DNMG 150404 AH120 — PVD‑coated carbide turning insert, 0.4 mm radius (Tungaloy)

A DNMG150404 AH120 indexable turning insert designed for ISO‑standard external and internal turning, offering a wear‑resistant PVD‑coated carbide grade for process‑secure machining.

• DNMG 150404 AH120 PVD-coated carbide for durability
• Double-sided chipbreaker for consistent chip control
• 0.4 mm corner radius for precise profile turning
• ISO rhombic plate, 55° lead angle, with cylindrical hole

Longer tool life through a hard PVD layer and robust carbide grade

The combination of PVD‑coated carbide and the AH120 grade delivers a balance of abrasion resistance and edge stability that supports sustained production runs. The thin, hard PVD layer reduces friction and improves thermal resistance at the cutting edge, which translates into extended tool life and fewer index changes. This performance is particularly valuable where the machining strategy demands a sharp cutting edge alongside reliable wear behaviour, helping to keep process interruptions to a minimum while maintaining consistent component quality.

Consistent chip control and improved component finish

Built‑in chip control comes from the double‑sided chipbreaker, which stabilises chip formation across a variety of cutting conditions. The 0.4 mm corner radius provides sufficient edge strength for finishing and profile work while allowing accurate contouring; a larger radius would increase strength but reduce form fidelity, whereas a smaller radius sharpens the profile at the expense of durability. The insert’s 55° lead angle also influences cutting forces and surface result, offering a good compromise between cutting direction and accessibility for external and internal turning operations.

ISO compatibility and secure mounting for repeatable results

Made to the ISO‑standard form, this rhombic insert features a cylindrical hole and a plate thickness of 4.76 mm, supporting secure clamping in compatible external holders or boring bars. Compatibility with a given holder depends on form, relief angle, tolerance class, fastening method, size and thickness; correct matching prevents movement under load and ensures repeatable seating when indexing. The clear, standardised geometry simplifies tool inventory and replacement, reducing set‑up time on the shop floor.

Application guidance for reliable turning performance

Intended for general turning duties, the insert performs well in external and internal operations where a sharp edge and process reliability are priorities. Selection of the chipbreaker style and the AH120 grade should be aligned with the workpiece stability and the chosen cutting strategy to achieve the desired balance of productivity and surface quality. Properly matched tooling, combined with correct clamping and cutting parameters, results in higher uptime and more predictable tool life for production environments.

FAQ

What machining operations is this insert designed for?
The DNMG150404 AH120 indexable insert (Tungaloy, SKU 6854299-Tungaloy) is intended for external and internal turning operations and is specified where a sharp cutting edge and process reliability are required.

How does the AH120 grade affect tool life and performance?
The AH120 grade is a PVD‑coated carbide formulation that improves wear resistance and edge security under typical turning conditions, extending tool life and supporting stable production.

Why is the 0.4 mm corner radius important?
A 0.4 mm corner radius offers a compromise between edge strength and profile accuracy, enabling precise contour turning while maintaining sufficient resistance to edge chipping.

How is compatibility with toolholders ensured?
Compatibility depends on the insert’s form, relief angle (0°), tolerance class, fastening method, size and thickness; the ISO rhombic geometry and cylindrical hole facilitate standardised mounting in compatible holders.

Can the chipbreaker be used for a range of cutting conditions?
The double‑sided chipbreaker provides consistent chip control across varied cutting parameters, but chipbreaker selection should be matched to workpiece stability and machining strategy for optimal results.
