Description
The Widin Carbide Corner Radius End Mill is a high-performance cutting tool designed for machinists who tackle hard materials and tight corners. With a 3 mm cutting diameter and an R0.5 corner radius, this 4-flute end mill delivers precise, controlled material removal and reliable performance in demanding applications.
- Diameter: 3 mm
- Corner Radius: R0.5
- Flutes: 4-flute configuration for efficient material removal
- Shank: Long shank design for extended reach into deep grooves
- Material: Carbide for hardness resistance and durability
- Cutting Edge Design: High-strength, radius-enhanced edge for stable cutting in tough materials
- Applications: Ideal for high-hardness workpieces and deep groove machining
Designed for stability and longevity, the ZR734 variant (as part of the Widin line) combines a robust cutting edge with extended reach. The long shank enables access to deep pockets and channels, while the 4-flute geometry helps manage chip evacuation and maintain rigidity during heavy cuts. This makes it well-suited for precision milling in hardened steels and complex molds where clean corners and consistent finishes matter.
