Description

The OSG 55° Helix Endmill with a corner radius and long-length design is a versatile, high-performance cutting tool ideal for general milling tasks, profiling, and slotting. With a 6 mm diameter and a 0.5 mm corner radius, it delivers smooth starts and reliable results across a range of materials.

The 55-degree helix angle promotes efficient chip evacuation and reduces cutting forces, helping you maintain steady feeds and achieve consistent finishes even in deeper cuts. The extended reach design provides enhanced accessibility for challenging geometries without sacrificing cutting efficiency.

  • 55° Helix for Efficient Chip Evacuation: The 55° angle pulls chips away from the cut, reducing heat and cutting forces for smoother milling in profiling and slotting tasks.
  • Corner Radius for Smoother Cuts and Improved Finish: The 0.5 mm corner radius provides durable, consistent edges and reduces edge chipping on challenging profiles, improving surface finish with every pass.
  • Long-Length, Centre-Cutting Design for Depth and Flexibility: Extended flute length delivers reach for deep pockets and complex contours, while centre-cutting enables plunge milling from the workpiece surface.

With one tool that combines aggressive chip control, durable corners, and extended reach, you can reduce tool changes, shorten cycle times, and achieve consistent results across profiles and slots. The OSG endmill maintains stable performance from first cut to finish, helping improve dimensional accuracy and surface quality while simplifying setups and workflows.
