The Widin Carbide Corner Radius End Mill for Mold & Die is a precision cutting tool built for serious mold and die work. With a 4-flute configuration and a tapered neck, it delivers smoother cutting action and improved surface finishes across challenging materials and complex cavities.

Designed for engineers, machinists, and makers who demand reliable, repeatable results, this end mill’s tapered effective length increases rigidity and stability, making it well-suited for deep groove milling. It’s available in multiple specifications to match your exact machining needs, delivering precise results and extended tool life when working on molds or dies.

• Tapered neck design for greater rigidity: The tapered neck increases rigidity and stability, reducing deflection and chatter during deep groove milling for cleaner, more accurate cuts.
• Four-flute geometry for smoother cuts: Four flutes share the cutting load for efficient material removal, helping minimize vibrations and produce smoother surface finishes.
• R0.1 corner radius with carbide durability: The precise corner radius creates clean fillets in mold features while carbide construction delivers longer tool life and better wear resistance.

With its combination of rigidity, smooth cutting action, and precise corner geometry, this end mill helps you achieve repeatable tolerances and high-quality finishes in mold and die work. The robust carbide design supports longer production runs, reduces downtime from tool changes, and provides dependable performance across demanding applications—making it a trusted choice for both professional shops and dedicated hobbyists.
