Widin Carbide Rib Processing End Mill - 2 Flute Ball Nose (ESRB71202040) - 2mm x 40mm(4mm Shank Dia)

The Widin Carbide Rib Processing End Mill – 2 Flute Ball Nose (WB712P) is a precision cutting tool designed specifically for rib processing and narrow rib contours. With a 2 mm cutting diameter, 40 mm flute length, and a 4 mm shank, this carbide end mill delivers accurate radii and smooth finishes on curved rib profiles. Built for durability, it’s ideal for engineers, machinists, and hobbyists who need reliable, repeatable results in demanding rib-machining tasks.

The ball nose geometry lets you machine curved surfaces and intricate details with exceptional surface quality and dimensional accuracy. Compatible with aluminum, steel, and other common materials, the WB712P maintains consistent performance across a range of applications. Sharp cutting edges and optimized flute geometry promote efficient chip evacuation, reducing clogging and keeping your workflow moving smoothly.

• Ball Nose Geometry for Smooth Contours: Creates flawless radii on curved rib profiles and delivers high-quality surface finishes with minimal secondary finishing.
• Durable Carbide for Extended Tool Life: Hard carbide resist wear for longer tool life and fewer tool changes in repetitive rib-cutting work.
• Compact 2 mm Diameter with Stable 4 mm Shank: Access tight rib features while maintaining rigidity and precise tolerances, thanks to a stable shank that minimizes deflection during cutting.

Designed to streamline rib-work, the WB712P helps you reduce setup time, lowers the risk of rework, and consistently achieve accurate radii and smooth surfaces. Its small diameter enables access to tight rib geometries, while the carbide construction and efficient chip evacuation support faster cycles and fewer interruptions—so you can complete projects with confidence and repeatable results.
