Widin Carbide Radius End Mill - 4 Flute Long Shank - 3mm x 0.5mm (4mm SHANK)

Widin Carbide Radius End Mill is a precision cutting tool designed for a wide range of machining tasks. With a 3 mm cutting diameter and a 0.5 mm radius, it excels at smooth contouring, filleting, and slotting in both ferrous and non-ferrous alloys. The long shank design, featuring a 4 mm diameter, provides extended reach for deep cavities while preserving rigidity for accurate cuts.

• Radius end geometry for smooth contours: The built‑in 0.5 mm radius creates precise fillets and gentle transitions, enabling accurate profiling and clean slotting with fewer passes and a superior surface finish on complex edges.
• Long shank with 4 mm diameter for reach and rigidity: The extended length and sturdy shank reduce deflection when machining deep pockets, delivering stable engagement and consistent depths in challenging workpieces.
• Four-flute carbide for efficient cutting and durability: Four flutes balance effective chip evacuation with strong cutting forces, supporting higher feed rates while resisting wear for longer tool life across a range of alloys.

This end mill helps you finish parts faster with repeatable results, delivering reliable contouring, profiling, and slotting across ferrous and non-ferrous materials. The combination of carbide durability, precise radius geometry, and a rigid long shank supports efficient workflows, minimizes downtime, and enhances overall machining performance.
