The Widin Carbide Corner Radius End Mill is a precision cutting tool designed for mold and die work. With its 4-flute configuration and a tapered neck, it minimizes chatter and delivers smoother cuts, resulting in improved surface finishes. Its 4 mm diameter, 50 mm overall length, and corner radius of 0.3 mm support deep groove machining while maintaining consistent rigidity. Available in multiple specifications to match different depths and effective lengths, this end mill adapts to diverse machining tasks without compromising performance.

• Rigid, stable cutting with a tapered neck: The tapered neck enhances rigidity at depth, reducing deflection during long reach cuts and enabling precise, consistent material removal in deep grooves.
• Smaller chatter, better finishes: Four flutes and optimized geometry work together to damp vibrations, providing smoother cuts and cleaner surfaces with fewer finishing passes.
• Corner radius for mold & die accuracy: The 0.3 mm corner radius delivers controlled radii and sharp, repeatable features in molds and dies while promoting longer tool life and reliable performance.

Designed for engineers, machinists, and shop floors alike, this end mill combines dependable carbide durability with practical geometry to support high-precision mold and die work. Its balanced rigidity, chatter reduction, and consistent corner detail help you complete intricate features faster, reduce rework, and extend tool life—delivering reliable results across a range of challenging materials and applications.
