Widin Carbide Rib Processing End Mill - 2 Flute Ball Nose (ESRB71203516) - 3.5mm x16mm (4mm Shank Dia)

The Widin Carbide Rib Processing End Mill — 2 Flute Ball Nose (WB712P) is a precision cutting tool designed for rib profiling and narrow-contour work. With a 3.5 mm cutting diameter and 16 mm flute length on a 4 mm shank, it delivers controlled material removal and a smooth surface on complex rib geometries. Built for versatility, it handles aluminum, steel, and other common materials with reliable performance.

Engineers, machinists, hobbyists, and fabricators will appreciate its balance of control and durability. The carbide construction delivers exceptional wear resistance for long tool life, while the ball nose geometry enables smooth transitions on curved surfaces and tight radii, helping you achieve precise results with fewer finishing steps. The 4 mm shank supports standard collets and holders, making integration into existing CNC setups straightforward.

• Ball nose geometry for smooth curved surfaces: The rounded tip creates gentle transitions on ribs and intricate details, delivering consistent surface finish and precise radii on every pass.
• Two-flute design with optimized flute geometry: Efficient chip evacuation and stable cutting reduce chatter, enabling faster feeds and reliable performance on challenging materials.
• Carbide construction for durability: High wear resistance extends tool life, minimizes replacements, and maintains dimensional accuracy across aluminum, steel, and other common workpieces.

With these features, the tool helps you achieve precise rib profiles in fewer passes, reduces downtime due to tool changes, and delivers consistent finishes that require less post-processing. Its robust carbide composition and optimized geometry support reliable results across materials, making it a trusted choice for both production and prototyping environments.
