The Widin Carbide Corner Radius End Mill is a purpose-built cutting tool for mold and die manufacturing. With a 16 mm diameter and a corner radius of R2, plus a long shank for extended reach, it handles deep grooves and tight pockets with confidence. It supports a wide range of corner radii to match your part geometry, helping you achieve precise fillets and smooth finishes across different molds.

Designed for excellent machinability, the end mill uses a variable index and 4-flute configuration to optimize cutting edge distribution. This reduces cutting forces, improves chip evacuation, and delivers smoother, more efficient machining operations—even on challenging mold and die features.

• Variable index geometry: Distributes cutting edges to minimize vibration and cutting forces, delivering smoother cuts and easier chip evacuation for consistent performance across complex mold surfaces.
• 4-flute design with optimized chip evacuation: Balances aggressive material removal with stable cutting, enhancing throughput and reducing downtime during longer runs.
• Long shank for deep grooves: Provides extended reach into tight pockets and deep slots without sacrificing rigidity, enabling precise features in mold and die work.

In practice, this end mill helps you achieve accurate corner radii and reliable stock removal with fewer tool changes and less rework. The combination of variable index geometry and a long shank translates to predictable, repeatable results across batches, making it a dependable choice for professional shops and dedicated hobbyists alike.
