During the construction of rotary drilling rigs, the selection of bits directly affects the drilling effect. Shanghai Yulin provides you with a comprehensive bit selection guide.

For soft soil layers, such as clay and silty soil, a bucket - type bit can be selected. Its cutting edge is relatively wide and can effectively cut the soil. We have various specifications of bucket - type bits.

In sandy soil layers, a screw bit is more effective as it can carry the sandy soil out of the hole to prevent hole collapse. The design of our screw bit is reasonable, and the sand discharge is smooth.

When encountering hard rock formations, a roller bit or a pick bit is required as they have strong crushing ability. The hard - rock bits of Shanghai Yulin are highly wear - resistant.

Under complex geological conditions, a combined bit can be selected according to the actual situation to meet the drilling requirements of different strata. We provide customized combined bit services.
