Technical Specifications

The alphanumeric code on the insert conforms to ISO standard coding for indexable inserts,
providing the following specifications:

• DCGT: This is the insert shape designation.
  • D: 55° diamond shape.
  • C: 7° normal clearance angle.
  • G: Tolerance class (e.g., G-class for fine cutting).
  • T: Single-sided insert with a fixing hole and a chipbreaker on one side.
• 070202: This describes the physical dimensions.
  • 07: The length of the cutting edge is approximately 7 mm.
  • 02: The insert thickness is approximately 2.38 mm.
  • 02: The corner radius (nose radius, RE) is 0.2 mm
