Widin Carbide Corner Radius End Mill For Mold & Die - 4 Flute Multi Purpose - 4mm x70mm x R1

Widin Carbide Corner Radius End Mill for Mold & Die is a versatile 4-flute carbide cutting tool designed specifically for mold and die machining. With a 4 mm diameter and 70 mm overall length, it features a corner radius (R1) and a variable index geometry that promote aggressive material removal while preserving edge integrity.

The multi-purpose design handles a variety of materials and tasks, making it a reliable choice for mold cavities, cores, and precision finishing where consistent surface quality matters.

• 4-flute carbide design with optimized geometry: Delivers efficient chip evacuation and fast, smooth cuts, helping maintain sharp edges and better surface finishes even in tough materials.
• Variable index geometry for smoother cuts and longer tool life: Reduces vibration, distributes load more evenly, and allows stable performance across different materials and feed rates.
• Corner radius versatility for precise mold and die features: Available in multiple corner radii to match fillet needs and produce clean, concentric finishes in mold cavities and dies.

With this end mill, you can expect reliable, repeatable results that save time and reduce rework. The combination of carbide durability, 4-flute efficiency, and corner radius options helps you maintain tight tolerances, finish complex surfaces, and extend tool life in high-demand mold and die workflows. Whether you're prototyping or running high-volume production, this end mill supports faster setups, consistent finishes, and fewer tool changes, improving overall throughput and product quality.
