The Widin Carbide Corner Radius End Mill is a precision cutting tool designed for mold and die work. With a 3 mm diameter, 50 mm length, and a corner radius of R0.2, this 4-flute end mill delivers reliable performance for precise radii and clean, consistent holes and grooves.

Designed for engineers, machinists, buyers, and hobbyists alike, it enables smooth cutting operations, improved surface finishes, and longer tool life—even when working on deep, challenging grooves or tight corners.

• 4-Flute carbide design: Ensures efficient chip evacuation and smoother cutting, reducing chatter for better surface finish and more predictable tool life.
• Tapered neck for rigidity: The tapered effective length increases stiffness and stability, making it ideal for deep groove machining and precise corner radii.
• Corner radius R0.2 with versatile specs: Offers a reliable, consistent corner finish and the flexibility of choosing from various specifications to match your machining needs.

Together, these features translate to more confident setups, faster cycle times, and consistently high-quality results on molds and dies. The tool’s rigidity and controlled cutting dynamics help you achieve accurate corners, reduce rework, and extend overall tool life—supporting smoother workflows and reliable performance across demanding applications.
