Widin Carbide Corner Radius End Mill for Mold & Die is a 4-flute carbide tool designed for mold and die manufacturing. It features a 4 mm diameter with corner radii options including R1, giving you flexibility to match every contour, pocket, or edge. The variable-index geometry enhances machinability, reduces cutting forces, and improves chip evacuation for smoother, more efficient milling in demanding applications.

• Variable-index 4‑flute geometry: Delivers smoother cutting action, reduces cutting forces, and improves chip evacuation for steadier performance across complex mold cavities.
• Long shank for deep grooves: Provides extended reach and rigid guidance for deep pocketing and long toolpaths without sacrificing rigidity.
• Wide range of corner radii including R1: Lets you select the exact corner radius to match part geometry, improving edge quality and reducing manual finishing time.

With its variable-index design and long-shank configuration, this end mill helps you achieve consistent edge quality and accurate radii on mold and die components, while reducing cycle times through better chip evacuation and smoother toolpaths. The robust carbide construction delivers reliable performance across demanding materials and repeated use, letting you complete complex contours and pockets with fewer passes and less downtime. In daily shop operations, you gain faster setup, predictable results, and the confidence that your mold and die work will meet tight tolerances and finish requirements.
