KNUX insert Meaning

Understanding the KNUX Insert Code

  • KNUX:

    • K: Shape (rhombic with an 55-degree included angle, although the edge has a unique preparation).
    • N: Clearance angle (0 degrees).
    • U: Indicates a higher strength design
    • X: Chipbreaker geometry and hole configuration (manufacturer-specific).
  • Numerical Digits

    • First Two Digits: Inscribed circle (IC) diameter in millimeters. Divide by 25.4 to get the approximate inch size.
    • Next Two Digits: Thickness in millimeters. Divide by 25.4 to convert to inches.
    • Last Two Digits: Corner radius in millimeters. Divide by 25.4 to convert to inches.
