Description
The Widin XCR504 Carbide Corner Radius End Mill is engineered for precision milling in stainless steel and exotic materials. With a 20 mm diameter and a 0.5 mm corner radius, this 4‑flute tool delivers stable, accurate cuts even in challenging alloys.
Its 4‑flute double‑core design enhances rigidity and chip evacuation for consistent performance, while the variable helix reduces vibration for smoother cutting and better surface finishes. Ideal for aerospace alloys, titanium, Inconel, and other exotics, the XCR504 helps you achieve reliable results and longer tool life in demanding applications.
- 4‑Flute Double‑Core Construction: Increases rigidity and reduces chatter for repeatable, precise milling in stainless and exotic materials.
- Variable Helix Geometry: Minimizes vibration and heat buildup for smoother cuts, leading to improved surface finish and longer tool life.
- Corner Radius R0.5 Profile: Shields cutting corners from chipping, extending tool life and preserving edge quality in tough pockets.
With the Widin XCR504, you get a reliable, high‑performance end mill that supports faster setups, cleaner surfaces, and consistent results across demanding jobs. Its combination of rigidity, vibration control, and corner‑edge protection reduces downtime and rework, helping you finish parts to specification with confidence.
