Designed for mold and die manufacturing, the Widin Carbide Corner Radius End Mill delivers precise internal corners and dependable tool life. With a 3 mm diameter and a 0.3 mm corner radius in a 4-flute carbide design, it provides repeatable radii and solid performance for demanding milling tasks.

Built with variable index geometry, it distributes cutting edges to reduce cutting forces and improve chip evacuation, helping you achieve smoother finishes and more efficient machining. The long shank offers extended reach for deep groove milling, enabling access to tight pockets and tall features without repositioning.

• Variable index, 4-flute design: Optimizes edge distribution to lower cutting forces and enhance chip evacuation, delivering smoother cuts and consistent results across challenging mold and die features.
• Corner radius versatility (R0.3): Provides precise radii control for tight corners and smooth wall finishes, with a broad range of radii available to match complex mold geometries, including R0.3.
• Long shank for deep groove machining: Extended reach allows you to mill deep channels and cavities without frequent tool changes, maintaining rigidity and reducing setup time.

In practice, this end mill helps you shorten cycle times, improve surface finish, and maintain reliable performance under demanding cutting conditions. Its carbide construction resists wear in mold and die environments, while the combination of variable index geometry, precise corner radii, and extended reach supports consistent, high-quality results across a variety of materials and applications.
