The Widin Carbide Corner Radius End Mill is a precision cutting tool engineered for mold and die work. Its 4 mm diameter, extended reach, and R1 corner radius deliver clean, accurate finishes in tight cavities.

• Diameter: 4 mm
• Length/Reach: 20 mm long neck for deep grooves and intricate features in molds and dies
• Flutes: 2-flute design for efficient material removal and smooth surface finishes
• Corner Radius: R1 corner radius to preserve part geometry and reduce edge stress
• Helix Angle: 30° helix for improved chip evacuation and balanced cutting forces
• Material: Carbide for high rigidity and long tool life in demanding milling tasks
• Application: Optimized for mold and die milling, including detailed cavities and tight radii

This end mill helps you achieve precise radii and smooth surfaces with fewer passes, while its long neck provides access to deep pockets and complex contours without sacrificing stability. The combination of a two-flute geometry and a 30° helix reduces cutting load, making it well-suited for mold and die materials and enabling consistent finish across challenging features.
