What problems can drills have during drilling?

Some of the following problems may occur in the drilling process of the drill bit:

- Excessive wear:

It may be caused by high hardness of the formation, unreasonable drilling parameters, etc.

- Chipping or damage:

May occur when encountering hard foreign objects or when subjected to large impacts.

- Inefficient drilling:

If the drilling speed is slow, it may be due to the drill bit not adapting to the formation, bluntness of the drill bit, etc.

- Drill jamming:

It may be caused by unstable stratum, accumulation of debris, etc.

- Overheating:

Prolonged high-speed drilling may lead to high temperature of the drill bit, affecting its performance and life.

- Unsmooth hole wall:

May cause the hole to be drilled out of specification.

- Drill jitter:

May affect drilling accuracy and stability.

- Drilling direction deviation:

May result in inaccurate drilling position.
