Why material is important for drilling teeth?

First of all, the material of the drilling teeth has a great impact on the cost, which is mainly reflected in the following aspects:

1. Raw material cost

The raw material cost of drilling teeth of different materials is significantly different. For example, the raw material cost of cemented carbide drilling teeth is usually higher than that of steel drilling teeth, because the manufacturing process of cemented carbide is more complicated and requires more expensive alloy elements. This directly leads to the relatively high market price of cemented carbide drilling teeth.

2. Manufacturing cost

In addition to the raw material cost, drilling teeth of different materials also differ in manufacturing cost. The manufacturing process of cemented carbide drilling teeth requires high-precision processing equipment and processes to ensure the accuracy and durability of its cutting edge. This increases the manufacturing cost, but also improves the quality and performance of the product. In contrast, the manufacturing cost of steel drilling teeth may be lower, but the durability and cutting efficiency may also be reduced accordingly.

3. Service life and maintenance cost

The material of the drilling teeth also directly affects its service life and maintenance cost. Due to its high hardness and wear resistance, cemented carbide drilling teeth usually have a longer service life, reducing the frequency and maintenance cost of replacing drilling teeth. Steel drilling teeth may need to be replaced after a period of use, thereby increasing maintenance costs.

4. Overall cost-effectiveness

Although carbide drilling teeth have a higher initial investment, they may have a higher overall cost-effectiveness due to their long service life and low maintenance costs. Conversely, steel drilling teeth have a lower initial investment, but may have a lower overall cost-effectiveness due to their short service life and high maintenance costs.

Beside the cost, the material of drilling teeth also has a crucial impact on their performance, which is mainly reflected in the following aspects:

1. Wear resistance

Wear resistance is an important performance indicator of drilling teeth material. drilling teeth of different materials have significant differences in wear resistance.

- Carbide: Carbide drilling teeth usually have high wear resistance and can maintain good cutting edge shape and cutting efficiency during long-term use. This material is suitable for drilling hard formations, such as rocks, gravel layers, etc.

- Steel material: Steel drilling teeth have relatively low wear resistance, but good toughness. This material is suitable for drilling soft formations, such as soil layers, soft rock layers, etc. However, when used in hard formations, the wear rate of steel drilling teeth will be significantly accelerated.

2. Hardness and toughness

Hardness and toughness are two other important performance indicators of drilling teeth materials. They have a direct impact on the cutting efficiency and durability of drilling teeth.

- Hardness: drilling teeth with higher hardness can more effectively break the formation and improve cutting efficiency. However, too high hardness may cause the drilling teeth to have reduced toughness and be easy to break. Therefore, when selecting drilling teeth material, it is necessary to balance the relationship between hardness and toughness.

- Toughness: drilling teeth with good toughness can resist greater impact and vibration, reducing the risk of fracture. However, too high toughness may cause the hardness of the drilling teeth to decrease, affecting cutting efficiency. Therefore, when selecting drilling teeth material, it is also necessary to consider the balance between toughness and hardness.

3. Corrosion resistance

Under some special geological conditions, such as saline formations, acidic formations, etc., drilling teeth may be affected by corrosion. Therefore, corrosion resistance is also an important performance indicator of drilling teeth material.

- Stainless steel material: Stainless steel drilling teeth have good corrosion resistance and can maintain good performance in corrosive environments. However, the hardness and wear resistance of stainless steel may be relatively low, and it needs to be selected according to specific formation conditions.

- Other alloy materials: Some special alloy materials also have good corrosion resistance, and at the same time have high hardness and wear resistance. These materials are suitable for drilling in formations with strong corrosiveness.

4. Cost and maintenance

The material of the drilling teeth also directly affects its cost and maintenance costs.

- High-end materials: The cost of drilling teeth made of high-end materials such as cemented carbide is higher, but the service life is long and the maintenance cost is relatively low. This type of drilling teeth is suitable for engineering projects with high requirements for construction quality.

- Low-end and medium-end materials: The cost of drilling teeth made of low-end and medium-end materials such as steel is lower, but the service life may be shorter and require frequent replacement and maintenance. This type of drilling teeth is suitable for engineering projects with low requirements for construction quality or temporary replacement.
