We can design and manufacture according to customer's requirement of the bit dia, no.of air holes, carbide button shape and face shape.

 

How to choose a DTH bits for your demand:

 

How to Select DTH BITS FACE SHAPE AND 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)

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
