Description

The OSG Carbide Rocket End Mill Square Edge with Long Length is a general-purpose carbide milling tool built to handle a wide range of tasks—from milling and slotting to profiling. Its extended length provides extra reach for deep cavities, through-holes, and hard-to-access features, helping you complete jobs without retooling.

Engineered for dependable performance in everyday machining, this 12mm end mill features a square-edge geometry that suits many materials and setups. Its robust carbide construction delivers consistent cuts, supports long tool life, and maintains precision in busy shop environments.

  • Extended reach for hard-to-access areas: Access deep slots, pockets, and tight passages without repositioning the workpiece, reducing setup time and improving accuracy.
  • Square-edge versatility for milling, slotting, and profiling: Perform multiple operations with one tool—trimming edges, creating slots, and shaping contours in a single setup.
  • Durable carbide construction for reliable performance: Hard, wear-resistant carbide delivers steady cutting forces, long tool life, and consistent results across a range of general machining tasks.

This end mill helps streamline workflows by reducing tool changes and enabling repeatable, high-quality finishes. With trusted OSG engineering, you can rely on predictable performance, minimize downtime, and complete general machining projects efficiently—whether in a professional shop or a DIY workshop.
