The Widin Carbide Corner Radius End Mill is a 4 mm diameter cutting tool designed for precise mold and die work. With a 1 mm corner radius and a 30° helix, it delivers smooth finishes and deep-reach capability for intricate features.

• Diameter: 4 mm
• Overall length: 45 mm
• Corner radius: R1 (1 mm)
• Flutes: 2
• Helix angle: 30°
• Shank/neck design: Long neck for deep groove access and stability
• Material: Carbide
• Primary application: Mold and die machining, precision pocketing and contouring

The 2-flute geometry minimizes cutting forces, enabling efficient material removal and a clean surface finish on mold features. A 30° helix enhances chip evacuation and reduces cutting load, supporting steadier feeds and better productivity in demanding profiles. The long neck design provides extended reach for deep grooves, radii, and tight pockets without sacrificing rigidity. Constructed from carbide, this end mill offers wear resistance and long tool life under typical milling speeds common in mold and die workflows. This tool is ideal for finishing complex cavities, corner radii, and precise contours that define high-precision molds and dies.
