drill bits face shape selection

Bit Face Shape Selection	Brief introduction
Drop Center 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 homogeneous rock formations. Good hole deviation control and good fishing capacity.
Convex Face	For high penetration rates m soft to medium-hard with low to medium air pressures. It is the most resistance to steel wash. And many reduce the load and wear on the gauge buttons. But poor hole deviation control.
Double Gauge Face	This kind 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 pressure. Good penetration rates are resistance to steel wash.

 
drill bits carbide button shape selection

Carbide button shape selection	Brief introduction
Domed/Round Button	Domed /Round Buttons are usually used as gauge buttons of DTH Bits. Suitable for very abrasive and very hard formations.
Parabolic/Semi- Ballistic Buttons	Parabolic Buttons are usually used as gauge buttons and front buttons of DTH Bits, suitable for medium abrasive and hard formations.
Ballistic Button	Ballistic Buttons are usually used as front buttons of DTH Bits, Suitable for medium abrasive and medium hard formations. They can also be used as gauge buttons if the rock is soft.
Sharp Button	Sharp Buttons are usually used as front buttons of DTH bits for soft formations where fast penetration rates are possible.
Flat Button	Flat buttons are usually used as protection buttons to reduce Near on rubbing surfaces of DTH Bits.

 
Besides, we have a wide range of rock drilling tools for drilling projects, including DTH Hammer, DTH Bit(Hammer bit), RC Hammer, RC Bit, drill pipe; Overburden drilling systems, symmetrix system; retrac button bit, shank adapter, coupling sleeve, drill rod; tricone bits, drill collar etc.
