CNMG120408 AH110 Tungaloy indexable insert — ISO rhombic turning insert for general turning

CNMG120408 AH110 is an ISO‑standard rhombic indexable insert designed for external and internal turning applications, offering a balance of edge sharpness and process reliability.

• PVD‑coated carbide grade AH110
• ISO CNMG 120408 rhombic insert
• 0.8 mm corner radius for edge strength
• Double‑sided chipbreaker with cylindrical hole

Engineered for reliable turning performance

The CNMG120408 AH110 combines a PVD‑coated surface with a carbide substrate to provide enhanced wear resistance and stable cutting behaviour in turning operations. The AH110 grade is engineered to maintain a sharp cutting edge, reducing flank wear and supporting consistent machining results over longer tool life. These material and coating choices translate into measurable production benefits: fewer insert changes, more predictable cycle times and improved component quality under repeatable conditions. The emphasis on process security helps to reduce unplanned downtime on production lines and supports efficient machining across a variety of workpiece materials.

Designed for secure clamping and ISO compatibility

The insert’s ISO‑standard designation and rhombic geometry with an 80° included angle ensure compatibility with a wide range of ISO holders and turning tool systems. The cylindrical hole and standard dimensions permit reliable clamping when used with the correct external holder, underlay or clamping set and the recommended replacement screws. Compatibility is governed by form, relief angle, tolerance class, fastening method, size and thickness, so matching the insert to the correct holder is essential for stable cutting. The 0° relief angle and 4.76 mm body thickness contribute to stiffness at the cutting edge, which benefits operations where rigidity and repeatable positioning are required.

Operational advantages and selection guidance

Operational benefits stem from the double‑sided chipbreaker, the 0.8 mm corner radius and the insert’s overall stability. The chipbreaker supports controlled chip formation while the modest corner radius provides a compromise between edge strength and surface finish. With a plate thickness of 4.76 mm, the design enhances insert stability under moderate to heavy cutting forces. Selection advice: choose the chipbreaker variant and the AH110 grade when a combination of a sharp cutting edge and reliable, wear‑resistant performance is needed; select a larger corner radius or different chipbreaker for interrupted cuts or roughing where edge robustness is paramount. For assistance in matching insert geometry to specific materials and machine stability, the Metav Werkzeuge team can provide technical guidance and detailed compatibility checks.

FAQ

What materials is this insert suited for?
The AH110 grade and PVD‑coated carbide substrate are intended for a broad range of turning tasks; the insert performs well where a sharp cutting edge and reliable wear resistance are required.

How does the 0.8 mm corner radius affect performance?
A 0.8 mm corner radius increases edge strength and extends insert life while maintaining good surface finish for many finishing and semi‑finishing turning operations.

Which holder components are required for secure mounting?
Secure clamping needs a compatible ISO‑type external holder, an appropriate underlay or clamping set and the correct replacement screws matched to the CNMG120408 geometry.

Is this insert reversible or single‑use per cutting edge?
The CNMG120408 is double‑sided with a double‑sided chipbreaker, allowing multiple indexing positions before replacement is necessary.

What are the dimensional references to check before ordering?
Verify plate size 12 mm, thickness 4.76 mm, corner radius 0.8 mm and the 80° included angle against the holder specifications.
