The Widin Carbide Corner Radius End Mill is a precision cutting tool built for machinists who work with hard-to-machine materials. With a 4 mm diameter, 25 mm overall length, and a 0.5 mm corner radius, this 4‑flute stub end mill delivers reliable corners and clean finishes in a compact, rigid package.

• Diameter: 4 mm
• Cutting length: Stub length for increased rigidity and controlled engagement
• Overall length: 25 mm
• Flutes: 4-flute design for efficient chip evacuation and smooth cutting
• Corner radius: 0.5 mm for durable, consistent fillets and finished corners
• Material: Carbide, offering high hardness resistance and wear life

The combination of a stub-cut length, four flutes, and a carbide composition makes this end mill well-suited for precise milling of hard materials, including hardened steels and alloys. The 0.5 mm corner radius enables clean, reliable fillets without sacrificing rigidity, while the compact geometry minimizes tool deflection and vibration during high-precision passes. Whether you’re deburring sharp edges or defining smooth radii in tight pockets, this end mill provides predictable performance, consistent finishes, and longer tool life in demanding machining scenarios.
