For high penetration rates in soft to medium hard and fissure rock formations. Low to medium air pressures. Maximum hole deviation control.

2. Concave Face
 The all-round application bit face specifically for medium hard and homogeneous rock formations. Good hole deviation control and good flushing capacity.

3. 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.

4. 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.

5. 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.

Carbide button shape selection:

1. Domed/Round Button

3. 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.

4. Sharp Button
Sharp Buttons are usually used as front buttons of DTH Bits for soft formations where fast penetration rates are possible.

5. Flat Button
Flat buttons are usually used as protection buttons to reduce wear on rubbing surfaces of dth bits.
