Description

Widin Carbide End Mill, 4 Flute Square Edge Long Neck, 5 mm diameter x 25 mm overall length, is a precision cutting tool designed to machine high-hardened materials up to HRc70 with efficiency and reliability. Its long neck design provides the necessary clearance for workpieces with draft angles, extending the effective neck length to accommodate longer interference lengths without sacrificing rigidity or finish. Built for dry cutting and high-speed cutting, this end mill leverages a newly developed raw material and an advanced coating to deliver improved heat resistance, wear resistance, and overall performance. The ZSLNS20 construction is engineered to produce excellent workpiece finishes, helping you achieve high-quality surface results on challenging materials.

  • Long-neck design for draft-angle access: The extended neck length provides the necessary clearance to reach features with draft angles, reducing interference and enabling precise, consistent cuts across complex geometries.
  • Dry and high-speed cutting with advanced coating: A specially developed raw material and coating enable faster cutting, enhanced heat resistance, and improved wear protection for longer tool life in demanding applications.
  • Finish-focused ZSLNS20 for superior surfaces: Engineered to deliver excellent workpiece finishes, helping you achieve smooth, high-quality surfaces on difficult materials with fewer finishing passes.

Equipped to handle tough, high-hardness materials with repeatable precision, this end mill supports efficient workflows from roughing to finishing. Its combination of durability, access to tight features, and finish-oriented performance helps you reduce downtime, improve consistency, and complete projects with reliable, professional results.
