Machine
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.

How to Select Threaded Button Bits Face shape and Carbide Button
Shape
Drop Center
For high penetration rates in soft to medium-hard and fissured rock
formations.
Concave Face
The all-round application bit face specifically for a medium-hard
and homogeneous rock formation. Good hole deviation control and
good flushing capacity.
Convex Face
For high penetration rates in soft to medium-hard with low to
medium air pressure. It is the most resistant to steel wash, and
good resistance to steel wash step gauge bit.
Flat Face
This kind of face shape is suitable for hard to very hard and
abrasive rock formations in applications with high air pressures.
Good penetration rates and resistance to steel wash.
B: Insert Carbide Button shape Selection
The different button is ideal for different ground conditions,
abrasive levels, and penetration levels. In general, the more gauge
buttons, the better over performance, especially in hard rock.
Spherical* Application Strength-multipurpose
* Best suited to soft abrasive
* 25,000 to 45,000 PSI (170 to 300 MPa)
* Abrasive to very abrasive
Ballistic Button
* Application Strength- fast penetration
* Best suited to soft ground
* 10,000to 20,000 PSI(70 to 140 MPa)
* Nonabrasive ground
Semi-ballistic
* Application Strength-fast penetration
* Best suited to medium ground
* 15,000 to 25,000 PSI(100 to 170 MPs)
* Mildly abrasive ground
Wedged (Conical) Button
* Application Strength- fast penetration
* Suited for all non-abrasive ground types
* Smaller contact area
* Best suited for smaller diameter bits
Features of our Threaded Button Bits:
* Be produced from premium quality Nickel-alloy steel or
Molybdenum-ally steel for increased durability and wear
characteristics
* Specific heat treatment standards and strict production process
ensure consistent performance
