Widin Carbide End Mill - 4 Flute Square Edge Long Neck 4mm x 50mm

The Widin Carbide End Mill is a precision 4‑flute, square‑edge cutting tool designed for demanding materials. With a 4 mm diameter and a 50 mm length, it’s engineered to machine high-hardened alloys up to HRc70 with clean, reliable results. Its long‑neck design provides added reach for draft-angle workpieces, supplying the necessary interference length to access recessed features without sacrificing rigidity.

Built for speed and endurance, this end mill leverages a newly developed raw material and an advanced coating to enable dry cutting and high‑speed operation. The result is superior heat and wear resistance, steadier performance, and extended tool life. The ZSLNS20 coating is specifically engineered to deliver excellent workpiece finishes, helping you achieve smooth, consistent surfaces even on tough materials.

• Extended long‑neck reach for draft angles: Provides the interference length needed to access angled or drafted features, reducing interference and improving accessibility without sacrificing rigidity.
• 4‑flute square edge for stable, clean cuts: Four flutes offer strong rigidity and efficient chip evacuation, helping deliver consistent dimensions and high-quality surface finishes.
• Dry/high‑speed cutting with advanced coating: Crafted from advanced materials and coated for heat and wear resistance, enabling faster cycles and longer tool life on hard materials up to HRc70.

This end mill is a reliable choice for engineers, machinists, and hobbyists who demand precise finishes on hardened workpieces. It supports efficient production workflows, reduces downtime from tool changes, and consistently delivers high-quality surfaces—making it well-suited for challenging jobs where draft angles and hard alloys are part of the brief.
