Bit Face Shape Selection

Drop Center Bit

For high penetration rates in soft to medium hard and fissured rock formatios 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 fIushing capacity

Convex Face

For hiigh penetration ratas m soft to medium-hard wlth low to medium air pressures It is the most rasistance 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 aii 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 appllications with high air pressure. Good penetration rates an resistance to steel wash.

carbide button shape selection

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 and

Flat Button

Flat buttons are usually used as protection buttons to reduce Near on rubbing surfaces of DTH Bits.
