CNMG120416 AH120 indexable turning insert — PVD-coated carbide, rhombic 80° for turning (Tungaloy)

CNMG120416 AH120 is an ISO-standard indexable insert for general turning applications, designed for external and internal operations where a sharp cutting edge and reliable process security are required

• CNMG120416 AH120 turning insert, PVD-coated carbide
• Rhombic plate, 80° cutting angle, 1.6 mm radius
• Double-sided chipbreaker, cylindrical hole for clamping
• ISO-standard insert, 4.76 mm thickness

Higher throughput through a wear-resistant coating and robust carbide

The combination of a PVD-coated carbide grade and a stable substrate provides measurable improvements in tool life and edge integrity under continuous operation. The AH120 grade is specified as wear- and chipping-resistant, which translates into fewer interruptions for insert changes and more predictable cycle times on batch and single-part runs. For machining centres and turning lathes this means less downtime and a higher effective output per shift, while maintaining quality requirements for dimensional accuracy and repeatability.

Reduced setup complexity thanks to ISO conformity and standard geometry

Compatibility with toolholders is ensured by the ISO designation and the CNMG geometry: the insert’s form, 0° relief angle, tolerance class, fastening method, size and thickness determine fitment. The rhombic shape with an 80° cutting edge allows a wide spectrum of turning strategies with standard external holders or boring bars. This standardisation shortens setup and changeover times and simplifies stocking policies, as the insert fits many common ISO holders when the holder parameters match the insert geometry.

Consistent surface finish and reliable chip control from edge design

The 1.6 mm corner radius provides a balanced compromise between strength and edge definition: larger radii increase robustness, while smaller radii produce finer contours. Paired with a double-sided chipbreaker, the insert supports controlled chip formation across varying depths of cut and feeds, reducing the risk of entangling chips and improving surface integrity. The result is consistent component finish and fewer downstream quality checks, particularly beneficial when turning medium-duty steel and similar workpiece materials.

Practical handling, repeatable clamping and inventory advantages

The insert’s cylindrical hole supports secure clamping and repeatable location in the seat, making index changes quick and reliable. At a plate thickness of 4.76 mm and inscribed size of 12, the geometry is robust for general-purpose turning while remaining economical per cutting edge thanks to the double-sided design. The combination of ISO standard form and the PVD-coated grade simplifies procurement and tool management, allowing maintenance teams to keep smaller inventories while still covering a broad range of turning tasks.

FAQ

Is this insert suitable for both external and internal turning?
Yes. The CNMG120416 AH120 indexable turning insert is intended for external and internal turning operations and is effective when a sharp cutting edge and process security are required.

What are the main advantages of the AH120 PVD coating?
The AH120 PVD-coated grade on the CNMG120416 improves wear resistance and reduces the tendency to chip, delivering longer tool life and more reliable machining results in standard turning tasks.

How does the corner radius affect component finish?
The 1.6 mm corner radius offers a balance between edge strength and surface quality; it helps maintain a consistent finish while increasing resistance to edge fracture under interrupted cuts.

Will this insert fit common ISO holders?
The insert is ISO-standard CNMG; compatibility with a holder depends on matching the insert form, 0° relief angle, tolerance class, fastening and seat dimensions rather than brand alone.

What is the advantage of the cylindrical hole?
The cylindrical hole provides secure, repeatable clamping in the seat, facilitating fast index changes and reliable location for consistent cutting geometry.
