Understanding the Designation: JDMT070204R

The alphanumeric code JDMT070204R follows ISO industry standards, providing essential insights into the insert’s geometry and design.

J – Indicates the insert shape (commonly referring to an 85° parallelogram design for specialized milling applications).

D – Stands for relief angle or clearance angle, typically 15°, which ensures optimized contact and reduces friction during cutting.

M – Represents the tolerance class, typically "M" meaning medium precision suitable for both finishing and general milling operations.

T – Describes the type of chipbreaker or cutting geometry, often optimized for chip evacuation in milling.

07 – The insert’s cutting edge length in millimeters (approx. 7 mm), compact yet effective for fine-to-medium milling.

02 – Denotes the insert thickness (approx. 2.4 mm), balancing rigidity with cutting sharpness.

04 – Specifies the corner radius (0.4 mm), ideal for achieving smoother surface finishes without excessive cutting forces.

R – Indicates right-hand cutting direction.

This nomenclature reveals that the JDMT070204R insert is engineered for precision milling, providing versatility across different operations.
