DCGT insert Introduction
- D: Shape. Rhombic (diamond) with a 55-degree included angle.
- C: Clearance Angle. 7 degrees (positive).
- G: Tolerance. Medium (‘G’) is standard, though other precision tolerances exist.
- 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: Nose radius in millimeters. To convert to inches, divide by 25.4.
