DNMG110412 AH120 Tungaloy turning insert — PVD-coated carbide, 55° geometry

DNMG110412 AH120 is an ISO-format indexable insert engineered for external and internal turning where a sharp edge and process security are required

• PVD-coated carbide for wear resistance
• 55° rhomboid geometry for versatile turning
• Double-sided chipbreaker for stable chip control
• Corner radius 1.2 mm for balanced edge strength

Consistent cutting performance through PVD-coated carbide

The AH120 grade combines a PVD coating with a robust carbide substrate to deliver a wear- and chipping-resistant cutting edge. This construction extends tool life under demanding turning conditions and supports stable dimensional results across batches. The coating reduces adhesive wear and improves heat resistance, which means fewer interruptions for insert changes and a lower frequency of unplanned machine stops. Such material and surface treatment choices generate reliable tool life and steady performance even when sharp edge integrity is essential for the process.

Precision geometry that eases tool selection and fitment

The insert follows the ISO DNMG format with a 55° rhomboid profile and a corner radius 1.2 mm, combining profile control with edge strength. A 4.76 mm thickness and rhomboid shape provide a predictable engagement with matching holders, while the cylindrical hole ensures secure fastening with compatible clamps and screws. Compatibility to a holder is determined by form, clearance angle, tolerance class, fastening method, size and thickness; these parameters should be checked against the intended external holder or boring bar to ensure correct seating and repeatability. Correct match-up reduces vibration and supports consistent surface quality.

Productivity gains from controlled chip flow and indexing

Equipped with a double-sided chipbreaker, the insert affords two usable orientations that help extend the in-process life before indexing is required. The chipbreaker geometry promotes stable chip formation and evacuation, lowering the risk of entanglement and toolmarking on the workpiece. Together with the sharp cutting edge quality of the AH120 grade, this results in shorter cycle times and improved first-time-right ratios for turning tasks. As part of a complete system—indexable insert, appropriate external holder or boring bar, and the correct shim/clamp and replacement screws—this insert supports efficient changeovers and reproducible machining.

Practical notes on application and handling

Designed specifically for turning, the indexable component is suitable where a balance between sharpness and process security is required. The insert is manufactured to ISO tolerances that aid quick substitution and consistent clamping. When replacing or fitting, verify holder geometry and fastening specification; using the correct clamp set and replacement screws maintains seating stability and repeatability. The physical dimensions and hole style simplify inventory management for workshops standardising on ISO-form inserts.

FAQ

What materials is this insert intended for?
The AH120 grade insert is designed for turning applications where a sharp cutting edge and process security are required; the DNMG110412 AH120 insert performs well across typical turning tasks that demand wear and chipping resistance.

How many usable edges does the insert provide?
The DNMG110412 AH120 indexable insert features a double-sided chipbreaker, offering multiple usable orientations before indexing or replacement is required.

What dimensions are critical when matching a holder?
Key dimensions are the 55° geometry, 4.76 mm thickness, 11 mm size and the free angle; these determine fit and seating with the chosen external holder or boring bar when using the DNMG110412 AH120.

Does the insert require a special fastening arrangement?
The insert uses a cylindrical hole for secure fastening; compatibility depends on the holder’s clamp or screw system and adherence to the ISO tolerance class for the DNMG110412 format.

How does the PVD coating benefit machining with this insert?
The PVD coating on the AH120 grade reduces adhesive wear and increases thermal resistance, which supports longer tool life and more consistent cutting-edge performance during turning cycles.
