This versatile end mill is designed to tackle challenging machining tasks with ease. Equipped with a tapered neck, it provides reduced tool vibration and minimized chattering, ensuring smooth and stable cutting operations. This feature makes it particularly suitable for deep grooves and sloped surfaces with various neck specifications, allowing for precise and accurate machining. The effective neck length, following the rake angle, enables the end mill to be applied to various machining scenarios, providing flexibility and adaptability. Designed to handle high hardened materials up to HRc70, this end mill is engineered to withstand demanding machining environments. Its newly developed raw material and coating enhance its performance, making it suitable for dry cutting and high-speed cutting applications.
