Widin Carbide Rib Processing End Mill - 2 Flute Ball Nose (ESRB712004025) - 0.4mm x2.5mm (4mm Shank Dia)

The WidIn Carbide Rib Processing End Mill, model WB712P (ESRB712004025), is a precision cutting tool built for rib geometry and narrow features. With a cutting diameter of 0.4 mm, a 2.5 mm flute length, and a 4 mm shank, it delivers tight, repeatable radii and smooth surfaces on challenging rib profiles.

Made from high-quality carbide for exceptional durability and wear resistance, this tool maintains sharpness through long runs and across materials such as aluminum and steel. The two-flute, ball-nose design provides accurate curved surfaces and reliable finish, while the sharp cutting edges and optimized flute geometry support steady chip evacuation and reduced clogging.

• Ball Nose geometry for smooth curved contours: Creates accurate radii on narrow ribs and curved surfaces, delivering a superior surface finish and precise dimensional control.
• 2-flute design with optimized chip evacuation: Sharp edges and flute geometry promote clean cuts, reduced chatter, and efficient removal of chips for steady machining and less downtime.
• Compact, rigid small-diameter tool: 0.4 mm cutting diameter with a 4 mm shank and 2.5 mm flute length provide stability and precision in tight rib features, minimizing deflection and improving repeatability.

Designed for engineers, machinists, and workshop operators, this end mill helps you achieve consistent rib profiles with minimal finishing work. Expect longer tool life, fewer tool changes, and reliable performance across common materials, empowering faster setups, smoother runs, and higher-quality results in every job.
