Widin Carbide Corner Radius End Mill - 2 Flute Long Neck Back Draft Type - 2mm x20mm x R0.3

Introducing the Widin Carbide Corner Radius End Mill — a precision cutting tool built for machinists tackling hard materials and intricate geometries. With a compact 2 mm diameter, 20 mm cutting length, and a corner radius of 0.3 mm, this 2-flute end mill delivers clean edges, repeatable accuracy, and dependable performance in demanding applications.

• Diameter / Cutting Length: 2 mm diameter with 20 mm length of cut and a precise corner radius of R0.3 mm for controlled finishes in tight pockets and narrow slots.
• Flute Count & Helix: 2-flute design with a 30° helix for efficient chip evacuation and smoother cutting across hard and soft materials alike.
• Center Cutting: Center-cutting capability enables plunging and profile milling, expanding its versatility for complex contours.
• Corner Radius: Corner radius of R0.3 mm softens edges, reduces edge wear, and minimizes burr formation on finished parts.
• Geometry: Long Neck & Back Draft: Long neck plus back draft geometry provide enhanced reach, improved stability, and reduced vibration when cutting deep grooves or angled surfaces.
• Material & Coating: Ultra-fine grain carbide substrate designed for high rigidity and wear resistance (uncoated for dependable performance in precision work).
• Hardness Capability: Specifically engineered to machine high-hardened materials up to HRc70, making it suitable for tool steels, hardened alloys, and difficult-to-machine components.
• Adjustable Neck Length: Flexible neck-length behavior tied to rake angle allows optimization across a range of milling operations and feature geometries.

This end mill is ideal for engineers and machinists who need reliable edges in deep grooves, complex contours, and surfaces with slopes. Use cases include mold making, aerospace components, automotive parts, and precision dies where maintaining tight tolerances and clean finishes matters most. The combination of a small diameter, strong carbide core, and thoughtful geometry helps you achieve accurate cuts, longer tool life, and consistent results even in challenging materials.
