Widin Carbide Rib Processing End Mill - 2 Flute Ball Nose (ESRB71201204) - 1.2mm x4mm (4mm Shank Dia)

The Widin Carbide Rib Processing End Mill - 2 Flute Ball Nose is a precision cutting tool designed specifically for rib processing and delicate contour work. Built for engineers, machinists, and hobbyists who demand consistent, high-quality profiles on narrow ribs, it delivers clean, repeatable results with each pass.

With a cutting diameter of 1.2 mm and a 4 mm shank, the WB712P combines a carbide body with a ball nose to handle curved surfaces and intricate features. The two-flute design, along with optimized flute geometry, promotes efficient cutting and reliable chip evacuation across aluminium, steel, and other materials.

• Ball Nose geometry for precise curves: The rounded tip maintains smooth transitions on curved rib profiles, enabling accurate contours and excellent surface finish with fewer finishing passes.
• Durable carbide construction for extended tool life: Carbide tooling offers superior wear resistance for repeated use across aluminium, steel, and other materials, reducing tool changes and downtime.
• Two-flute design with optimized chip evacuation: Two cutting edges and refined flute geometry ensure efficient chip removal, minimizing clogging and keeping feeds consistent for reliable, repeatable cuts.

This end mill helps you streamline workflows by delivering consistent rib contours, reducing the number of passes, and improving first-pass finish. The compact 1.2 mm cutting diameter is ideal for tight rib features, while the 4 mm shank fits common tool holders, making it a versatile choice for both CNC milling and manual setups. With its carbide construction and precision geometry, you get dependable performance across materials like aluminium and steel, enabling you to produce accurate parts, reduce waste, and shorten production cycles.
