Description
The Widin Carbide End Mill is a precision cutting tool designed for challenging machining tasks. With a ball nose tip, a 2 mm diameter, and 50 mm overall length, it’s ideal for engineers, fabricators, and hobbyists who need accurate contouring and reliable performance. The tapered neck helps maintain smooth, stable cuts even in demanding applications like deep grooves and sloped surfaces.
- Tapered neck for smoother, more stable cuts: Reduces tool vibration and chatter, enabling consistent finishes on challenging profiles and deep features without sacrificing performance.
- Ball nose geometry with 3-flute design: Delivers precise radii on contoured surfaces while improving chip evacuation for a cleaner, more accurate final part.
- Designed for hard materials with advanced coating: Capable of machining up to HRc70 with dry or high-speed cutting, delivering longer tool life and dependable results in tough environments.
This end mill is built to enhance your workflow by cutting harder materials more efficiently, reducing rework, and producing reliable, repeatable finishes on complex geometries. The combination of a robust carbide core, optimized coating, and neck geometry supports faster speeds, fewer passes, and improved surface quality across a range of applications—from precision prototyping to high‑demand production tasks.
