Widin Carbide Corner Radius End Mill - 2 Flute Long Neck Back Draft Type - 1mm x4mm x R0.2

The Widin Carbide Corner Radius End Mill is a precision 2‑flute carbide cutting tool designed for micro‑machining and deep pocket work in hard materials. Its long neck and back‑draft geometry deliver stable, accurate cuts and smooth edges on challenging surfaces.

• Material: Ultra‑fine grain carbide for exceptional strength, wear resistance, and long tool life.
• Flutes: 2 flutes provide efficient chip evacuation and a clean, precise finish.
• Helix angle: 30° for smooth cutting, reduced vibration, and effective debris removal.
• Center cutting: Yes, enabling plunging and versatile contour milling.
• Corner radius: R0.2 radius creates smooth edges and lowers wear on both tool and workpiece.
• Design features: Long neck and back‑draft type enhance stability, reduce chatter, and improve performance on deep grooves and sloped surfaces.
• Hardness capability: Suitable for machining high‑hardness materials up to HRc70, expanding its application range.

This end mill is ideal for precision components, hard‑metal work, and applications where edge quality, dimensional accuracy, and tool stability are critical. The combination of a tiny cutting diameter, corner radius, and a long neck makes it well suited for deep cavities, intricate profiles, and contouring tasks, while maintaining reliable performance across demanding materials. For best results, match speeds and feeds to the material and use appropriate cooling to sustain sharpness and finish.
