Description
Meet the OSG 55° Helix Endmill with a corner radius—the Centre-Cutting, regular-length tool crafted for versatile milling tasks. Sized at 10 mm in diameter with a 2 mm corner radius, it handles milling, profiling, and slotting with consistent precision and efficiency. The 55-degree helix enhances chip evacuation and lowers cutting forces, helping you maintain steady feeds and achieve clean, smooth surfaces across a range of materials.
- 55° Helix for efficient chip evacuation: The 55-degree helix angle promotes rapid chip clearance and reduces cutting forces, enabling higher feed rates and longer tool life for milling, profiling, and slotting.
- Corner Radius for smoother cuts and better finishes: The corner radius minimizes edge chipping, delivers chatter-free cuts, and improves surface finish on profiles and corners.
- Centre-Cutting, Regular-Length design for versatility and rigidity: Centre-cutting capability allows plunging and through-slot cutting, while the regular-length body provides balanced rigidity for reliable performance in general machining tasks.
This endmill is designed to deliver reliable, consistent results across a range of materials and applications. The combination of efficient chip evacuation, smoother finishes, and versatile cutting geometry helps reduce downtime, minimize rework, and speed up your workflow from setup to final pass. Trustworthy construction and durable materials make it a dependable choice for engineers, machinists, and hobbyists who demand precision and efficiency in everyday machining tasks.
