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
