Description
The Widin XCR504 Carbide Corner Radius End Mill is designed for precision machining of stainless steel and exotic alloys. With an 8 mm cutting diameter and a 1.0 mm corner radius, this end mill combines a 4-flute double-core design for superior stability with a variable helix to minimize vibration and deliver smoother cuts.
Its corner radius profile minimizes chipping and extends tool life even in the most demanding applications. Suited for aerospace alloys, titanium, Inconel, and other exotics, the XCR504 helps you achieve excellent surface finishes and reliable performance under tough conditions. Experience versatile, productive performance with this premium Widin end mill.
- Corner Radius for Reduced Chipping: The 1.0 mm corner radius preserves edge integrity and minimizes chipping during heavy cuts, helping extend tool life and maintain accurate radii on challenging materials.
- 4-Flute Double-Core Stability: A rigid, two-core design reduces deflection and vibration, delivering more consistent chip loads and smoother finishes across stainless and exotic alloys.
- Variable Helix for Smoother Cutting: The staggered helix geometry lowers vibration and chatter, enabling cleaner surfaces and higher productivity on hard-to-machine materials like Inconel and titanium.
By combining stability, vibration control, and durable edge geometry, the Widin XCR504 delivers repeatable toolpaths, superior surface quality, and longer tool life. This translates to faster cycles, fewer tool changes, and reliable performance in demanding applications across aerospace, automotive, and high-performance manufacturing environments.
