HRC 60 Tungsten Carbide Endmills for Steel Cutting

Tungsten Carbide End Mill 

Tungsten carbide milling cutters (commonly known as tungsten steel milling cutters) are the "main force" of CNC machining centers. They are made of tungsten carbide as the base material. Due to their high hardness, high wear resistance and high temperature resistance (about 800℃), they completely outperform traditional high-speed steel cutting tools in terms of efficiency.

Tool Body Hardness: 

The cemented carbide substrate has extremely high hardness (approximately HRA 89–93, equivalent to approximately HRC 70–80). “HRC 60 milling cutters” available on the market typically refer to tools that have undergone special heat treatment or feature a specific substrate formulation, with an overall flexural strength suitable for cutting under high-hardness conditions (HRC 60), making them less prone to chipping.

Upper Machining Limit: These tools are typically paired with coatings such as TiAlN (titanium aluminum nitride) and are claimed to be capable of directly machining quenched mold steel and tool steel with hardness ranging from HRC 50 to 60.

HRC 60 tungsten carbide endmill Applications: Specially Designed for Tackling Tough Challenges

These milling cutters are indispensable tools in mold manufacturing and precision machining, primarily used in the following demanding applications:

Important Note: This tool is not suitable for machining soft metals such as aluminum and copper. Soft materials can cause tool sticking (chip buildup), leading to poor chip evacuation and accelerated tool wear.
