CNMG 120404 AH120 Tungaloy indexable insert for turning, PVD-coated carbide

CNMG 120404 AH120 Tungaloy indexable insert for precision external and internal turning applications, compatible with ISO-standard toolholders and designed for wear- and chip-resistant performance

• ISO-compatible rhombic insert CNMG 120404
• PVD-coated carbide AH120 for wear resistance
• Double-sided geometry with 0° clearance angle
• Cylindrical hole; 4.76 mm thickness; 12 mm size

Consistent cutting performance for turning operations

The PVD-coated AH120 grade is a carbide solution optimised for wear and chipping resistance in turning. The applied physical vapour deposition layer improves hot hardness and reduces flank wear, which in turn supports process security and longer cutting cycles. For practical use, this means a sharper initial cutting edge and predictable tool life under standard turning feeds and speeds; chip control is achieved by selecting the correct double-sided chipbreaker and matching it to the workpiece material.

Simple system integration and holder compatibility

As an ISO-series insert, the CNMG 120404 integrates into a wide range of standard external holders and boring bars; compatibility is determined by insert form, clearance angle, tolerance class, fixation style and plate thickness. The rhombic CNMG shape with a cylindrical hole permits secure clamping and quick indexing. The ISO designation 120404 indicates the insert geometry and size class, which assists in selecting a matching clamping set and replacement screws for a fast, repeatable setup on the shop floor.

Stable edge strength and surface quality with compact geometry

A corner radius of 0.4 mm balances edge strength and surface finish: the modest radius supports finer surface integrity while still providing resistance against micro-chipping. The plate thickness of 4.76 mm and the 80° approach angle contribute to stable cutting forces during external and internal turning operations. The zero-degree clearance angle suits specific holder geometries where a neutral rake is required; combined with the AH120 grade, the geometry promotes reliable chip formation and a consistent surface finish on common engineering materials.

FAQ

What materials is this insert suitable for?
The AH120 PVD-coated carbide grade is designed for wear-resistant turning and is suitable for a broad range of engineering materials when the correct chipbreaker and process parameters are chosen for the CNMG 120404.

How many usable cutting edges does the insert provide?
The CNMG 120404 is double-sided, offering two indexed cutting edges per side where applicable, depending on the holder and indexing practice.

Is the CNMG 120404 compatible with ISO holders?
Yes, the insert follows ISO-series geometry; compatibility depends on holder form, clearance angle, tolerance class, fixation and plate thickness.

What does the 0.4 mm corner radius affect in the process?
A 0.4 mm corner radius improves surface finish while preserving edge strength; it is a compromise between fine finishing and robustness against edge chipping.

How does the PVD coating influence cutting performance?
The PVD layer increases hot hardness and reduces adhesive wear, which extends tool life and supports consistent results in turning operations with the AH120 grade.
