The disadvantages of DTH hammer Bits, or Down the Hole Hammer Bits, may include the following:

1. quicker wear and tear:

When used in hard formations, they tend to wear out and require frequent replacement.

2. Higher cost:

Manufacturing and maintenance costs are relatively high.

3. Higher geological requirements:

In some complex geological conditions, drilling results may be unsatisfactory.

4. Easily damaged:

Subject to shock and vibration, failure may occur.

5. Limited adaptability:

May not be applicable to all types of strata.

6. High technical requirements:

Operation and maintenance require some specialized knowledge and experience.

7. Difficult to maintain:

Maintenance may be difficult in complex working environments. 

8. Restricted drilling speeds:

In some cases, drilling speeds may not be as fast as other types of drills.

However, submerged hammer drills have many advantages and can work well under the right conditions.
