Widin Carbide End Mill - 2 Flute Long Neck- Ball Nose - 0.4mm x 2.5mm

The Widin Carbide End Mill is a 2-flute ball-nose micro end mill designed for precision contouring in hard metals and plastics. Its long-neck geometry lets you reach deep into grooves and along sloped surfaces, while the center-cutting design enables clean plunging and starting cuts with confidence.

With a tight tolerance of +0/-0.005 mm and a 30° helix for efficient chip evacuation, this tool maintains accuracy through demanding passes. The taper neck reduces vibration and chatter for a smoother surface finish, and the neck length can be adjusted to suit different rake angles across workpieces. Engineered to machine high-hardened materials up to HRc70, it combines a premium raw material with an advanced coating to enable dry cutting and high-speed machining, boosting productivity and tool life.

• Center-cutting ball-nose geometry: Enables plunge milling and precise 3D contouring with smooth finishes on complex profiles.
• Taper neck design to reduce vibration: Minimizes chatter and improves surface finish and dimensional accuracy on difficult features.
• Adjustable neck length for versatile rake angles: Lets you tailor reach and cutting conditions to your workpiece, enhancing stability and consistency.

This end mill is built for reliability in tough environments, delivering consistent performance across shifts and materials. The combination of ball-nose geometry, long-neck reach, and robust coating supports clean finishes, tight tolerances, and longer tool life, helping you complete intricate parts with fewer passes and less rework. Whether you’re machining high-hardness steels, hardened alloys, or precision plastics, this tool offers dependable results and confident, repeatable performance.
