High-hardness milling cutters and high-performance milling cutters are two different types of cutting tools. They have obvious differences in materials, manufacturing 

processes, performance and scope of application. The following is a detailed comparison of the two types of milling cutters.

1. Materials and manufacturing processes

1. High-hardness milling cutters: Usually made of high-hardness materials, such as cemented carbide, ceramics, etc. These materials have extremely high hardness and wear 

resistance, and can maintain good cutting performance under high temperature and high pressure. The manufacturing process of high-hardness milling cutters is relatively 

simple, mainly made through processes such as powder metallurgy, pressing and sintering.

2. High-performance milling cutters: Made of high-performance materials, such as high-speed steel, super-hard alloy, etc. These materials not only have high hardness and 

wear resistance, but also have good toughness, impact resistance and heat resistance. The manufacturing process of high-performance milling cutters is more complicated, 

including precision casting, heat treatment, precision grinding and other processes.

2. Performance

1. Cutting efficiency: High-performance milling cutters usually have higher cutting efficiency than high-hardness milling cutters due to the use of high-performance materials 

and advanced manufacturing processes. High-performance milling cutters can remove materials faster during the cutting process and improve processing efficiency.

2. Cutting accuracy: The cutting accuracy of high-performance milling cutters is also higher than that of high-hardness milling cutters. High-performance milling cutters have 

higher manufacturing accuracy and sharper cutting edges, which can reduce the impact of cutting force and cutting heat on the workpiece, thereby improving processing 

accuracy.

3. Tool life: High-performance milling cutters have a longer service life. Due to their excellent wear resistance and impact resistance, high-performance milling cutters can 

maintain good cutting performance during the cutting process and reduce the possibility of tool wear and breakage.

4. Scope of application: High-hardness milling cutters are mainly used for processing materials with higher hardness, such as hardened steel, cast iron, etc. High-performance 

milling cutters are suitable for processing various materials, including materials with higher hardness and difficult-to-process materials, such as titanium alloys, 

high-temperature alloys, etc.

III. Summary

In summary, there are obvious differences between high-hardness milling cutters and high-performance milling cutters in terms of materials, manufacturing processes, 

performance and scope of application. High-hardness milling cutters are mainly characterized by high hardness and wear resistance, and are suitable for processing materials 

with higher hardness; high-performance milling cutters have higher cutting efficiency, cutting accuracy and service life, and are suitable for processing various materials. 

In practical applications, the appropriate milling cutter type should be selected according to the processing requirements and workpiece materials.

IV. Selection and application suggestions

1. Select according to the workpiece material: When processing materials with higher hardness, high-hardness milling cutters can be preferred; and for the processing of a 

variety of materials, high-performance milling cutters have more general applicability.

2. Consider processing requirements: If there are high requirements for processing efficiency, accuracy and tool life, high-performance milling cutters should be selected.

3. Economic benefit evaluation: The price of high-performance milling cutters is usually higher than that of high-hardness milling cutters, but in long-term use, due to their 

higher cutting efficiency and service life, the overall cost can be reduced. Therefore, the initial investment and long-term use costs should be comprehensively considered 

when choosing.

4. Technical support and service: Choosing a branded milling cutter manufacturer can obtain better technical support and after-sales service to ensure the smooth progress 

of the processing process.

In short, when choosing high-hardness milling cutters and high-performance milling cutters, multiple factors such as workpiece material, processing requirements, economic 

benefits and technical support should be considered comprehensively to ensure that the selected milling cutter type can meet actual processing requirements and improve 

production efficiency.
