OSG 55° Helix Endmill Corner Radius - Centre Cutting Long Length - 8mm x R1

The OSG 55° Helix Endmill with a corner radius and long-length design is a versatile tool built for extensive milling, profiling, and slotting tasks. The 55-degree helix promotes efficient chip evacuation and reduces cutting forces, helping you maintain stable feeds and clean edges. With centre-cutting geometry and extended flute length, it’s well-suited for deep pockets and hard-to-reach features, delivering reliable performance across general machining applications for engineers, machinists, buyers, tradespeople, hobbyists, and fabricators alike.

• 55° Helix for Efficient Chip Evacuation: The 55-degree helix angle promotes fast chip evacuation and steadier cutting, helping maintain consistent finishes and reduce heat buildup across milling, profiling, and slotting tasks.
• Corner Radius for Smoother Edges: The corner radius design enables smoother cuts, minimizes tool marks on corners, and improves surface quality during profiling and slotting.
• Long Length with Center-Cutting Stability: Extended reach provides access to deep pockets and hard-to-reach features, while the center-cutting geometry preserves rigidity and cutting efficiency, reducing deflection and downtime.

Whether you're setting up a precision mill, profiling complex contours, or slotting across a series of pockets, this endmill helps you achieve consistent tool life and predictable results. The 8 mm diameter and R1 corner radius deliver smooth starts, clean edges, and reliable performance across a wide range of materials. Designed and manufactured by OSG, it supports dependable, repeatable results that help you reduce tool changes and boost throughput on everyday machining tasks.
