High feed 4-flute milling cutter
The HF492 series end mills combine strength and superior performance. These U-groove end mills are designed to extend tool life in alloy steels, carbon steels, tool steels, and hardened steels up to 45HRc. Advanced grinding processes ensure cutting stability, and a small clearance angle design maximizes edge strength in both roughing and finishing applications. The HF492 end mill is developed for precision machined parts. Featuring an eccentric clearance function for maximum edge strength and a TIX-18 coating for enhanced performance in hard materials, it is an excellent choice for a wide range of applications.

Design details engineered for accuracy, tool life and process stability.
The substrate hardness reaches HRC65, combining high hardness with excellent impact resistance, resulting in a tool life 2-3 times that of ordinary end mills.
Withstands high temperatures up to 1200°C, with a surface hardness of HV3200, maintaining excellent wear resistance even under high-speed cutting, reducing the risk of coating peeling.
The cutting edge radius is controlled within 0.015mm, balancing edge sharpness and chipping resistance, suitable for precision contour machining.
Variable helical end mills reduce chatter and vibration, improving the finishing quality and dimensional accuracy of U-beams, as U-beams typically bear structural loads and require precise specifications.
End milling can cut various shapes and contours on U-beams, allowing machinists to machine complex geometries such as slots or grooves within the beam structure.
Employing an eccentric removal design, maximum edge strength is achieved in both roughing and finishing applications.
