The Widin Carbide Corner Radius End Mill is a precision micro-cutting tool designed for engineers and machinists who demand clean corners and reliable performance in tight tolerances. Built from ultra-fine grain carbide, it delivers durability and consistent cuts in demanding materials.
- Diameter: 0.4 mm
- Cutting Length: 4 mm
- Corner Radius: R0.05 mm
- Flutes: 2-flute design for efficient chip evacuation and a smooth surface finish
- Helix Angle: 30° for effective chip flow and stable cutting
- Center Cutting: Yes, enabling plunging, pocketing, and contouring
- Neck & Back Draft: Long neck with back-draft geometry to minimize vibration and improve stability
- Material & Hardness: Ultra-fine grain carbide suitable for high-hardened materials up to HRc70
This end mill is designed to reduce chatter, deliver precise corner radii, and extend tool life in challenging workpieces. The long neck supports deep slots and angled surfaces, while the back-draft geometry stabilizes cutting forces for consistent finishes. With center-cut capability and a 30° helix, it handles ramping, plunging, and slotting tasks efficiently, making it a reliable choice for micro-machining, deburring, and edge finishing on hard materials.
