The Widin Carbide Corner Radius End Mill is a 4 mm diameter cutting tool designed for mold and die manufacturing. It combines a variable-index, 4-flute geometry with a long shank to handle deep grooves and tight corner radii with consistent, smooth cuts. It’s available with a range of corner radii, including R1, to match your exact mold geometry.

• Variable-Index Geometry: Optimizes edge distribution to reduce cutting forces and improve chip evacuation, delivering smoother cuts, longer tool life, and more predictable performance across challenging materials.
• 4-Flute Configuration: Provides added rigidity and efficient chip removal for stable finishes and reliable pocketing in mold and die work, while supporting a variety of corner radii for versatile applications.
• Long Shank for Deep Grooves: Extended reach lets you access deep cavities and tight pockets without repositioning, boosting productivity and reducing tool changes on complex parts.

This end mill helps you streamline mold-and-die workflows by delivering consistent finishes on complex radii and deep grooves. The carbide construction offers durability at typical speeds, while the combination of variable-index action and four-flute design minimizes downtime and maintenance, enabling faster setups and repeatable results from roughing to finishing.
