Widin Carbide Radius End Mill - 4 Flute 45° Helix - 4mm x 0.3mm (4mm Shank)

The Widin Carbide Radius End Mill is a versatile cutting tool designed for contouring, profiling, and slotting across a wide range of materials. With a 4-flute configuration, a 45° helix, and a precise 0.3 mm radius at the nose, it delivers clean, dimensionally accurate cuts and smooth finishes in a variety of machining tasks. The 4 mm shank provides robust rigidity for demanding operations and broad compatibility with standard tool holders.

Built from carbide for outstanding hardness, wear resistance, and long tool life, this end mill stands up to tough jobs in production and hobbyist setups alike. The radius nose supports gentle, precise transitions on curved paths, while the 45° helix promotes stable engagement with the workpiece and efficient chip evacuation to reduce heat and improve surface quality.

• 0.3 mm radius nose: Enables smooth contouring and precise profiling for complex shapes, reducing the need for extra finishing passes and delivering better edge quality.
• 4-flute carbide design: Combines durability with efficient chip evacuation, helping maintain a cooler cut and extending tool life in challenging materials.
• 45° helix for stability: Enhances cutting stability and minimizes tool deflection, supporting consistent finishes and reliable performance in demanding applications.

Whether you're shaping internal pockets, outlining intricate profiles, or slotting tight channels, this end mill delivers dependable, repeatable results. The carbide construction, together with the radius nose and optimized helix, helps you reduce downtime, improve surface quality, and achieve better throughput in everyday machining tasks.
