CNMG120404 AH120 Tungaloy — indexable insert for turning (ISO CNMG)

A CNMG120404 AH120 Tungaloy indexable insert engineered for external and internal turning, offering a wear- and break-resistant PVD-coated carbide grade that supports a sharp cutting edge and stable process security

• ISO CNMG geometry for standard toolholders
• AH120 PVD-coated carbide for wear resistance
• 0.4 mm corner radius for robust cutting edge
• Double-sided with cylindrical hole, 80° cutting angle

Consistent cutting performance through PVD-coated carbide

The PVD-coated AH120 grade provides a combination of wear resistance and edge stability that is particularly effective where a sharp cutting edge and predictable tool life are required. The PVD layer improves surface hardness and heat resistance while the cemented carbide substrate maintains toughness; together these properties reduce flank and crater wear under standard turning conditions, supporting fewer changeovers and more consistent part quality. Selecting this grade helps to limit unplanned downtime and contributes to predictable process cycles in series production.

Designed for flexible mounting and accurate positioning

Conformance with the ISO CNMG format ensures broad compatibility with established holders and boring bars; actual fit depends on form, relief angle, tolerance class, fastening method, size and thickness. The insert’s cylindrical hole and double-sided design allow straightforward clamping and economical usage, as both sides can be indexed. With a plate thickness of 4.76 mm and an inscribed circle of 12 mm, the geometry supports secure seating in modern clamping systems while the 0° clearance angle and 80° cutting angle balance strength and accessibility for both external and internal operations.

Improved chip control and robust edge life for reliable turning

The insert is equipped with a double-sided chipbreaker, optimised to control swarf formation during general turning tasks. A 0.4 mm corner radius provides a compromise between edge strength and the ability to produce accurate profiles and acceptable surface finishes. The rhombic plate shape contributes to accessibility in tight radii and internal features. For best results, pair the chipbreaker style and grade selection with the workpiece material and machine rigidity; this approach delivers repeatable results and reduces the likelihood of edge chipping in interrupted cuts.
