The Widin Carbide Corner Radius End Mill for Mold & Die is a precision 4 mm milling tool designed for moldmakers and die machinists who demand clean radii in tight, deep cavities. With a long-neck design, it reaches complex internal features while delivering smooth surface finishes and reliable stability.

• Diameter: 4 mm
• Overall length: 40 mm
• Corner radius: R0.5
• Flutes: 2
• Helix angle: 30°
• Material: Carbide
• Neck design: Long neck/long shank for extended reach and stability in deep grooves
• Application: Ideal for mold and die machining with intricate radii and deep cavities

The 2-flute configuration promotes efficient chip evacuation and delivers a smooth, consistent finish on molded surfaces. The 30° helix minimizes cutting forces, enabling steadier cutting and improved productivity when removing material from challenging geometries. The long-neck design provides extended reach, reducing tool changes and enabling precise radii in deep grooves and tight corners often found in mold and die work. Carbide construction offers excellent wear resistance and edge retention for durable performance across demanding applications.
