Description
Widin Carbide Corner Radius End Mill for Stainless & Exotics is a precision carbide cutting tool designed to tackle tough materials. This 4-flute end mill features a 4 mm cutting diameter and a 0.5 mm corner radius, delivering accurate radii on challenging parts with dependable performance. The 4-flute, variable geometry profile is built to handle demanding milling tasks in stainless steels and exotic alloys.
- Unequal-Index 4-Flute Design: Improves chip emission and delivers a smooth workpiece surface finish, reducing heat buildup and promoting cleaner cuts on hard-to-machine materials.
- High-Hardness Carbide Cutting Edge: Provides excellent wear resistance for longer tool life and reliable performance under demanding milling conditions.
- Corner Radius Versatility (R0.5): Supports precise radii with options for various corner sizes, enabling flexibility for different projects and tight tolerances.
This end mill helps you achieve precise corners and smooth surface finishes in stainless and exotic materials, boosting workflow efficiency and part quality. Its wear-resistant carbide edge minimizes downtime from tool wear, while the unequal-flute geometry ensures consistent cutting performance. With adaptable corner radii, you can tackle a broader range of applications with confidence and repeatable results.
