Widin Carbide End Mill - 4 Flute Tapered Neck For Finishing Mold & Die - 4mm x 2

The Widin Carbide End Mill is a precision finishing tool designed for mold and die machining. With a 4-flute design and a tapered neck, it delivers stable, accurate cuts and superior surface finishes in challenging materials. Engineered to machine high-hardened materials up to HRc70, it pairs a newly developed raw material with an ALTiN+HH coating to maximize performance in dry and high-speed cutting applications.

Whether you’re finishing mold cavities or delicate die features, the tapered neck and 4-flute geometry deliver consistent, chatter-free cutting and excellent chip control for repeatable results.

• Tapered Neck for Stability and Precision: The tapered neck reduces deflection and increases rigidity, helping you maintain tight tolerances in deep or narrow cavities and delivering consistent, dimensionally accurate cuts.
• 4-Flute Design for Finishing and Chip Evacuation: Optimized flute geometry provides a smooth surface finish and efficient chip removal, enabling steady feeds and reduced cycle times for high-quality finishes.
• Hard Material Capability with ALTiN+HH Coating: Capable of cutting hardened steels up to HRc70, with a wear-resistant ALTiN+HH coating that supports dry and high-speed cutting, extending tool life and reducing downtime.

This end mill helps you complete precise mold and die finishing tasks faster, with tighter tolerances and superior surface quality. The combination of a stable tapered neck, finishing-focused 4-flute geometry, and a durable ALTiN+HH coating translates to longer-lasting performance in demanding materials, fewer tool changes, and reliable results across high-speed dry-cut operations—so you can trust it to deliver consistent, professional results finish after finish.
