standard and other Chinese industry standards.It is durable for being produced with advanced craftwork and good material.
It also has the following advantages:
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 to maintenance due to simple, reliable
and easy assemble and disassemble inner structure of hammer.
4. Easy to depart bit from hammer due to multi—head thread
connecting chuck and cylinder of hammer.
5. Interchangeable with DTH bit and drill pipe
Applications
• Underground mining
• Tunneling
• Quarry benching operations
