Description

The OSG 55° Helix Endmill Square Edge is a long-length milling tool designed for professionals who need precision and extended reach. With a 16 mm diameter and a 55-degree helix, it delivers efficient chip evacuation and lower cutting forces for milling, profiling, and slotting tasks.

Its extended length provides access to deep pockets and challenging workpieces without sacrificing cutting performance. The square edge and centre-cutting geometry support plunge milling and versatile operation in general machining, ensuring consistent, high-quality results across a range of applications.

  • 55° Helix for Efficient Chip Evacuation: The steep helix guides chips away from the cut, reducing heat buildup and promoting smoother cutting and longer tool life.
  • Long-Length Design for Deep Access: The extended length lets you reach deep pockets, slots, and complex geometries without repositioning or sacrificing rigidity, improving throughput.
  • Centre-Cutting Square Edge for Plunge Milling: Center-cutting geometry enables plunging and a wide range of milling tasks, profiling, and slotting with a single tool, delivering consistent results.

With the OSG 55° Helix Endmill, you get reliable, repeatable performance across general machining jobs. The combination of high-helix geometry, long reach, and robust square-edge design minimizes tool changes, reduces cycle times in deep-pocket work, and helps achieve precise finishes on challenging parts. Built for consistent results in production or hobbyist settings, this endmill is a dependable choice when extended reach and dependable performance matter.
