DCGX insert Introduction

Understanding the DCGX Insert Code

- - D: Shape: Rhombic (diamond) with a 55-degree included angle.
  - C: Clearance Angle: 7 degrees (positive).
  - G: Tolerance: “G” indicates a medium tolerance range, though other precision tolerances may exist.
  - X: 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.
