Description

The OSG 55° Helix Endmill with a corner radius and long-length design is a versatile tool built for a wide range of machining tasks. It’s ideal for engineers, buyers, tradespeople, hobbyists, and general machining environments that need reliable performance in milling, profiling, and slotting. The 55° helix promotes efficient chip evacuation and reduces cutting forces, while the corner radius supports smoother cuts and improved surface finishes, even in deep pockets or tight radii.

  • 55° Helix for Efficient Chip Evacuation: The steeper helix geometry channels chips away quickly, reducing cutting resistance and promoting smoother cutting across a variety of materials.
  • Corner Radius R0.3 for Smoother Finishes: The built-in corner radius softens sharp corners, delivering cleaner edges and better surface quality on complex profiles.
  • Long Length Centre-Cutting Design for Deep Reach: Extended reach and center-cutting capability let you mill deep pockets, profiles, and slots without repositioning the tool.

Designed to deliver consistent results across common machining tasks, this 6 mm endmill combines extended reach with reliable geometry to tackle profiling, slotting, and contouring in a single setup. The tool’s rugged construction and precise tolerances help you maintain accuracy, reduce rework, and keep a steady workflow from setup to finish.
