The Widin Carbide Corner Radius End Mill for Mold & Die is a precision cutting tool designed for mold and die applications. With a 4 mm diameter and 40 mm overall length, this 2-flute end mill features a tapered neck to reduce cutting forces, minimize chatter, and deliver stable, accurate cuts in deep groove profiles.

Crafted from solid carbide, it maintains sharpness and rigidity under demanding use, helping you achieve consistent edge quality and long tool life even in tough mold materials.

• Tapered neck for enhanced rigidity: The engineered taper increases stiffness in the cutting zone, reducing deflection and chatter during deep groove machining for smoother, more reliable performance.
• Corner radius of R0.5 for durable, smooth corners: The 0.5 mm radius protects corners from chipping and yields consistent radii on mold and die features, improving part integrity and finish.
• 2-flute design with efficient chip evacuation: Fewer flutes with optimized geometry deliver strong cutting action, improved chip clearance, and smoother cuts—helping you achieve faster feeds and a cleaner surface finish.

This end mill supports a more efficient mold-and-die workflow: predictable radii, tighter tolerances, and reliable tool life translate to less rework and downtime. The combination of rigidity, precise corner geometry, and easy chip removal helps you finish cavities and channels with clean walls, improved surface quality, and consistent results across batches. Ideal for deep groove work, it enables you to push faster feeds without sacrificing precision, boosting overall productivity.
