Widin Carbide Corner Radius End Mill is a precision cutting tool designed for hard-to-machine materials and tight radii. Ideal for toolmakers and CNC operators, it delivers clean corners and consistent finishes with a 1 mm cutting diameter, 4 flutes, and a stub-cut length for rigidity in micro-milling tasks.
- Diameter: 1 mm cutting diameter for precise detail in small features
- Corner Radius: R0.3 mm corner radius (R0.3) for sharp internal/external corners and smooth radii
- Flute Count: 4-flute design for efficient chip evacuation and smoother finishes
- Shank Diameter: 4 mm shank for robust rigidity in small-diameter milling
- Cutting Length: Stub-cut length to minimize tool deflection and maintain accuracy
- Material: Carbide construction for stability on high-hardness workpieces
- ZR704 Geometry: Part of the ZR704 family, offering optimized corner radii and effective lengths for flexible, precise machining
With this end mill, you can tackle challenging corners and tight radii in hardened materials, achieving accurate 0.3 mm radii and crisp edges without sacrificing speed. The 4-flute configuration manages chip load efficiently, leading to improved surface finish and extended tool life. The stub-cut geometry provides rigidity, minimizing deflection on small-diameter cuts, which translates to higher part quality and less rework. Its 1 mm diameter makes it ideal for micro-milling tasks, precision housings, and small fixtures where space is tight. The carbide construction withstands wear in demanding materials, delivering consistent performance across long runs.
