The Widin Carbide Corner Radius End Mill is a precision cutting tool designed for mold and die work. With a 3 mm diameter, 20 mm length, and a corner radius of R0.2, this 4-flute end mill balances rigidity with a fine cutting edge to produce accurate profiles and smooth surfaces.

• 4-Flute Design for Stable, Finely Finished Cuts: The 4-flute configuration increases rigidity and improves chip evacuation, delivering cleaner surfaces and longer tool life in mold and die applications.
• Tapered Neck for Enhanced Rigidity in Deep Grooves: The tapered neck design boosts stiffness and reduces deflection, enabling precise deep-groove machining and consistent depths even in demanding materials.
• Corner Radius of R0.2 for Precise Mold & Die Edges: A 0.2 mm corner radius preserves sharp internal corners while resisting chipping, improving edge strength and surface finish in cavities.

This end mill helps you achieve repeatable tool life, faster cycle times, and high-precision results across mold and die cavities. Its combination of carbide construction and optimized geometry provides reliable performance in challenging materials, reducing the need for rework and enabling cleaner, more consistent finishes on every part.
