Sidewinder High Performance End Mill for Titanium and Hardened Steel

This tool is a high-performance 7-flute square end mill engineered for titanium and hardened steel machining. Featuring a 40° helix angle, this tool delivers smoother cutting action, reduced vibration, and improved chip evacuation in demanding materials. Manufactured from premium solid carbide with an increased core diameter for added strength, the Sidewinder series is built for rigidity and stability under high-load conditions. The NACRO® coating enhances heat resistance, wear protection, and tool life, making it ideal for high-speed and high-efficiency CNC operations.

  • Increased core diameter for
  • additional strength
  • High performance grade of rod
  • nACRo coated for increased
  • tool life
  • Best for titanium, steel, stainless steel, and hardened steel
  • Good for nickel and iron
  • High-speed finishing operations
