TCGT insert Meaning

Understanding the TCGT Insert Code

  • T: Shape: Trigon (triangle)
  • C: Clearance Angle: 7 degrees (positive)
  • G: Tolerance: Medium tolerance is standard, though other precision tolerances might be available.
  • T: 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: Corner radius in millimeters. To convert to inches, divide by 25.4.
