DNMG insert Meaning

Understanding the DNMG Insert Code

  • D: Shape: Rhombic (diamond) with a 55-degree included angle.
  • N: Clearance Angle: 0 degrees.
  • M: Tolerance: Medium tolerance is standard, though other precision tolerances may exist.
  • G: Chipbreaker style & Hole Configuration. This letter designates the specific chipbreaker geometry and whether the insert has a hole or not. Chipbreaker variations are numerous and manufacturer-specific.
  • Numerical Digits:
    • First Two Digits: Inscribed circle (IC) diameter in millimeters. To obtain the approximate inch equivalent, divide this number by 25.4.
    • Next Two Digits: Thickness in millimeters. Divide by 25.4 to convert to inches.
    • Last Two Digits: Nose radius in millimeters. To convert to inches, divide by 25.4.
