Widin Carbide Rib Processing End Mill - 2 Flute Ball Nose (ESRB71201540) - 1.5mm x40mm (4mm Shank Dia)

The Widin Carbide Rib Processing End Mills - 2 Flute Ball Nose (WB712P) are precision carbide cutting tools designed for rib profiling tasks. With a cutting diameter of 1.5 mm, an overall length of 40 mm, and a 4 mm shank, these end mills are built to fit standard collet systems while delivering accurate, repeatable results on narrow ribs. Their compact size makes them ideal for precision work in constrained cavities and thin-walled components.

Designed for engineers, fabricators, and hobbyists alike, the ball nose geometry enables smooth curves and intricate details, delivering excellent surface finish and tight dimensional control on a range of materials, including aluminium and steel. The WB712P’s robust carbide construction provides exceptional wear resistance, helping you push longer tool life and consistent performance from job to job.

• Ball Nose geometry for smooth, curved surfaces: Reproduces gentle radii and fine details with a superior surface finish, helping you achieve precise rib contours and consistent fillets.
• Durable carbide with long tool life: Hardened carbide resists wear and maintains sharp cutting edges, reducing replacement frequency and downtime across aluminum, steel, and mixed-material parts.
• Optimized 2-flute design for efficient cutting: Two flutes provide stable cutting and effective chip evacuation, lowering the risk of clogging and enabling steadier finishes on narrow rib profiles.

This end mill is built to support reliable, repeatable results across a variety of rib-work applications—from small batch prototypes to production runs. The WB712P helps you maintain precise dimensions, achieve smooth surface finishes, and keep your workflow moving with dependable performance from setup to part completion.
