Description
The Widin Carbide End Mill is a 3-flute ball nose finishing tool designed for mold and die work. With a 4 mm diameter and 50 mm overall length, it features a stub-cut body and an extended neck to maximize rigidity during contouring in tight cavities. This design helps you achieve precise, repeatable finishes in complex mold geometries.
The ALTiN+HH coating reduces friction and promotes smooth chip evacuation, enabling efficient dry cutting and high-speed operation. Built to withstand high-hardness materials up to HRc70, this end mill delivers long tool life and stable performance even in challenging finishing tasks.
- Rigid, extended-neck design: Improves stiffness and minimizes tool deflection in deep cavities, delivering consistent, accurate surface finishes with fewer passes.
- Low-friction ALTiN+HH coating: Minimizes heat and wear while improving chip evacuation, helping you maintain cutting speeds and extend tool life in dry or high-speed cutting.
- Hard-material capability up to HRc70: Ready for tough steels and alloy workpieces, offering reliable finishing performance without frequent tool changes.
The end mill's combination of precise geometry, robust coating, and high-hardness capability translates into cleaner surfaces, tighter tolerances, and reduced downtime in mold and die finishing workflows. Whether you're refining cavities, facets, or contours, this tool helps you achieve higher quality results with fewer reworks and longer interval maintenance.
