Description
The Widin Carbide End Mill is a precision finishing tool designed for mold and die work. Featuring a 3-flute ball nose and a stub-cut length, it delivers steady, accurate passes in tight pockets and deep cavities. With a 3mm diameter and 50mm length, it’s built for reliable, controlled finishing where detail and consistency matter.
Equipped with an ALTiN+HH coating, this end mill reduces friction and enhances chip evacuation, enabling dry and high-speed cutting. It’s engineered to handle hardened materials up to HRc70, delivering durable wear resistance and long tool life even in demanding finishing tasks.
- Rigid stub-cut design with extended neck: Improves rigidity and stability during finishing passes, reducing deflection and chatter for consistent surface quality.
- ALTiN+HH coating for wear resistance and easy chip evacuation: Lowers friction, improves heat management, and supports efficient dry/high-speed cutting to extend tool life.
- Suitable for hardened materials up to HRc70: Built to withstand tough mold/die steels, delivering reliable performance in challenging finishing applications.
Whether you’re finishing mold cavities, refining die surfaces, or smoothing complex contours, this end mill delivers consistent, high-quality finishes with fewer passes. The combination of a rigid stub-cut design, extended neck, and advanced coating helps you maintain tight tolerances, reduce downtime, and achieve repeatable results across parts.
