DCMT 070202 AH120 Tungaloy – Indexable turning insert, PVD-coated carbide

The DCMT070202 AH120 is an ISO-standard indexable turning insert engineered for external and internal turning where a sharp cutting edge and process security are required.

• ISO rhombic insert DCMT 07 form
• PVD-coated carbide for high wear resistance
• 0.2 mm corner radius for precise finishes
• Cylindrical hole with 40°–60° countersink

Consistent cutting performance through robust coating and grade

The AH120 grade combines a PVD-coated surface with a wear- and chip-resistant carbide substrate to deliver long tool life and stable cutting behaviour. The protective coating reduces abrasive wear and improves resistance to built-up edge formation, which supports consistent component tolerances across production runs. For machining operations that demand a reliable cutting edge and steady process control, this combination reduces unplanned tool changes and contributes to improved productivity.

Geometry engineered for repeatable surface quality

The insert’s rhomboid geometry with a nominal 55° lead angle and a 0.2 mm corner radius provides a balance between robustness and finish capability. The 7° relief angle ensures secure seating in typical ISO holders while enabling effective chip formation. The plate thickness of 2.38 mm and size 07 maintain mechanical rigidity for stable cutting, and the cylindrical hole with one-sided countersink (40°–60°) permits correct clamping and orientation in compatible toolholders. These geometric elements together help produce consistent surface finishes and predictable tool behaviour even when switching between similar workpieces or machines.

Practical selection and system compatibility for turning tasks

Designed as a component of an ISO insert system, the package requires a compatible external holder or boring bar plus the appropriate backing/clamp set and replacement screws. Compatibility is determined by insert form, relief angle, tolerance class, fastening method, size and thickness; verify the holder matches the ISO DCMT form and the specified clamping style. The single-sided chipbreaker is suitable for general turning operations where a controlled chip flow is preferred; select the chipbreaker and grade according to the workpiece material, cut type and machining stability to achieve the best balance of tool life and part quality.

For robust, process-secure turning, specify the Tungaloy AH120 DCMT070202 insert and contact Metav Werkzeuge for availability and application guidance.

FAQ

What work is the DCMT070202 AH120 insert intended for? The DCMT070202 AH120 indexable turning insert from Tungaloy is intended for external and internal turning where a sharp cutting edge and process security are priorities.

How does the AH120 grade affect tool life? The AH120 PVD-coated carbide grade increases wear resistance and reduces chipping, so the DCMT070202 AH120 insert maintains cutting-edge integrity for extended runtimes.

Which holders are compatible with this insert? Compatibility depends on insert form, relief angle, tolerance class, fastening method, size and thickness; the DCMT070202 requires a holder compatible with ISO rhombic DCMT 07 geometry and the specified clamping style.

What does the 0.2 mm corner radius mean for surface finish? A 0.2 mm corner radius on the DCMT070202 AH120 creates a compromise between edge strength and the ability to achieve finer surface finishes, making it suitable for many standard finishing and semi-finishing operations.

Is the insert supplied with screws or clamps? The DCMT070202 AH120 is supplied as the insert itself; system components such as the matching external holder, backing/clamp set and replacement screws are part of the complete tooling setup and should be sourced separately.
