Widin Carbide Corner Radius End Mill - 4 Flute - 3mm x R0.3

Widin's Carbide Corner Radius End Mill is a precision cutting tool for machinists who regularly tackle hard materials and tight-radius features. This 3 mm diameter, 0.3 mm corner radius, 4-flute end mill delivers clean corners and efficient material removal in demanding applications.

• Diameter & Corner Radius: 3 mm diameter with a 0.3 mm corner radius for precise corners and smooth finishes.
• Flute Count: 4 flutes provide a balanced cutting load and efficient chip evacuation.
• Material: Carbide construction delivers exceptional hardness resistance and long tool life.
• Helix Angle: 45° helix enables high-speed cutting and stable feed rates for demanding passes.
• Cutting Edge Design: Optimized geometry reduces load on hard workpieces and minimizes deflection.
• Applications: Ideal for milling hardened materials, intricate pockets, and precise corner radii.
• Machinability & Reliability: Consistent performance across multiple passes with reduced downtime.

With this end mill, you gain reliable, repeatable results when milling hardened steels and other high-hardness alloys. The 45° helix promotes smooth entry and exit, improving surface finish and reducing heat buildup. The 3 mm diameter paired with a 0.3 mm corner radius enables tight, accurate radii without sacrificing material removal speed, making it well-suited for detailed enclosures, fillets, and pocket edges. Built for demanding machining environments, it integrates well with rigid setups and robust CNC machines, helping shops boost productivity and extend tool life.
