Description
The Widin Carbide Corner Radius End Mill is a versatile cutting tool designed specifically for mold and die manufacturing. With a 4-flute configuration and variable index geometry, it delivers smooth, consistent cuts and efficient chip evacuation across a broad range of materials and applications. This combination makes it a dependable choice for both setup-heavy mold work and high-precision die finishing.
Featuring an 8 mm diameter and an R2 corner radius, it maintains corner integrity while handling intricate features. The long shank design provides extended reach for deep grooves and pockets, helping you access challenging geometries without sacrificing rigidity or increasing setup time. This tool is built to perform reliably in demanding mold and die environments.
- Variable Index, 4-Flute Design: Optimizes cutting edge distribution to reduce cutting forces and improve chip evacuation, yielding smoother cuts and more stable tool life across a range of materials.
- Long Shank for Deep Grooves: Extended reach enables machining of deep pockets and complex cavities with fewer tool changes and maintained cutting performance.
- Flexible Corner Radius Options: Wide range of corner radii to match mold/die geometry, helping preserve fillets and reduce finishing passes for faster, cleaner results.
Whether you’re prototyping molds, refining die features, or producing complex components at scale, this end mill supports consistent performance, reduces downtime, and delivers reliable results. Its carbide construction offers durable wear resistance under demanding cutting conditions, while its geometry promotes efficient material removal and smooth, predictable milling in mold and die applications.
