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
