Widin Carbide Corner Radius End Mill For Mold & Die - Variable Index 4 Flute - 5mmx 15mm X R0.3

Widin Carbide Corner Radius End Mill for Mold & Die is a high-performance cutting tool designed for mold and die machining. Its variable-index geometry improves machinability and enables efficient chip evacuation, reducing cutting forces and delivering a smoother surface finish.

With a 5 mm diameter, 15 mm length of cut, a 0.3 mm corner radius (R0.3), and a long shank, this four-flute end mill delivers the reach and stability needed for deep grooves and tight features found in mold and die work.

• Variable index geometry for reduced cutting forces: Distributes the cutting load across flutes for smoother cuts, less tool wear, and consistent performance in tough materials.
• Efficient chip evacuation and superior surface finish: Optimized flute arrangement helps chips exit fast, minimizing built-up edge and delivering cleaner, more accurate surfaces.
• Long shank for deep grooves and precise corners: Extended reach and rigidity enable reliable cutting in deep pockets and narrow slots while maintaining the 0.3 mm corner radius.

This end mill supports faster, more predictable mold and die production by combining aggressive material removal with controlled cutting dynamics. The reliable corner radius, sturdy long shank, and chip-evacuation efficiency translate to fewer stops, less rework, and better surface quality across a range of carbide materials and tough alloys. Whether you’re refining a part as an engineer, preparing components in a shop, or tackling precise, intricate molds, this tool helps you achieve consistent results with confidence.
