Description
The Widin Carbide Corner Radius End Mill is a precision cutting tool designed for mold and die machining. It features a 12 mm diameter, an 80 mm overall length, and a 0.3 mm corner radius. With a 45° helix angle and a four-flute design, it delivers aggressive material removal, strong edge stability, and efficient chip evacuation at high speeds.
Built for a wide range of materials and mold features, this end mill offers a variety of corner radius options, including R0.3, to match fillets and pockets and reduce tool changes. The robust carbide construction provides durability for repeated demanding cuts and long tool life.
- High-Feed, 45° Helix for Fast Material Removal: Optimized for high-feed rate applications, the 45° helix supports quick chip load and efficient evacuation, boosting productivity during aggressive cutting passes.
- 4 Flutes for Stability and Precision: The four-flute geometry increases rigidity and minimizes deflection, delivering consistent pocketing, finishing, and dimensional accuracy on tough materials.
- Versatile Corner Radius Options (including R0.3): A range of corner radii lets you tailor fillets and pockets to your part design, reducing tool changes and preserving corner integrity for reliable mold and die machining.
By combining fast, reliable material removal with predictable tool life and adaptability, this end mill helps you shorten cycle times, improve surface quality, and maintain steady production of molded parts. Its durable carbide construction and thoughtful geometry give you confidence to push for higher productivity without sacrificing precision.
