OSG 55° Helix Endmill Corner Radius - Centre Cutting Long Length - 12mm x R1

The OSG 55° Helix Endmill features a 12 mm diameter with a 1 mm corner radius (R1) and a long-length design, delivering extended reach for deep pockets and tall features. Its 55-degree helix promotes efficient chip evacuation and reduced cutting forces, making it well-suited for milling, profiling, and slotting tasks. This centre-cutting tool is designed for general machining across a range of applications, providing reliable results even in tight or challenging setups.

• 55° Helix for Efficient Chip Evacuation: The 55-degree angle channels chips away from the cutting edge, helping maintain cutting efficiency, reduce heat buildup, and improve surface finish during milling, profiling, and slotting.
• Corner Radius for Smoother, Stronger Cuts: The R1 corner radius supports cleaner radii, enhances edge durability, and reduces chipping in profiling and slotting work while delivering a smoother final surface.
• Long-Length, Centre-Cutting Design for Extended Reach: The extended flute length and full plunge capability enable access to deep pockets and tall features without compromising rigidity or stability during cuts.

Together, these features translate to faster material removal, cleaner edges, and consistent performance across multiple materials and setups. The combination of a 55° helix, corner radius, and long reach helps streamline workflows, reduce tool changes, and maintain reliable results from the first cut to the last.
