Widin Carbide End Mill - 2 Flute Long Neck- Ball Nose - 0.3mm x 3mm

The Widin Carbide End Mill is a precision 2-flute, long-neck ball-nose cutter designed for detailed micro-machining. With a center-cutting geometry and a 30° helix, it handles plunging and complex contouring with steady, accurate cuts. The 0.3 mm diameter and extended reach make it ideal for deep grooves, tight radii, and sloped surfaces across hard materials.

Built for reliability and long-term performance, this end mill delivers tight dimensional control and durable cutting capability. It offers a tolerance of +0/-0.005 mm and is engineered to machine high-hardened materials up to HRc70. The tapered neck reduces vibration and chatter, while the effective neck length can be adjusted to suit different rake angles. A newly developed raw material and advanced coating enable dry cutting and high-speed machining, boosting productivity and tool life.

• Ball Nose with Center-Cutting Geometry and 30° Helix: Ball-nose tip delivers smooth radii on complex contours, center-cutting enables plunging, and the 30° helix improves chip evacuation for cleaner finishes.
• Long-Neck, Vibration-Reducing Design: Tapered neck minimizes tool chatter and vibration; adjustable neck length allows you to tailor rake angles for stable cuts in deep pockets and steep walls.
• Ultra-Tight Tolerance with Hard-Material Capability: +0/-0.005 mm accuracy ensures repeatable results, while carbide construction and coating support dry cutting and high-speed milling of hard materials up to HRc70.

By combining precise geometry, vibration control, and rugged hardness capability, this end mill helps you achieve accurate profiles, deep grooves, and smooth surface finishes with fewer passes. It enhances workflow efficiency, reduces rework, and delivers reliable, repeatable results for professional shops and dedicated hobbyists working with hard materials and intricate geometries.
