Bit Face Shape Selection

Drop Center Bit: Ideal for high penetration rates in soft to medium hard and fissured rock formations. Operates with low to medium air pressures and provides maximum hole deviation control.
Concave Face: Versatile all-round application bit for medium hard and homogeneous rock formations. Offers good hole deviation control and excellent flushing capacity.
Convex Face: Delivers high penetration rates in soft to medium-hard formations with low to medium air pressures. Provides maximum resistance to steel wash and reduces load on gauge buttons, though with less hole deviation control.
Double Gauge Face: Suitable for fast penetration rates in medium to hard rock formations. Designed for high air pressures with good resistance to steel wash.
Flat Face Bit: Perfect for hard to very hard and abrasive rock formations in high-pressure applications. Combines good penetration rates with excellent resistance to steel wash.

Carbide Button Shape Selection

Domed/Round Button: Typically used as gauge buttons, suitable for every abrasive and very hard formations.
Parabolic/Semi-Ballistic Buttons: Used as both gauge and front buttons, ideal for medium abrasive and hard formations.
Ballistic Button: Primarily used as front buttons for medium abrasive and medium hard formations. Can also serve as gauge buttons in soft rock conditions.
Sharp Button: Designed as front buttons for soft formations where fast penetration rates are achievable.
Flat Button: Used as protection buttons to reduce wear on rubbing surfaces of DTH bits.
