The Widin Carbide Corner Radius End Mill for Mold & Die is a precision cutting tool designed for mold-making and die work. With a 3 mm diameter, 70 mm overall length, and a 0.5 mm corner radius, this 4-flute end mill delivers smooth, controlled cuts and accurate edges. Its tapered neck and carbide construction help suppress chatter and improve surface finishes, even in high-strength materials.

Available in multiple effective-length specifications, this end mill lets you choose the right reach for your project—whether you’re profiling shallow features or machining deep grooves. The tapered neck increases rigidity and stability, providing dependable performance throughout the cut and helping extend tool life in demanding mold and die applications.

• 4-flute carbide design: Ensures efficient chip evacuation and smoother cuts, delivering a smooth surface finish on mold and die surfaces.
• Tapered neck for enhanced rigidity: Adds stiffness to the cutting portion, reducing vibration and chatter during deep groove machining for cleaner, more accurate profiles.
• Corner radius of 0.5 mm (R0.5): Maintains precise, durable corners in molds and dies while resisting wear for longer tool life.

With this combination of geometry and rigidity, you’ll achieve consistent, high-quality results across multi-pass milling, reduced downtime from fewer tool changes, and longer tool life in challenging materials. The Widin end mill helps you finish complex mold and die cavities with better edge definition and smoother surfaces, making it a reliable workhorse for professional shops, job shops, and serious hobbyists alike.
