The WidIn Carbide Corner Radius End Mill for Mold & Die is a precision tool designed for mold makers, engineers, and machinists who require clean radii and consistent performance. With a 4 mm cutting diameter, 70 mm overall length, a 0.2 mm corner radius (R0.2), and a 2-flute, tapered neck configuration, this end mill delivers smooth cuts and stable operation in deep grooves and complex cavities.

Its tapered neck increases rigidity where it matters most, reducing vibration and tool deflection for precise geometry during deep groove machining. Combined with carbide construction, the geometry supports reliable results across a range of mold and die materials, and WidIn offers this tool in multiple specifications to fit different project needs.

• Corner Radius for Cleaner Edges: The 0.2 mm radius creates gentle fillets in corners and grooves, reducing stress concentrations and delivering smoother radii for better mold and die finish.
• Tapered Neck for Stability and Deep Groove Performance: The tapered effective length lowers cutting forces and deflection, boosting rigidity for stable, accurate cuts in deep grooves and long-reach operations.
• 2-Flute Carbide with Flexible Specifications: Two flutes enable efficient chip evacuation and smooth cutting, while carbide construction provides durable performance across a range of materials; available in multiple specifications to match different machining needs.

This combination of geometry and material science translates to faster, more predictable milling of molds and dies. You’ll achieve consistent corner radii and surface finishes, reduce rework, and experience steadier feeds with fewer tool changes. Rely on reliable performance across jobs, with a tool designed to endure the demands of precision mold and die machining.
