Description

OSG Carbide Centre Cutting End Mill Square Edge Long Length – 8mm diameter – is designed for aluminum machining. With centre-cutting capability and a square-edge tip, it plunges smoothly and produces clean pockets, even in deeper, harder-to-reach features. The extended length delivers greater reach without sacrificing cutting performance, making it ideal for machinists and fabricators working on complex aluminum parts.

  • Extended reach for tough-to-access features: The long-length design enables deeper pockets, through-holes, and intricate cavities, reducing the need for tool changes while maintaining efficient material removal and stable cutting in aluminum.
  • Centre-cutting, square-edge design for versatility and clean finishes: Centre-cutting geometry allows plunging and slotting, while the square edge delivers crisp bottoms and accurate profiles in aluminum parts, helping achieve consistent surface quality.
  • Carbide durability for repeatable performance: Hard carbide resists wear under aluminum machining, delivering long tool life and reliable, repeatable results across production runs.

This combination of reach, geometry, and carbide hardness helps you streamline workflows, reduce setup time, and produce high-quality aluminum components with fewer passes. It supports tight tolerances, smooth finishes, and dependable performance in demanding aluminum applications.
