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
