The Widin Carbide Corner Radius End Mill is a precision cutting tool designed for mold and die applications. With a 3 mm diameter and a 16 mm cutting length, it features a 0.2 mm corner radius to create clean internal corners while protecting workpiece integrity. The four-flute design and tapered neck work together to reduce chatter and deliver smoother, more consistent cuts.

Engineered for rigidity, the tapered effective length boosts stability during deep groove machining, helping maintain tight tolerances even in challenging materials. Available in multiple specifications to match your exact project requirements, this end mill delivers precise results and longer tool life when shaping molds, dies, and complex cavities.

• Four-flute design for smooth, consistent cuts: The 4-flute configuration provides efficient chip evacuation and stable cutting action, delivering consistent surface finishes and longer tool life in mold materials.
• Tapered neck for greater rigidity: The tapered neck increases stiffness during deep groove and long-reach milling, reducing deflection and improving dimensional accuracy.
• Corner radius R0.2 for clean corners: The corner radius preserves part geometry in mold and die work, minimizes edge chipping, and yields smoother surfaces on corners and pockets.

With this end mill, you gain reliable performance across demanding milling tasks, improved surface quality, and extended tool life. The combination of rigidity, controlled chatter, and precise corner radii supports faster cycles, less rework, and more consistent results across a range of materials and mold/die geometries.
