Engineered for precision mold and die work, the Widin Carbide Corner Radius End Mill delivers clean corner radii and smooth surface finishes in tight cavities. With a 4 mm cutting diameter and a long-neck design, it provides extended reach for deep molds and intricate features.

• Diameter: 4 mm cutting diameter for precise corner work
• Corner Radius: R0.5 to create durable, accurate fillets
• Overall Length: 30 mm, paired with a long neck for extended reach
• Flutes: 2 flutes for efficient cutting and reliable chip evacuation
• Helix Angle: 30° for smooth cutting action and reduced load
• Material: Carbide for enhanced hardness, wear resistance, and stable performance
• Shank/Design: Long neck (long shank) construction for deep groove machining
• Applications: Ideal for mold & die profiling, pocket finishing, and precision corner work

This end mill is designed to maintain precise dimensions and a consistent finish across complex mold and die geometries. The combination of a compact 4 mm diameter, a 0.5 mm corner radius, and a 30° helix angle helps balance material removal with surface quality, while the long-neck geometry unlocks deeper cavities without sacrificing rigidity. Whether you’re finishing tight fillets or sculpting intricate profiles, this tool supports reliable, repeatable results with minimal tool deflection and steady feeds.
