1. **High hardness and wear resistance**
Carbide is made of materials such as tungsten carbide and cobalt. It has high hardness and strong wear resistance. It can effectively cope with the hole opening needs of various materials such as metal, wood, plastic, etc., and prolong the service life.
2. **Efficient cutting**
Its sharp cutting edge and reasonable geometric design improve cutting efficiency and reduce processing time, especially suitable for large-scale operations.
3. **High temperature resistance**
Carbide can still maintain good performance at high temperatures, suitable for high-speed cutting and long-term operation, and reduce wear or deformation caused by high temperature.
4. **High precision**
The excellent manufacturing process ensures that the hole opener is accurate in size and is suitable for occasions with strict requirements on hole diameter, such as mechanical processing and electronic manufacturing.
5. **Versatility**
Applicable to a variety of materials, reducing the frequency of tool replacement and improving work efficiency.
