The Widin Carbide Corner Radius End Mill is a precision cutting tool designed for mold and die work, featuring a 4‑flute design and a tapered neck that excels at machining sloped surfaces and varying taper angles for clean, accurate results on complex geometries. The tapered neck boosts stability and rigidity, helping maintain tight tolerances and smooth finishes, while a small corner radius (R0.3) supports consistent fillets and reduces stress on critical features. With four flutes, it also delivers efficient chip evacuation for steady cutting and reliable material removal.

• Tapered neck for stability on sloped surfaces: The tapered geometry increases rigidity where it matters, reducing deflection and improving accuracy when cutting inclined profiles and complex molds.
• Four-flute design for efficient cutting and chip evacuation: More flutes mean quicker material removal, cleaner surfaces, and reduced chip buildup, enhancing tool life and uptime.
• Corner radius R0.3 for controlled fillets and durable finishes: The precise small radius preserves wall strength while enabling smooth fillets and reliable transitions, lowering the risk of edge chipping on delicate features.

Whether you’re tackling tight tolerances, intricate geometries, or delicate corners, this end mill helps you complete projects faster with fewer passes and less rework. The combination of a tapered neck, 4‑flute geometry, and the exact R0.3 corner radius delivers reliable performance across mold and die applications, supporting consistent finishes, longer tool life, and smoother CNC workflows.
