We do not make carbide end mills from a solid material. We make carbide end mills from carbide material, usually a composite material produced by powder metallurgy technology. It has a matrix composed of tungsten carbide and cobalt carbide. The main components of carbide include hard particles and bonding agent. These two materials can improve the high hardness, wear resistance, and toughness of the tool.

What are the applications of Hard alloy end mills?
What are the advantages of carbide end cutter compared to other cutting tools?
Performance characteristics of carbide end mills:
We widely use Hard alloy end mills in machining scenarios in various industries because of their high hardness, wear resistance, and versatility. The following are the main performance characteristics of carbide end cutter:
1. High hardness: the hardness of carbide end cutter can be as high as 90HRA or more. This allows Hard alloy end mills to easily machine materials with high hardness, such as abrasive steel, stainless steel, titanium alloys and other materials
2. Wear resistance: suitable for machining high hardness and high strength materials, the main component of tungsten carbide is tungsten carbide, which has extremely high wear resistance and can remain sharp in the high-speed cutting and continuous machining of carbide end cutter.
3. High temperature resistance: carbide end mills can cut at temperatures as high as 800-1000 ℃, suitable for high-speed cutting, even in dry cutting or insufficient lubrication conditions, can maintain good cutting performance, reduce the risk of tool passivation
4. Impact resistance: although the hardness of the carbide end mill is high, but the toughness is quite low, it is easy to crumble under severe impact, combined with the toughness of cobalt and other metals, can withstand a certain impact.
Recommended end mill models for high speed steel (HSS) machining:
When machining HSS, we recommend applying end mill models with high hardness, wear resistance and good toughness.
For example: PUWEI Flat End Mills: suitable for flat surface machining, groove machining, side milling. Recommended 4-flute flat end mills: suitable for side milling and groove milling of HSS, balancing material removal efficiency and surface quality.
