Carbide Drilling Tools Spherical DTH Button Drill Bits For Mining 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
