SCMT insert

SCMT insert angle: 90° Square ,7° Positive Rake Insert with single-sided chipbreaker;

Screw-On Inserts;

High Polish SquareTurning Insert for wide range of materials;

Square carbide insert;

Breaker Application: Semi-finishing & Finishing machining;

Matching TurningTool Holder: SSDCN,SSKCR/L;

SCMT Insert can deal with multiple operations by combining different chip breakers and grades;

Material : Tungsten Carbide;


SCMT inserts excel in external turning.

Their integrated chip breakers optimize chip control and reduce cutting resistance for superior machining performance.

Ideal chip formation prevents workpiece damage, minimizes vibration, and extends tool life.

Reduced cutting resistance also decreases load and heat generation, further protecting your tooling investment.

SCMT insert Meaning

Understanding the SCMT Insert Code

  • S: Shape: Square
  • C: Clearance Angle: 7 degrees
  • M: 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.
