The Widin Carbide Corner Radius End Mill is a 10 mm diameter carbide milling tool with a 0.3 mm corner radius (R0.3). It combines a 4-flute design with variable-index geometry to handle complex mold and die features with steady, predictable performance. This configuration helps create precise corner radii and smooth transitions in cavities and pockets while maintaining good chip control.

With a long shank, it reaches into deep grooves and extended pockets where space is tight, while the 4-flute arrangement keeps material removal steady and controlled. The combination of variable index and carbide rigidity delivers reliable results even in demanding mold-and-die applications.

• Variable index geometry for smoother cuts: Distributes cutting edges to reduce cutting forces and improve chip evacuation, delivering cleaner finishes and more consistent tool life.
• Precise R0.3 corner radius for reliable fillets: Provides accurate corner radii on mold/die features, reducing post-machining deburring and ensuring consistent part geometry.
• Long shank for deep groove access: Extended reach enables milling of deep pockets and grooves without repositioning, improving workflow and reducing setup time.

Together, this end mill offers precise radii, efficient material removal, and extended reach to streamline mold and die machining. It helps you achieve repeatable, high-quality finishes, shorten cycle times, and maintain dependable performance across demanding applications.
