Bit Face Shape Selection

Bit Face Shape Selection

Changsha Tianhe Drilling Tools and Machinery Co., Ltd. offers a range of bit face shapes designed to cater to various rock formations and drilling conditions.

Drop Center Bit

Ideal for achieving high penetration rates in soft to medium hard and fissured rock formations. This bit is suitable for low to medium air pressures and provides maximum hole deviation control.

Concave Face

Designed for all-around applications in medium hard and homogeneous rock formations. The concave face bit offers good hole deviation control and flushing capacity.

Convex Face

Offers high penetration rates in soft to medium-hard formations with low to medium air pressures. This bit is resistant to steel wash and reduces load and wear on gauge buttons. However, it may have poor hole deviation control.

Flat Face

Suitable for hard to very hard and abrasive rock formations with high air pressures. The flat face bit provides good penetration rates and resistance to steel wash.

Features
