Widin Carbide Corner Radius End Mill for Mold & Die is a precision cutting tool designed for mold and die work. Its 4-flute configuration and tapered neck reduce cutting forces and chatter, delivering smoother cuts and improved surface finishes.

With a 4 mm diameter, 70 mm overall length, and a 0.3 mm corner radius, this end mill provides the reach you need without sacrificing rigidity. The tapered effective length boosts stability and rigidity during cutting, making it particularly well-suited for deep groove work. It is available in several specifications to help you pick the exact length and geometry for your machining project.

• 4-flute configuration for smooth, stable cutting: Balances cutting forces and improves chip evacuation to minimize chatter, yielding cleaner surfaces and more consistent results.
• Tapered neck for enhanced rigidity: Increases stability along the cutting length, delivering precise contours in deep grooves and reducing tool deflection during heavy cuts.
• Corner radius of 0.3 mm for precise mold/die corners: Starts and finishes rounded edges consistently, improves edge quality, and extends tool life by distributing cutting loads more evenly.

This Widin end mill helps you streamline mold and die fabrication with dependable performance, steadier feeds, and repeatable results. By combining rigidity, controlled geometry, and a useful range of specifications, it supports faster setups, reduced rework, and longer tool life—producing accurate corners, smooth finishes, and durable tooling for demanding applications.
