The Widin Carbide Corner Radius End Mill is a high-precision cutting tool designed for micro-machining tasks on hard materials. With a 1.5 mm cutting diameter, a 4 mm shank, and a precise R0.2 corner radius, it's ideal for engineers and machinists who need exact edges and reliable performance in tight pockets.
- Diameter: 1.5 mm cutting diameter for precise, small-feature milling
- Flute Count: 4-flute design to balance aggressive material removal with a smooth finish
- Cutting Length: 4 mm stub-cut length for rigidity and reduced deflection during shallow passes
- Shank Diameter: 4 mm shank compatible with standard collets and holders
- Corner Radius: R0.2 mm for controlled edge radii and sharp, repeatable corners
- Material: Solid carbide for exceptional hardness, wear resistance, and long tool life
- Series: Part of the ZR704 family, offering versatile corner radii and effective lengths to suit specific machining needs
Designed to tackle high-hardness workpieces with confidence, this end mill delivers reliable performance across a range of small-feature machining tasks. The 4-flute configuration promotes steady chip evacuation and clean finishes, while the stub-cut length minimizes chatter and deflection in precision operations. Use it to create precise corners, consistent radii, or tight fillets in hardened steels, alloys, and demanding materials where exact geometry matters. The tool’s carbide composition ensures longevity and consistent performance even under frequent finishing passes, making it a practical choice for micro-milling, mold work, and intricate component fabrication.
