The Widin Carbide Corner Radius End Mill is a precision 5.5 mm diameter, four-flute carbide tool designed for mold and die manufacturing. With a corner radius of R0.2 and a long shank, it delivers reliable performance for contouring, pocketing, and deep-feature milling where reach matters.

Its innovative variable index geometry optimizes cutting edge distribution, reducing cutting forces and improving chip evacuation. The result is smoother machining and more efficient material removal across demanding mold-and-die applications.

• Variable-Index 4‑Flute Design: Balances cutting loads across the flutes to minimize vibration and chatter, helping you achieve consistent finishes and more predictable tool life on complex mold contours.
• Corner Radius Range (R0.2): Provides a flexible set of corner radii to match intricate mold features, enabling precise corners and reliable geometry across passes without retooling.
• Long Shank for Deep Grooves: Extended reach and stable performance for deep slots and hard-to-reach features, while the four flutes maintain efficient, steady material removal.

Engineered for reliability in mold and die milling, this end mill combines a precise 5.5 mm diameter with a 0.2 mm corner radius and a long shank to tackle deep cavities and tight corners. Its variable-index design, efficient chip evacuation, and extended reach work together to streamline workflows, reduce downtime, and deliver consistent, high-quality finishes across production runs and prototypes.
