DTH380 Water Well Drilling DTH Hammer
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
Specification
Dth rock drill bits are in different sizes ranging from 3" to 12".
Dth rock drill bits are available in valveless model and is competent to operate in harsh conditions
DTH rock drill bits have four kinds of button type
Spherical button : good wearing resistance, suited to hard ground, abrasive to very abrasive.
Parabolic button : fast penetration,suited to medium to hard rock,suitable for the mildly abrasive ground.
Conical button : fast penetration, suited for smaller diameter bits, suited for all non-abrasive ground types.
Ballistic button : fast penetration,suited to soft rock, suitable for non abrasive ground
Applications of DTH Bit
• Underground mining
• Tunneling
• Quarry benching operations
