SCGX insert specification

SCGX insert is the specialist in external turning. The function of a chip breaker is to improve chip control and to reduce cutting resistance.

A better balance between the two will increase the machining performance.

If chips can be broken into suitable lengths by the chip breaker, they will not wrap around the workpiece, vibration will decrease and tools will not be so easily damaged.

Chip breakers also affect cutting resistance.

Reduced cutting resistance can avoid chipping and fracturing of the cutting edge caused by vibration.

Additionally, lower cutting resistance can decrease the load and heat, and can delay the development of tool wear.

Understanding the SCGX Insert Code

  • S: Shape: Square
  • C: Clearance Angle: 7 degrees (positive)
  • G: Tolerance: Medium tolerance is standard, though other precision tolerances might be available.
  • X: Chipbreaker style & Hole Configuration. This letter designates the specific chipbreaker geometry and whether the insert has a hole or not. 
  • 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.
