Widin Carbide Corner Radius End Mill For Mold & Die - Variable Index 4 Flute - 4mmx 20mm X R0.2 is a high-performance carbide end mill designed specifically for mold and die machining. Its variable index geometry distributes the cutting load across the flutes, promoting smooth chip evacuation and improved machinability, helping you achieve cleaner surfaces with each pass.

This tool also offers the flexibility of various corner radii, enabling precise, tailored milling for complex mold features. The long shank provides the reach and stability needed for deep groove machining, while the 4-flute configuration delivers steady, reliable cutting in demanding materials.

• Variable Index Geometry: Optimizes edge distribution to reduce cutting forces and promote efficient chip evacuation for smoother cuts and better surface finish.
• Long Shank for Deep Grooves: Provides extended reach and stability ideal for deep cavity milling and intricate grooves.
• 4-Flute Design with Corner Radius R0.2: Delivers stable, precise cutting with a defined corner radius for accurate mold and die features.

With carbide construction and the optimized geometry, this end mill supports efficient workflows in mold and die projects, delivering consistent results, easier setup, and improved feature accuracy across parts. The combination of variable index, long reach, and corner-radius options helps you tackle deep cavities and tight tolerances with confidence, boosting productivity and overall part quality.
