The Widin Carbide Corner Radius End Mill for Mold & Die is a precision cutting tool designed for moldmakers, die shops, and CNC operators who demand reliable performance and clean, accurate corners. It features a 4 mm diameter, 50 mm overall length, a 0.5 mm corner radius, and a 2-flute configuration, making it well-suited for pocketing, contouring, and deep groove machining in mold and die work.

The tapered neck enhances stability and rigidity along the cut, helping to minimize deflection and chatter during deep groove operations, while the carbide construction delivers wear resistance for longer tool life and consistent results.

• Corner Radius for Smooth Edges: The 0.5 mm radius helps maintain smooth, accurate corners in cavities and reduces edge chipping, improving part finish and reducing post-processing.
• Tapered Neck for Stability in Deep Grooves: The tapered neck increases rigidity along the cutting length, minimizing deflection and vibration in long-reach or deep-pocket operations for more consistent dimensions.
• 2-Flute Carbide Design for Efficient Cutting: Two flutes provide efficient chip evacuation and a balanced cutting action, delivering reliable finishes across a range of mold and die materials with good surface quality.

With this end mill, you gain predictable performance, longer tool life, and smoother workflows in mold and die production. The combination of a precise corner radius, tapered neck, and carbide substrate helps you achieve cleaner pockets, sharper corners, and repeatable results—reducing rework, speeding up cycles, and improving overall part quality.
