Product Introduction

The insert is mainly used for semi-finishing or finishing applications.

The diamond shape with a 35 degree top angle has the widest accessibility and provides the best surface finish when machining out of round.

With our proprietary coating, the insert is suitable for most materials.

Key Features

  • Shape: VCMT inserts feature a 35° rhombic (diamond) shape, giving them four cutting edges for cost-effectiveness. This narrower angle enhances strength at the cutting tip.
  • Positive Rake Angle: The cutting face slopes slightly forward from the cutting edge. This often produces a smoother cut with lower cutting forces, suitable for softer materials or low-power machines.
  • Clearance Angle: Typically 7° to help prevent rubbing against the workpiece.
  • Chipbreakers: VCMT inserts feature various chipbreaker geometries to control chip formation and flow.
  • Coatings: Often coated with materials like TiN, AlTiN, etc., to improve wear resistance and tool life.

VCMT insert Specification

Understanding the Insert Code

V: Shape. Rhombic (diamond) with a 80-degree included angle.
C: Clearance Angle. 7 degrees (positive).
M: Tolerance. Typically medium tolerance, but other options might be available.
T: Chipbreaker style & Hole Configuration. This letter identifies the specific chipbreaker geometry and hole presence/absence. 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.
