Carbide end mills are one of the core cutting tools in CNC machining, renowned for their high hardness, wear resistance, and high-temperature resistance. Compared to high-speed steel (HSS) tools, carbide end mills have a longer service life, can withstand higher cutting speeds, and significantly improve machining efficiency. Their excellent rigidity makes them suitable for high-precision machining, particularly in difficult-to-machine materials such as stainless steel, titanium alloys, and hardened steel.

Performance Features  

High Hardness: The hardness of carbide (tungsten-cobalt or tungsten-titanium alloys) can reach HRA90 or higher, making it suitable for high-speed cutting.

Heat Resistance: Maintains performance at temperatures above 800°C, reducing the risk of thermal deformation.  

Multi-Flute Design: 2-flute to 6-flute structures balance cutting efficiency and surface finish; 4-flute milling cutters are commonly used for finishing operations.  

Application Scenarios  

Mould Manufacturing: Precision cavity machining.  

Aerospace: Cutting of high-strength alloy components.  

Automotive Parts: Mass production of high-hardness materials.  

Notes

Select appropriate coatings: TiAlN coatings are suitable for high-temperature machining, while DLC coatings are suitable for non-ferrous metals.

Coolant usage: Internal cooling design is recommended when machining heat-resistant alloys.

Parameter optimisation: Avoid excessive cutting depths to prevent edge chipping; refer to the manufacturer's recommended cutting parameters.

Carbide milling cutters, optimised for both machining efficiency and precision, have become an indispensable tool in modern CNC machining.
