CNMG120408 AH110 Tungaloy indexable insert for turning (rhombic, 80°)

CNMG120408 AH110 Tungaloy insert — an ISO-standard rhombic turning insert designed for reliable chip control and process security in general turning applications.

• ISO rhombic insert CNMG 120408
• PVD-coated AH110 carbide grade
• Double-sided chipbreaker for reliable chips
• Cylindrical hole and 80° cutting geometry

Reliable cutting performance for continuous production

The PVD-coated AH110 grade is engineered for wear- and chipping-resistant performance during turning operations. The combination of a carbide substrate with a PVD surface treatment reduces flank wear and preserves a sharp cutting edge, which supports consistent surface quality and longer tool life. The rhombic geometry with an 80° included angle provides a robust cutting stance for both external and internal turning, while the double-sided chipbreaker aids reliable chip formation under varying feed and depth conditions. This balance of edge stability and chip control translates into fewer interruptions and steadier cycle times on production runs.

Fast integration and secure clamping in existing tool systems

Compatibility is governed by form, clearance angle, tolerance class, fastening method, size and thickness — all standardised to fit ISO tooling systems. The insert’s cylindrical hole and specified sit dimensions simplify mounting in matching external holders or boring bars, while the 4.76 mm thickness and rhombic shape ensure correct seating and clamping. Clear specification of the 0° clearance and a 0.8 mm corner radius helps to predict cutting behaviour and set-up parameters. For workshops, this means reduced set-up time and straightforward replacement procedures when used in concert with the appropriate shim or locking set and replacement screws.

Practical selection advice and application scope

This insert is intended for turning tasks where a combination of a precise cutting edge and process reliability is required. Typical use includes both external and internal turning; choose the chipbreaker style and grade in relation to workpiece stability and machining strategy. The product’s ISO standardisation makes it suitable for integration into established turning tool systems; the CNMG120408 designation identifies the plate geometry and size for quick cross-referencing. When machining operations demand consistent results and controlled chips rather than maximal material removal rates, this indexable insert provides a measured compromise between robustness and edge definition.

FAQ

What turning operations is this insert suited for?
The insert is suitable for external and internal turning; the CNMG120408 AH110 Tungaloy insert is optimised where a sharp cutting edge and process security are both required.

How is compatibility with a holder determined?
Compatibility depends on form, clearance angle, tolerance class, fastening method, size and thickness; check the CNMG120408 dimensions and mounting style against the intended holder.

What benefits does the AH110 grade provide?
The AH110 PVD-coated carbide grade offers improved wear resistance and chipping protection, supporting a stable cutting edge and consistent surface finish in turning.

What are the critical dimensions to consider at set-up?
Pay attention to the plate size (12 mm), thickness (4.76 mm), included angle (80°), clearance angle (0°) and corner radius (0.8 mm) for correct seating and expected cutting behaviour.
