CNMG 120408 AH110 rhombic turning insert by Tungaloy — PVD-coated carbide, 80° included angle

CNMG120408 AH110 is a compact, ISO-standard turning insert designed for reliable external and internal turning operations where a sharp cutting edge and stable chip formation are needed

• PVD-coated carbide grade AH110
• ISO CNMG120408 rhombic insert
• Double-sided chipbreaker for stable cuts
• Cylindrical-hole design for secure clamping

Precision machining with consistent wear resistance

The combination of a PVD coating and carbide substrate ensures reduced flank wear and improved edge stability under continuous cutting conditions. This indexable insert is optimised for operations that demand process security and repeatable results; the coating reduces adhesive wear while the substrate maintains edge strength. For manufacturers seeking predictable cycle times, the insert’s construction contributes to fewer tool changes and steadier component quality across batches.

ISO compatibility for straightforward toolholder integration

As an ISO-standardised CNMG insert, the geometry and dimensions follow established norms, simplifying holder selection and setup. The rhombic form with an 80° included angle and a cylindrical hole offers secure clamping and repeatable positioning in compatible external holders or boring bars. The relief angle of 0° and a plate thickness of 4.76 mm are decisive for stable axial support and correct seating; these measurable characteristics allow process engineers to match the insert to existing tool systems with confidence.

Shop-floor advantages: stability, economy, and handling

The double-sided chipbreaker design provides two usable cutting edges per indexation, extending service life and lowering running costs. Quick indexing reduces downtime and keeps machines productive, while the insert’s resistance to chipping supports higher feed rates when appropriate. Operational benefits include reduced inventory complexity—one insert covers a wide range of turning tasks—and improved operator confidence thanks to a reliable edge and predictable wear behaviour.

Guidance for selecting chipbreaker and materials

Choose the chipbreaker and the AH110 grade according to workpiece material and machining strategy: the chipbreaker type affects chip control and surface finish, while the AH110 grade is formulated for a combination of wear resistance and chipping avoidance. For users unfamiliar with the terms: PVD refers to a physical vapour deposition layer applied to the cutting edge to improve wear characteristics; carbide denotes a hard metal substrate that retains sharpness under cutting stresses. Match these properties to the material being machined and the stability of the setup for optimum results.

FAQ

What materials is this insert suitable for?
The AH110 grade indexable insert from Tungaloy is intended for general turning applications; the CNMG120408 AH110 demonstrates good wear resistance and chipping control suitable for a broad range of steels and alloyed materials when the correct chipbreaker is selected.

How many cutting edges are available per insert?
This rhombic insert features a double-sided chipbreaker, providing two usable cutting edges; each indexing yields a fresh edge to extend service life and improve cost efficiency.

How does the PVD coating benefit machining?
The PVD coating on the Tungaloy AH110 grade reduces adhesive wear and enhances edge retention, resulting in more consistent surface finish and longer tool life under typical turning conditions.

Which holders are compatible with this ISO insert?
Compatibility depends on holder form, clamping method, tolerance class, size and thickness; the CNMG120408 conforms to ISO dimensions, allowing use with compatible CNMG external holders and boring bars.
