The Widin Carbide Corner Radius End Mill for Mold & Die is a precision cutting tool engineered for mold and die work, as well as general machining tasks. With a 3 mm diameter, 40 mm overall length, and a corner radius of R0.3, this 4-flute cutter features a tapered neck that boosts rigidity and stability for consistent, high-quality results across challenging profiles and deep grooves.

Designed to minimize chatter and tool deflection, it delivers smoother cutting and improved surface finishes. The tapered effective length further enhances rigidity, making it well-suited for deep groove machining. Available in multiple specifications, you can select the optimal length to match your project requirements, helping you optimize performance and extend tool life.

• 4-Flute design for smooth, consistent cutting: The 4-flute configuration reduces vibration and chatter, delivering cleaner edges and longer tool life.
• Tapered neck for increased rigidity and stability: The tapered geometry helps resist deflection, maintaining tight tolerances and better surface finishes in deep grooves.
• Corner Radius R0.3 optimized for mold & die work: The precise corner radius enables consistent fillets in molds and dies, improving part fit and reducing wear across production cycles.

This end mill helps you streamline workflow and achieve repeatable results. The combination of reduced chatter, consistent finishes, and a rugged tapered neck translates to fewer tool changes, less rework, and longer tool life—even on tough materials and precision molds. Whether you're machining intricate corners in dies or carving deep grooves, Widin's corner-radius design delivers dependable performance you can trust on every job.
