Description
The Widin Carbide Corner Radius End Mill is a versatile 4-flute carbide cutting tool designed for mold and die machining. It features a 16 mm diameter, 100 mm overall length, and a corner radius of R0.5, enabling precise corners and smooth contours on complex molds.
Built for varied materials and applications, this end mill delivers easy machinability, efficient chip evacuation, and high-quality surface finishes. Its multi‑purpose design and optimized geometry help you tackle demanding mold and die tasks with confidence and consistency.
- Corner radius options (including R0.5): Provides the right radii to match mold and die features, enabling precise fillets and smoother surfaces with minimal secondary finishing.
- 4-flute carbide design for efficient cutting: Four cutting edges share the load for faster material removal, better chip evacuation, and stable cutting that supports clean, consistent finishes.
- Variable index geometry for consistent performance: Reduces vibration and chatter, helping maintain edge quality across different materials and feeds for reliable tool life.
In practice, this end mill helps you streamline mold and die workflows by delivering accurate geometry, efficient material removal, and repeatable surface quality. The combination of carbide hardness, multiple flutes, and thoughtfully engineered geometry translates to lower downtime, fewer tool changes, and dependable results that you can trust on every job.
