Widin's Carbide Corner Radius End Mill is a precision cutting tool crafted for micro-machining and high-hardness materials. Ideal for engineers, machinists, and mold makers, it delivers reliable, high-accuracy cuts in tight pockets and complex profiles.

• Tip diameter: 0.2 mm for exceptional detail and fine-feature engraving in hard materials.
• Cutting length: 0.5 mm (length of cut) to enable precise shallow passes and controlled material removal.
• Corner radius: R0.05 for smoother edges, reduced burrs, and improved part longevity.
• Flutes: 2-flute design that optimizes chip evacuation and maintains rigidity at small diameters.
• Helix angle: 30° to promote efficient chip control and a clean surface finish.
• Center cutting: Yes, enabling plunging cuts for pocketing, slotting, and profile milling.
• Back draft / Long neck: Long neck and back-draft geometry boost stability, lowering vibration and chatter in deep grooves and sloped surfaces.
• Material compatibility: Ultra-fine grain carbide built to machine high-hardened materials up to HRc70, expanding capability into hardened steels and difficult alloys.
• Neck length adjustability: Flexible neck length behavior aligned with rake angle, supporting varied machining operations with minimal setup changes.

This end mill translates its advanced geometry and robust carbide construction into practical benefits: tighter tolerances, smoother edges, and repeatable finishes even when machining challenging materials. The combination of a small tip with a controlled corner radius reduces corner wear, while the long neck unlocks depths that would challenge shorter tools. Whether you’re creating precision dies, molds, or aerospace-grade components, this tool is designed to deliver dependable performance across demanding applications.
