Widin Carbide End Mill - 4 Flute Square Edge Long Neck 3mm x 20mm

Widin Carbide End Mill – 4 Flute Square Edge Long Neck, 3mm x 20mm – is a high-performance milling tool designed to cut very hard materials with precision. Built for engineers, machinists, tradespeople, and serious hobbyists, it delivers reliable, consistent results on demanding workpieces.

Model ZSLNS20 features a long-neck geometry that provides ample clearance for draft-angle features and longer interference lengths, helping you avoid tool interference and maintain steady cutting depth. With a newly developed raw material and an advanced coating, this end mill supports dry cutting and high-speed operation, delivering improved heat resistance, wear resistance, and superior surface finishes on challenging materials up to HRc70.

• Long-neck access for draft-angle workpieces: The extended neck provides the clearance needed to reach deep features with draft angles, ensuring consistent cutting depth and reducing interference during milling.
• Dry-cutting and high-speed performance with advanced coating: A strengthened substrate and coating enable stable high-speed cuts, minimizing heat buildup and extending tool life in dry machining.
• Four-flute geometry for stable cuts and superb finishes: The 4-flute design promotes efficient chip evacuation and reduces vibration, delivering clean edges and high-quality surface finishes on hard materials up to HRc70.

This end mill helps you streamline workflows by delivering reliable cuts on hard materials, maintaining precision across draft-angle features, and enabling efficient dry, high-speed milling. Its durable construction and coating translate to longer tool life and consistent, repeatable results, making it a dependable choice for challenging materials and superior surface finishes.
