how to choose between hard alloy and high-speed steel?

2025-08-25

In fields such as automotive styling, industrial design, and mold development, a double-edged oil mud knife is an essential sampling tool. For designers and machinists, the material of the cutting tool determines the quality and durability of surface finishing. So, when it comes to material selection for AMG double-edged clay knives, should hard alloy or high-speed steel be given priority? This article will provide you with a detailed analysis to help you find the most suitable solution.


Advantages of Hard Alloy Mud Knife

Hard alloy clay knives are known for their high hardness and wear resistance, making them suitable for long-term, high-intensity sampling work. It can maintain a sharp cutting edge, smooth cutting, and high surface smoothness when carving oil mud, wax materials, and plastic prototype materials. For automotive styling and industrial design models that require extensive finishing and complex surface polishing, hard alloy cutting tools can significantly improve efficiency and reduce tool replacement frequency.


Application scenarios of high-speed steel oil mud knife
Compared with hard alloys, high-speed steel oil mud knives have better toughness and stronger impact resistance, making them suitable for daily sampling and low to medium strength finishing tasks. Its price is more advantageous, suitable for laboratories, design studios, and cost sensitive projects. In some small-scale and rapidly iterating mold development processes, high-speed steel oil mud knives can provide a more cost-effective option.


How to choose the appropriate material?
If you pursue durability and high efficiency, we recommend choosing a hard alloy oil mud knife. It is suitable for CNC engraving machines and large-area finishing tasks.
If you value flexibility and economy, high-speed steel oil mud knives are more suitable, especially for manual polishing and short cycle projects.
AMG also supports customization of various rounded corners such as R5~R15, ensuring that the cutting tools are compatible with different surfaces and meet the diverse needs of automotive styling and industrial models.



FAQ

Q: Is the cemented carbide oil mud knife more durable?
A: Yes, hard alloys have better wear resistance and are suitable for high-frequency processing.
Q: Is the high-speed steel oil mud knife suitable for carving machines?
A: Sure, but more suitable for low-speed, light load CNC equipment or handheld grinders.
Q: Can AMG clay knives be used for metal cutting?
A: Not recommended. This product mainly targets oil sludge, wax materials, and plastic prototype materials.
