Widin Carbide Corner Radius End Mill is a precision cutting tool designed for CNC operators and machinists working with hard-to-cut materials. With a 4 mm diameter, 16 mm cutting length and a 0.3 mm corner radius, this 2‑flute stub end mill delivers reliable performance on high-hardness workpieces.

• Material: Solid carbide construction for superior hardness and wear resistance, extending tool life in tough materials.
• Diameter: 4 mm cutting diameter for precise pockets, slots, and profiles.
• Cutting Length: 16 mm effective cutting length (stub) for controlled depth of cut and rigidity.
• Corner Radius: 0.3 mm radius to produce clean internal corners and reduce stress concentration.
• Flute Configuration: 2-flute design that facilitates efficient chip evacuation and smooth finishes on challenging workpieces.
• Design Focus: Optimized for high-hardness workpieces, delivering consistent performance in hardened steels and similar alloys.

This end mill supports accurate feature creation with clean corners, minimal burr formation, and stable tool life. The combination of a short, rigid stub length and a simple two-flute geometry helps reduce deflection, making it well-suited for precision die/mold features, pockets, and slots in demanding materials. Use this tool to achieve repeatable tolerances and reliable results across multiple passes in high-hardness applications.
