How to determine if the drill bit needs to be replaced
The determination of whether the drill bit needs to be replaced can be analyzed from the following aspects:
1. Drilling speed:
If the drilling speed of the drill bit significantly decreases, or if there are phenomena such as sticking or jumping during the drilling process, it may be due to severe wear and replacement of the drill bit.
2. Drill appearance:
Observe the appearance of the drill bit. If there are obvious signs of wear, cracks, notches, etc. on the surface of the drill bit, or if the cutting edge of the drill bit is no longer sharp, it may need to be replaced.
3. Drilling effect:
If the drilling effect of the drill bit is poor, or the quality of the drilled rock core is poor, it may be due to severe wear and replacement of the drill bit.
4. Drill life:
Determine whether replacement is necessary based on the service life and drilling workload of the drill bit. If the drill bit has reached its service life or the drilling workload has exceeded the design life of the drill bit, it may need to be replaced.
5. Drilling cost:
If the cost of replacing the drill bit is lower than the cost of continuing to use a severely worn drill bit, it may be necessary to replace it.
