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 

 

DTH Bit 

 

DTH bit is our main product. After mang years search, we have rich experience in development and manufacturing high quality products, which adopted high-quality raw materials, advanced technology and passed through strictly inspection.  

1.high and low air pressure down-the-hole drill bits 
2.Low air pressure holeDia.:65-220mm  

3.High air pressure hole Dia.:85-305mm   

4.Face type:drop center/concave/convex/double gauge/flat   

5.Our DTH Bit can be suitable for many types of DTH Hammer, such as XL, Mission, COP, IR, Mach, Demag, SD, Bulroc, Halco Mach, Digger etc.

---------------------------------DTH BIT FACE SHAPE & CARBIDE BUTTON SHAPE--------------------

 

A: Bit face shape selection

DropCenter Bit
For high penetration rates in soft to medium-hard and fissured rock formations. Low to medium air pressures. Maximum hole deviation control.
Concave face
The all-round application bit face specifically for medium hard and homogenerous rock formations. Good hole deviation control and good flushing capacity.
Convex face
For high penetration rates in soft to medium-hard with low to medium air pressures. It is the most resistance to steel wash, and may reduce the load and wear on the gauge buttons, but poor hole deviation control.
Double Gauge face
This kind of face shape is suitable for fast penetration rates in medium to hard rock formations. Designed for high air pressures and good resistance to steel wash step gauge bit.
Flat Face Bit
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 an resistance to steel wash.

 

B: Insert Carbide Button Shape Selection

 

Matching the insert to the job requirements is essential in achieving the desired results.  Different buttons is ideal for different ground conditions, abrasion levels, PSIs and penetration levels.  In general, the larger the number of gauge buttons the better overall performance, especially in hard rock.

 

Hemispherical
• Height 0.5 Ø

Ballistic Button
• Height 0.75 Ø

• Application Strength - fast penetration

• Best suited to soft ground

• 10,000 to 20,000 PSI (70 to 140 MPa)

• Non abrasive ground
Parabolic Button (semi ballistic)
• Height 0.6 Ø

• Application Strength - fast penetration

• Best suited to medium ground

• 15,000 to 25,000 PSI (100 to 170 MPa)

• Mildly abrasive ground
Conical Button
• Height 0.65 Ø

• Application Strength - fast penetration

• Suited for all non-abrasive ground types

• Smaller contact area

• Best suited for smaller diameter bits
