Widin Carbide Corner Radius End Mill For Mold & Die - Variable Index 4 Flute - 4mmx R0.3

Widin Carbide Corner Radius End Mill for Mold & Die — 4 mm diameter with a 0.3 mm corner radius, built for precision in mold and die applications. The long shank design provides extended reach for deep grooves and tight pockets, helping you access demanding features without compromising rigidity.

Featuring a variable index geometry with four flutes, this end mill delivers smoother cutting, lower cutting forces, and efficient chip evacuation. The result is more consistent corner radii, cleaner finishes, and less vibration during heavy material removal, even in challenging workpieces.

• Variable index geometry: Distributes cutting edges to balance loads, reduce vibration, and improve chip evacuation for smoother, more efficient machining.
• 4-flute design for rigidity and chip clearance: Provides strong cutting performance with effective debris removal to maintain stable feeds and a high-quality surface finish.
• Long shank for deep grooves and hard‑to‑reach features: Delivers extended reach into deep pockets and tight cavities while preserving rigidity for precise, repeatable results.

This end mill helps you streamline mold and die workflows by delivering repeatable radii, consistent finishes, and reliable performance across a range of materials. With its carbide composition and optimized geometry, you can reduce downtime, improve tool life, and tackle complex features with confidence, from deep grooves to tight radii, all while maintaining accuracy and surface quality.
