SLOW Helix

  • Specialized wiper flat geometry for improved finish
  • 3 flute design strengthens rigidity and improves wall finish
  • Specialized end geometry enhances bottom finish by reducing traditional circular marks
  • Slower helix (approx. 22°) reduces lifting forces, making design preferable for fiber-reinforced applications and vacuum table setups
  • Center cutting
  • Solid carbide
  • CNC ground in the USA
