How to choose drill teeth

1、 Classification of drilling rig teeth

1.Drilling teeth: Used for drilling operations, usually conical or spherical drilling teeth, which can be matched according to requirements such as well depth and logging data.

2. Ground engineering drilling teeth: used for drilling in formations such as silt, loess, sandstone, etc., can be trapezoidal teeth, patterned teeth, or cutting teeth.

3. Mining drill teeth: Drill teeth used for mining minerals, usually spherical drill teeth, triangular drill teeth, or trapezoidal drill teeth.

2、 Selection method of drilling gear for drilling rig

1. Choose the appropriate type of drill bit based on the geological strata, and implement the principle of "coarse drilling and coarse grinding, fine drilling and fine grinding".

2. Choose the appropriate drill tooth size based on the well depth and drilling rig type to avoid low work efficiency or shortened drilling rig service life caused by drill bits that are too large or too small.

3. Based on the production requirements and economic benefits of the drilling rig, taking into account the service life and price of the drill teeth, select the drill teeth with the highest cost-effectiveness.

3、 Precautions for drilling rig teeth

1. Before use, check if the drill teeth are intact and undamaged. Losses caused by broken teeth are unacceptable.

2. During the drilling process, pay attention to maintaining a certain amount of coolant flow and pressure to avoid overheating and excessive wear of the drill teeth.

3. Avoid using worn-out drill teeth, which not only affects efficiency but also increases maintenance costs.

4. Operate according to the prescribed operating procedures, especially when transferring drilling tools underground. Failure to pull and hang according to regulations may result in loss of drilling tools and drill teeth.

5. Before stopping the machine, the drill teeth and drill bit should be clean
