Description
The Widin XCR504 Carbide Corner Radius End Mill is a high‑performance cutting tool designed for stainless steel and exotic alloys. With an 8 mm diameter and a 0.5 mm corner radius, it delivers precise, clean profiles while resisting chipping under demanding conditions. The 4‑flute, double‑core design provides exceptional rigidity, helping you maintain accurate tool paths and stable cutting in tough materials.
The variable‑helix geometry reduces vibration for smoother cuts, improved surface finishes, and longer tool life. This makes the XCR504 particularly effective on aerospace alloys, titanium, Inconel, and other exotics, where consistent results and reliable performance are essential.
- 4‑Flute Double‑Core Construction: Delivers superior rigidity and stability during heavy milling, minimizing deflection and producing consistent, high‑quality finishes on stainless and exotic alloys.
- Variable Helix Geometry: Reduces vibration and chatter for smoother cuts, higher feed rates, and more predictable results in challenging materials.
- Corner Radius for Durability: The 0.5 mm corner radius helps prevent chipping at the tool edge, extending tool life and preserving accurate radii on curved profiles.
This end mill combines robust construction with smart geometry to enhance reliability, reduce downtime, and improve finishing quality across demanding applications. Whether you’re producing aerospace components, turbine parts, or precision stainless work, the Widin XCR504 delivers consistent performance you can trust.
