RCMT insert Meaning

Understanding the RCMT Insert Code

  • R: Shape: Round. RCMT inserts are round but have cutting edges spaced around the circumference for indexing.
  • C: Clearance Angle: 0 degrees, though some variations might exist with a small positive angle.
  • M: Tolerance: Medium tolerance (‘M’) is most typical, but precision tolerances might be available.
  • T: Chipbreaker style & Hole Configuration. This letter denotes the specific chipbreaker and whether the insert has a hole. 
  • 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: May refer to thickness or other dimensions depending on the manufacturer. Always consult the specific manufacturer’s catalog.

Example: RCMT 1204MO

    • Round shape: with multiple cutting edges.
    • 0-degree clearance angle (or potentially a slight positive angle)
    • Medium tolerance.
    • Manufacturer-specific chipbreaker and hole configuration.
    • 12mm inscribed circle diameter (approx. 0.47″ in inches)
    • “04” and “MO” will have manufacturer-specific meanings for thickness, edge style, etc.

    Important Notes

    • Manufacturer Specificity: Due to the round shape, dimensions like thickness and specific edge geometry will be heavily dependent on the individual manufacturer’s design. The numerical part of the code beyond the IC is not standardized.
    • Chipbreaker Styles: Consult the manufacturer’s catalog for details on specific chipbreaker geometries and functions.
    • Versatile Shape: Round inserts offer multiple cutting edges which can be indexed for cost-effectiveness.
