CNMG120404 AH110 – Turning insert, PVD-coated carbide by Tungaloy

The CNMG120404 AH110 is an ISO rhombic turning insert designed for reliable external and internal turning, offering a sharp, wear-resistant cutting edge and process-secure performance.

• PVD-coated carbide AH110 grade
• ISO CNMG 120404 rhombic shape
• 0.4 mm corner radius for consistent finishes
• Double-sided chipbreaker, with cylindrical hole

Longer tool life through engineered coating and substrate

The insert uses a PVD-coated carbide substrate in the AH110 grade, which delivers a balance of wear resistance and toughness. The PVD coating adheres firmly to the tungsten-carbide base, reducing flank and crater wear and therefore extending effective tool life; this results in fewer interruptions for insert changes and more consistent cycle times. For turning shops seeking predictable economics, this engineered combination reduces variable tooling costs while maintaining edge integrity where a sharp cutting edge is required.

Geometry designed for precise clamping and reproducible results

The rhombic ISO form with designation CNMG120404 is optimised for secure seating in standard holders; key dimensions such as the 12 mm inscribed circle, 4.76 mm plate thickness and 0.4 mm corner radius ensure a stable cutting position. Compatibility is determined by form, clearance angle, tolerance class, fastening style, size and thickness — here the 0° clearance angle and cylindrical hole facilitate repeatable clamping and straightforward replacement in compatible external holders or boring bars. This geometry supports consistent radial positioning, which in turn improves repeatability and surface quality between insert changes.

Reliable chip control and versatile turning performance

Equipped with a double-sided chipbreaker, the insert offers effective chip control across a range of turning operations; the two usable sides double the service life per index and help to maintain consistent cutting forces. The grade is described as wear- and fracture-resistant and is recommended when both a sharp cutting edge and high process security are demanded. Typical applications include external and internal turning where controlled chip formation and stable cutting edge behaviour improve productivity and surface finish. If the exact workpiece material or machining strategy requires fine-tuning, technical advisers can recommend the optimal chipbreaker and cutting data to match the machining context.

FAQ

What holders are compatible with this insert?
Compatibility depends on form, clearance angle, tolerance class, fastening, size and thickness; the CNMG120404 AH110 fits holders designed for ISO CNMG 120404 dimensions and a 12 mm inscribed circle.

Which materials is this grade suitable for?
The AH110 PVD-coated carbide grade is a wear- and fracture-resistant choice for turning tasks that require a sharp cutting edge and process security; suitability should be verified against the specific workpiece material.

Is the insert indexable and how many usable edges are there?
The insert is double-sided with a chipbreaker on both faces, providing two usable cutting edges per side and therefore extended service life through indexing.

What corner radius and thickness does the insert have?
The insert has a 0.4 mm corner radius and a plate thickness of 4.76 mm, supporting consistent surface finish and stable clamping.

Are there any special mounting features to note?
The insert features a cylindrical hole for fastening and is manufactured to ISO CNMG 120404 dimensions to ensure reproducible clamping in compatible holders.
