Widin Carbide Corner Radius End Mill For Mold & Die - 4 Flute High Feed Rate - 20mmx 100mm x R0.5

The Widin Carbide Corner Radius End Mill is a precision cutting tool designed specifically for mold and die work. With a 20 mm diameter and 100 mm overall length, this 4-flute carbide end mill features a 0.5 mm corner radius (R0.5) and a 45° helix. Its geometry is optimized for high feed rate milling, delivering aggressive material removal while maintaining control and a clear chip flow in demanding machining environments.

Built for a wide range of users—from engineers and shop floor professionals to hobbyists—the tool offers reliable performance in tough materials and complex cavities. The combination of four flutes, a sturdy carbide construction, and a versatile range of corner radii makes it a practical, durable choice for both roughing and finishing steps in mold and die applications.

• Optimized 45° helix for efficient chip evacuation: Designed to push chips away from the cutting edge quickly, reducing heat buildup and improving stability at high speeds for cleaner cuts and longer tool life.
• Four-flute rigidity for stable cutting: The 4-flute configuration provides enhanced rigidity and less deflection, delivering consistent hole and pocket sizes with better edge quality and finish.
• Versatile corner radius options (including 0.5 mm): A range of corner radii lets you match cavity geometry precisely, minimize secondary passes, and adapt to varying mold and die features without swapping tools.

Together, these features translate to faster material removal, fewer tool changes, and more predictable results in mold and die machining. The Widin end mill helps you boost productivity, maintain tighter tolerances, and achieve reliable, repeatable finishes across challenging projects.
