CNMG 120404 AH8005 indexable turning insert (ISO CNMG 120404) — Tungaloy

The CNMG120404 AH8005 is an ISO‑standard indexable insert designed for external and internal turning, offering wear resistance for hard and heat‑resistant workpiece materials.

• PVD‑coated carbide grade AH8005
• 0.4 mm nose radius for fine finishing
• 80° rhombic insert, ISO CNMG form
• Double‑sided chipbreaker, cylindrical hole

Improved wear resistance for demanding materials

The PVD‑coated carbide grade AH8005 provides a wear‑resistant cutting edge that stands up to elevated temperatures and abrasive workpiece alloys. The PVD‑coated surface reduces flank wear and adhesion, which translates into longer periods between indexations and steady machining performance. For production turning where consistent surface finish and repeatability matter, this technical coating and substrate combination helps maintain dimensional accuracy and reduces scrap rates.

Cost‑effective geometry that supports finishing and light roughing

A double‑sided insert design combined with the 0.4 mm nose radius offers two usable cutting edges per indexation, lowering tooling costs and inventory turnover. The 80° rhombic form increases edge support and rigidity, improving stability in external and internal operations. The integrated chipbreaker promotes controlled chip formation for both light finishing passes and stable, small‑depth cuts, supporting predictable cycle times and fewer unplanned tool changes.

ISO compatibility and handling for efficient tool setup

The ISO CNMG 120404 designation ensures straightforward selection of compatible holders; compatibility is governed by form, clearance angle, tolerance class, clamping method, size and thickness. The insert features a cylindrical hole and a plate thickness of 4.76 mm with a plate size of 12 mm, enabling secure clamping in standard CNMG toolholders. For application support or to verify holder match and cutting data for a specific material, Metav Werkzeuge can provide cutting parameters and set‑up recommendations by email or phone.

FAQ

Which materials is this insert best suited to machine?
The CNMG120404 AH8005 insert from Tungaloy is formulated for heat‑resistant alloys and harder materials; the AH8005 PVD‑coated carbide grade offers improved wear resistance under elevated temperatures.

What are the primary applications for this insert?
Primarily intended for external and internal turning operations, the insert’s double‑sided geometry and chipbreaker make it suitable for light roughing and finishing in stable setups.

How does the double‑sided design affect tooling costs?
A double‑sided indexable insert provides two cutting edges per physical plate, halving the per‑edge cost compared with single‑sided alternatives and supporting longer intervals between reorders for items such as TUN6775756.

What must be considered when choosing a holder?
Holder compatibility with this ISO CNMG insert is defined by insert form, clearance angle, tolerance class, fastening method, size and thickness; the insert’s cylindrical hole and ISO geometry require a matching CNMG toolholder and clamping set.
