Meet the Widin Carbide Corner Radius End Mill for Mold & Die — a precision tool designed for mold and die work where clean corners and reliable finishes matter. With a 4 mm diameter, 30 mm length, and a 0.2 mm corner radius (R0.2), this 2-flute end mill features a long-neck design to reach into tight cavities while maintaining rigidity.

• Diameter: 4 mm — a precise size for tight pockets and fine detail in small mold components.
• Corner Radius: R0.2 (0.2 mm) to preserve flank strength and enable smooth, accurate corners.
• Flutes: 2-flute geometry designed for rigidity and effective material removal.
• Helix Angle: 30° for balanced cutting forces and reliable chip evacuation.
• Neck/Reach: Long-neck design provides extended reach for deep grooves and hard-to-access features.
• Material: Solid carbide construction delivers wear resistance and stable performance in mold steels and other alloys.
• Application: Specifically engineered for mold and die milling, including cavity finishing and intricate geometry.

With this geometry and carbide composition, you can expect clean corners, smooth surface finishes, and reliable material removal in mold and die projects. The corner radius minimizes stress concentration and helps extend edge life on cavity walls, while the long-neck reach reduces tool changes when working in deep channels or near walls. Use a steady feed and appropriate coolant to maximize tool life and surface quality in mold steels and non-ferrous alloys.
