Description
The Widin XCR504 Carbide Corner Radius End Mill is engineered to tackle stainless steel and exotic materials with precision and reliability. With a 20 mm diameter and a 1.0 mm corner radius, this tool delivers consistent, predictable results for engineers, machinists, and hobbyists working on demanding parts. Its 4-flute double-core design provides standout stability, while the variable helix geometry reduces vibration for smoother cuts and improved productivity.
- Corner Radius for Durability: The precise 1.0 mm corner radius minimizes chipping and edge breakouts, extending tool life and preserving part dimensions even in tough aerospace alloys and exotics.
- 4-Flute Double-Core Stability: Built for rigidity, this design delivers reliable chip control and consistent tool paths, helping you achieve accurate finishes and extended tool life in hard materials.
- Variable Helix for Smooth Cutting: The staggered helix reduces vibration and chatter, delivering smoother surfaces, cleaner edges, and lower stress on the tool during aggressive cutting.
Designed for versatility and dependable performance, the Widin XCR504 helps you meet tight tolerances and finish requirements across stainless steels, titanium, Inconel, and other exotic alloys. It improves workflow by delivering stable cutting, predictable results, and longer tool life, so you can complete projects with confidence and fewer tool changes.
