Widin's Carbide Corner Radius End Mill is a precision cutting tool designed for engineers and machinists tackling intricate milling tasks in hard materials. Built with ultra-fine grain carbide, it delivers durable performance and consistent results in demanding CNC applications.

• Tip diameter: 0.4 mm
• Flutes: 2 flutes for efficient material removal
• Helix angle: 30° for effective chip evacuation and smooth cutting
• Corner radius: R0.05 for gentle edge relief and reduced wear on workpieces
• Center cutting: Yes, enabling plunging and contouring in a single tool
• Neck design: Long-neck with back-draft geometry to enhance reach and minimize vibration
• Material: Ultra-fine grain carbide delivers high rigidity and wear resistance
• Hard-material capability: Suitable for machining high-hardened materials up to HRc70
• Rake-angle adaptability: Neck length can be effectively adjusted based on rake angle for versatile operations

This end mill is engineered to deliver precise, repeatable cuts in challenging applications, from micro-milling and engraving to pocketing and finishing on hard steels. The combination of a tight corner radius, robust carbide, and a long-neck back-draft design reduces chatter and tool deflection, helping you achieve clean edges, tight tolerances, and longer tool life across deep grooves, angled surfaces, and complex geometries. Whether you’re refining small features or machining through hardened workpieces, this end mill provides dependable performance and flexible operation.
