The Widin Carbide Corner Radius End Mill is a high-performance cutting tool designed for mold and die machining. With a 4 mm diameter and 40 mm overall length, this end mill features a long shank and four flutes to deliver stable, precise corners in challenging cavities. Its variable index geometry promotes efficient chip evacuation and reduces cutting forces, helping you achieve smoother surfaces and faster cycle times. Available with various corner radius sizes, it supports tailored machining for diverse mold and die features and excels in deep-pocket operations thanks to its extended reach.

• Variable index geometry for smoother, more efficient cuts: Distributes cutting edges to reduce load on the tool, improving chip evacuation and surface finish while delivering steadier, consistent performance during mold and die work.
• Corner radius versatility for precise mold and die finishes: Multiple corner radii let you tailor profiles to match cavity geometry, enabling sharp corners where needed and smooth transitions elsewhere.
• Long shank design for deep pockets and stable milling: Extended reach provides access to deep grooves and complex features with improved rigidity and predictable results in challenging setups.

This end mill helps you streamline mold and die workflows by enabling precise cornering across complex cavities, reducing rework, and improving throughput. The combination of a rigid long-shank design, reliable chip evacuation, and adaptable corner radii supports consistent, high-quality finishes and dependable performance across demanding applications.
