Description
The Widin Carbide End Mill is a precision finishing tool designed for mold and die work. With a 4 mm diameter, a 4-flute configuration, and a tapered neck, it delivers stable, accurate cuts with efficient chip evacuation, making it ideal for finishing tight cavities and achieving smooth surfaces. Engineered to machine high-hardened materials up to HRc70, it pairs a newly developed raw material with an ALTiN+HH coating to deliver reliable performance in dry and high-speed cutting.
- 4‑Flute Finishing Geometry: Optimized for mold and die finishing, it delivers refined surface quality with efficient chip evacuation to reduce secondary passes.
- Tapered Neck for Stability: The tapered neck design provides enhanced stability and minimizes deflection, helping maintain tight tolerances in deep or complex pockets.
- Durable ALTiN+HH Coating for Tough Materials: Combined with a high-hardness substrate, it enables cutting hard materials up to HRc70 and supports dry, high-speed operation for longer life and consistent performance.
This combination of geometry, stability, and coating means faster cycle times, fewer tool changes, and repeatable results across mold and die projects—from fine finishing passes to precision contouring—so you can trust the outcome of every cut.
