Description
The Widin Carbide End Mill is a precision cutting tool designed for aluminium and non-ferrous alloys. With a 4 mm cutting diameter and a 20 mm flute length, it delivers high-performance machining and is available in long and extra-long lengths for extended reach into deep pockets and tight spaces.
Featuring a 45° helix, this end mill balances aggressive material removal with smooth, clean finishes, making it suitable for both production and hobbyist work.
- 3-Flute Design for Efficient Chip Evacuation: The three cutting edges create ample space for chips, reducing clogging and cutting forces to deliver smoother cuts and cleaner surfaces, even on soft metals.
- 45° Helix Optimized for Aluminium & Non-Ferrous: The 45-degree angle promotes effective chip curling and minimizes built-up edge, helping maintain consistent finishes and reducing feed-rate sensitivity.
- Extended Reach with Long & Extra-Long Lengths: Choose from long and extra-long versions to access deep pockets, undercuts, and hard-to-reach features without repositioning the workpiece, boosting productivity and reducing downtime.
Designed for reliability and versatile use, the Widin End Mill helps you achieve precise, repeatable results across aluminium and non-ferrous projects. Its carbide construction stands up to demanding cutting conditions, while the 3-flute geometry and 45° helix deliver consistent finishes, lower downtime, and easier workflow—from setup to final pass.
