Description
The Widin Carbide Corner Radius End Mill is a high-performance cutting tool designed specifically for mold and die applications. With a 20 mm diameter, 100 mm length, four flutes, and carbide construction, it delivers efficient material removal and precise finishes in challenging molds and dies.
This multi-purpose end mill is built to handle a range of materials and tasks—from roughing pockets to finishing walls—while offering corner radius options (including R0.5) to match your cavity geometry. Its generous reach and robust shank make it a reliable choice for deep molds and intricate features.
- 4-Flute carbide design for efficient cutting: Four flutes provide strong material removal and stable cutting, improving chip evacuation and surface finish while reducing chatter.
- Corner radius versatility: Available in multiple radii (including R0.5) to match mold geometries, enabling precise corners and cleaner pocket walls.
- Long reach with rigid construction: 100 mm overall length with a sturdy shank minimizes deflection and maintains accuracy in deep cavities and demanding mold features.
Designed to streamline mold and die workflows, this end mill helps you complete precision features faster with fewer passes, consistent finishes, and reduced rework. The carbide geometry and chip-friendly design preserve tool life while delivering reliable performance across a range of materials, making it a dependable core tool for machinists, toolmakers, and shop floors focused on quality and efficiency.
