Description
The OSG 55° Helix Endmill Square Edge, long-length and centre-cutting, is a versatile tool designed for general milling, profiling, and slotting tasks. Suitable for engineers, machinists, and hobbyists alike, it delivers precise, reliable performance across a wide range of applications. With a 55-degree helix, it promotes efficient chip evacuation and reduced cutting forces, while the extended length reaches deep pockets and challenging geometries without sacrificing cutting efficiency.
- 55° helix for efficient cutting and chip evacuation: The steep helix design enhances chip flow and reduces cutting resistance, helping you achieve smoother finishes and cooler operation.
- Long-length reach for deep pockets and hard-to-reach features: The extended length allows access to deep cavities and complex profiles in a single setup, improving workflow and reducing tool changes.
- Centre-cutting square-edge geometry for versatile milling: Enables precise plunging, slotting, and profiling with consistent edge quality across a range of materials for reliable, repeatable results.
This endmill supports streamlined workflows by enabling deeper access in fewer passes, delivering predictable performance and clean finishes on every cut. Its robust geometry provides dependable results for profiling, slotting, and milling tasks, making it a trusted choice for professional shops, on-site work, and hobbyist setups that demand accuracy and efficiency.
