Widin Carbide End Mill - 2 Flute Long Neck- Ball Nose - 0.4mm x 3.5mm

Widin Carbide End Mill – 2 Flute Long Neck Ball Nose is a precision cutting tool designed for intricate contouring, pockets, and profiling across a range of materials. With a 0.4 mm diameter and a long neck geometry, it reaches tight spaces while delivering accurate, repeatable features. The tight tolerance of +0/-0.005 mm ensures precise dimensions across passes, helping you minimize rework. Its center-cutting ball nose enables reliable plunging and smooth 3D contours, while the 30° helix supports efficient cutting and clean finish. The tapered neck reduces vibration and chatter, improving surface quality and dimensional stability, and the effective neck length can be adjusted to match different rake angles. Engineered with advanced raw materials and coating, it enables dry cutting and high-speed machining, boosting productivity and tool life.

• Center-cutting ball nose geometry: Enables accurate plunging and smooth, continuous 3D contours in a single pass, reducing secondary operations and improving part accuracy.
• Long neck with tapered design: Provides extended reach for deep pockets and sloped surfaces while suppressing vibration and chatter for better surface finish and dimensional control.
• High-hardness capability with dry-cut coating: Machined hardened materials up to HRc70 and support for dry cutting and high-speed machining, increasing process efficiency and tool life.

This end mill helps you streamline production, deliver precise features, and finish parts faster. The combination of tight dimensional control, deep-reach capability, and durable carbide with a forward-looking coating means fewer tool changes, less downtime, and consistently high-quality results across demanding applications.
