Widin Carbide Rib Processing End Mill - 2 Flute Ball Nose (ESRB71201220) - 1.2mm x20mm (4mm Shank Dia)

The Widin Carbide Rib Processing End Mills — 2 Flute Ball Nose (WB712P, ESRB71201220) are compact, high-performance tools designed specifically for rib detailing. With a 1.2 mm cutting diameter, 20 mm flute length, and a 4 mm shank, they excel at creating precise, smooth contours in narrow ribs. Whether you’re prototyping or finishing production parts, these end mills help you achieve clean, accurate profiles in a single pass.

Crafted from carbide for outstanding wear resistance, they stay sharp longer and resist wear across a range of materials, reducing tool changes and downtime. The ball nose geometry smoothly handles curved surfaces and intricate details, delivering superior surface finish and tight dimensional accuracy on aluminum, steel, and other common workpieces.

• Ball Nose for Smooth Curves: The ball nose profile creates gentle radii and seamless transitions on narrow ribs, improving contour quality and reducing the need for additional finishing passes.
• Durable Carbide Construction: Carbide’s hardness provides long tool life and reliable performance in diverse materials, cutting costs on replacements and downtime.
• Efficient Chip Evacuation: Optimized flute geometry and sharp cutting edges promote fast chip clearance, minimize clogging, and support consistent finishes on curved surfaces.

This end mill enables faster, more predictable rib machining with repeatable results, helping you improve workflow efficiency, shorten setup times, and achieve high-precision finishes across aluminum, steel, and other common materials.
