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. Valveless air distribution, more reliable.
2. Piston with simple but compact design, long life.
3. More efficient energy transfer, faster drilling speed, lower air consumption, and lower oil consumption.
4. Fewer internal parts, simple structure, longer life, less failure, and easier to maintain, with all heat-treated parts;
5. Easy to disassemble, thanks to the top sub, drive chuck and external cylinder all are connected by a multi-step thread.

For high penetration rates in soft to medium-hard and fissured rock formations.
B. 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.
C. 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.
D. 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.
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.
A. Spherical
* Application Strength, multi-purpose
* Application Strength-fast penetration
* Best suited to soft ground
* 10,000to 20,000 PSI(70 to 140 MPa)
* Non-abrasive ground
C. Semi-ballistic
* Application Strength-fast penetration
* Best suited to medium ground
* 15,000 to 25,000 PSI(100 to 170 MPs)
* Mildly abrasive ground
D. 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
