DNMG 150412 AH120 turning insert — ISO turning insert, PVD-coated carbide, 55° — Tungaloy

DNMG150412 AH120 is an ISO‑standard indexable insert for turning, designed for stable machining where a sharp cutting edge and process security are required.

• ISO-standard DNMG geometry for wide holder fit
• PVD-coated carbide AH120 for wear resistance
• 55° rhombic shape for external and internal turning
• Double-sided chipbreaker; cylindrical hole for clamping

Consistent cutting performance for continuous turning

The PVD-coated carbide grade AH120 delivers a balance of wear resistance and edge stability that reduces the frequency of tool changes and supports uninterrupted production. As an indexable insert, it provides repeatable cutting geometry, which helps maintain component tolerances during longer production runs. The combination of a hard coating and a robust substrate means slower flank wear and more predictable maintenance intervals.

Secure mounting and broad holder compatibility

Designed to the ISO DNMG form, the insert features a 55° rhombic geometry, a cylindrical hole and a 0° clearance angle, ensuring compatibility with common external holders and boring bars. Compatibility is determined by form, free angle, tolerance class, clamping method, size and thickness; this insert’s standard dimensions simplify toolholder selection and help achieve consistent clamping force and repeatable seating, which in turn improves process reliability and reduces vibration-related wear.

Practical advantages of the chipbreaker and edge geometry

The double-sided chipbreaker provides dependable chip control across a range of engagement conditions, while the 1.2 mm nose radius balances strength and surface finish. A modest nose radius like this supports a stable cutting edge without compromising component quality. For operations that prioritise process security and a sharp cutting profile, the AH120 grade is formulated to resist chipping and edge breakdown, making it well suited to continuous and semi-continuous turning tasks.

Easy integration into existing turning systems

With an inscribed circle size of 15 mm and a plate thickness of 4.76 mm, the insert integrates into many ISO-compatible systems, enabling rapid changeovers and reduced setup time. The standardised form supports simplified inventory management: keeping a stock of these inserts can lower machine downtime and streamline tool supply chains. Selecting the appropriate chipbreaker and grade for the workpiece material ensures optimum performance and surface quality.

FAQ

What are the key benefits of the AH120 grade? The AH120 grade offers a PVD-coated carbide substrate that emphasises wear resistance and edge stability; Tungaloy’s AH120 is intended for applications requiring a sharp cutting edge and consistent process security.

Is the insert compatible with standard ISO holders? Yes. Compatibility depends on form, free angle, tolerance class, clamping, size and thickness; the DNMG geometry and cylindrical hole are designed for widespread ISO holder compatibility.

What is the nose radius and how does it affect the cut? The nose radius is 1.2 mm; this radius provides a compromise between a strong cutting edge and a good surface finish, helping to stabilise cuts while maintaining part quality.

Can this insert be used for both external and internal turning? Yes. The 55° rhombic form and double-sided chipbreaker make the insert suitable for both external and internal turning operations, provided the correct holder and process parameters are selected.

How is the insert fixed in the holder? The insert is secured via a cylindrical hole and appropriate clamping hardware; the double-sided design enables economical use of both cutting edges.
