Before use, it must be confirmed that the drill bit and the drill rod fit well, and the taper is exactly the same. The drill bit and drill rod used should be produced by the same company, otherwise the drill bit will be easily lost during use.

1. Before use, it must be confirmed that the drill bit and the drill rod fit well, and the taper is exactly the same. The drill bit and drill rod used should be produced by the same company, otherwise the drill bit will be easily lost during use.

2. In the initial stage of the drilling operation of the rock drill, the air volume should be lowered first to reduce the damage of the drill bit. After the drill bit is submerged in the rock, the air volume should be adjusted to the normal air volume.

3. In the process of using the straight drill bit, if the drill bit has a gap of more than 3mm, or the drill bit has an inverted cone, the drill bit must be removed, polished and repaired, otherwise the working speed will be reduced, and There may be slivers of the drill bit, and in severe cases, the phenomenon of jamming may occur.

4. During the drilling process, if you encounter a steel bar, avoid it in time, and adjust the direction and position of the drilling as much as possible to prevent foreign objects from damaging the drill bit.

5. In the process of rock drilling, if the drill bit occurs, the drill bit must be replaced with a cross-shaped drill bit. or other types of drill bits

6. In the process of rock drilling, if serious wear is found on the straight drill bit, other types of alloy drill bits must be replaced in time.

7. In the rock drilling operation, it is necessary to ensure sufficient water supply to avoid the occurrence of bit wear or jamming and improve the life of the bit.
