CNMG 090402 AH120 – rhombic ISO turning insert for external and internal turning (PVD-coated carbide, 80°) by Tungaloy

The CNMG 090402 AH120 is an ISO rhombic turning insert designed for external and internal turning, offering a wear-resistant cutting edge that balances process security and sharpness for a wide range of turning tasks.

• PVD-coated carbide for high wear resistance
• Double-sided geometry for cost-effective use
• 0.2 mm corner radius for precise finishes
• ISO rhombic 80° form with cylindrical hole

Productive chip control for consistent cycle times

The indexable insert delivers predictable chip formation through its double-sided chipbreaker and PVD surface treatment. The AH120 grade, a PVD-coated carbide, is engineered to combine a durable cutting edge with reduced flank wear, which helps maintain cutting parameters over longer tool life. For shops running medium to heavy cutting conditions, this means fewer insert changes and steadier cycle times. The 80° rhombic geometry provides a robust cutting edge that is well suited to turning shoulders and general external operations while still enabling internal machining when holder accessibility permits.

Improved surface quality with a sharp, stable edge

A small corner radius of 0.2 mm delivers improved surface finishes on turned components without sacrificing edge stability. The insert’s PVD coating enhances wear resistance and reduces built-up edge tendencies on common steels and alloyed materials, promoting repeatable part quality. Where dimensional tolerance and surface integrity are critical, the controlled edge form and consistent chip evacuation of this insert support high-quality outputs, reducing rework and inspection iterations.

Clear compatibility and mounting for reliable setup

The ISO designation and standard dimensions facilitate selection of a matching external holder, clamping set and replacement screws. The insert is supplied with a cylindrical hole, ensuring secure fastening in compatible clamps and backplates; compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness. For practical workshop planning, the 4.76 mm plate thickness and size 09 format are typical values required when matching to toolholders. This clarity shortens setup times and reduces uncertainty in tool sourcing for production cells.

FAQ

What materials is this insert suitable for?
The CNMG 090402 AH120 insert, a PVD-coated carbide grade, is suitable for a broad range of turning applications; select the chipbreaker and grade AH120 for optimal performance with steels and alloyed materials according to machining stability.

How does the 0.2 mm radius affect finishing?
A 0.2 mm corner radius on the CNMG 090402 AH120 promotes finer surface finishes and improved dimensional control while retaining edge strength for general machining tasks.

Is the insert reversible and how many cutting edges are available?
The indexable CNMG090402 form is double-sided with two usable cutting edges per side, offering economical use before replacement is required.

Which holder features are required for correct clamping?
Secure clamping of the CNMG 090402 AH120 requires a compatible ISO rhombic holder matched for form, clearance angle, tolerance class, fastening method, size and plate thickness; the cylindrical hole ensures positive location in standard clamps.

Can the AH120 grade handle interrupted cuts?
The AH120 PVD-coated carbide grade is engineered for wear and fracture resistance; it is suitable for operations where a sharp cutting edge and process security are needed, including many interrupted cutting scenarios when combined with suitable cutting parameters.
