DNMG150416 AH6225 Tungaloy indexable turning insert — PVD‑coated carbide for turning

The DNMG150416 AH6225 is an ISO‑standard indexable turning insert intended for external and internal turning applications, optimised for stainless steels and variable machining conditions.

• PVD‑coated carbide for stainless steels
• ISO‑compliant 55° rhombic geometry
• 1.6 mm corner radius, robust cutting edge
• Double‑sided chipbreaker with cylindrical hole

Higher productivity on stainless steels through consistent cutting behaviour

The AH6225 grade combines a PVD‑coated carbide substrate with a geometry tuned for turning of stainless steels, producing a stable cutting edge under changing conditions. The rhombic 55° form promotes predictable chip flow and access in both external and internal operations, while the double‑sided chipbreaker aids chip control in interrupted cuts. Explaining the benefit: PVD coating increases surface hardness and reduces built‑up edge formation, which leads to longer effective tool life and fewer tool changes during production. The design therefore supports improved cycle times and consistent surface finish quality.

Clear compatibility rules for holders and reduced setup risk

Compatibility depends on insert shape, clearance angle, tolerance class, fastening and thickness; the ISO designation guarantees a standardised fit for matching toolholders and boring bars. The ISO‑standard marking simplifies procurement and reduces the risk of mismatch in automated setups. The cylindrical hole and central fixing accommodate many standard clamping systems; the 0° clearance angle and rhombic profile should be checked against the chosen toolholder to ensure correct rake and lead. This clarity shortens setup time and decreases the chance of rework due to incorrect seating.

Predictable edge life and easier process planning

With a 1.6 mm corner radius, the insert provides a compromise between edge strength and form fidelity, helping to resist chipping while maintaining acceptable dimensional control. The universal grade is designed for moderate cutting speeds and variable conditions, delivering high process security and repeatable results across batches. For process planners, the combination of geometry and material means a more predictable maintenance schedule and fewer unexpected interruptions. The robust edge and coating together contribute to consistent results and a favourable cost‑to‑performance ratio.

FAQ

What materials is this insert best suited for?
The DNMG150416 AH6225 insert from Tungaloy is formulated primarily for stainless steels, offering a balance of a sharp, stable cutting edge and wear resistance for moderate turning operations.

Which holder types are compatible with this ISO insert?
Compatibility is determined by insert shape, size and tolerance; the ISO‑standard DNMG150416 fits standard 55° rhombic turning holders and many internal boring bars when the cylindrical hole and clamping method match the toolholder.

How does the PVD coating affect performance?
The PVD‑coated carbide surface reduces adhesion and improves thermal resistance, which diminishes built‑up edge on stainless steels and extends effective edge life for the DNMG150416 AH6225.

Is the insert double‑sided and indexable?
Yes, the DNMG150416 is double‑sided with a central cylindrical hole and is indexable, permitting rotation to a fresh cutting edge to maximise productivity and economy.

What cutting edge strength can be expected with a 1.6 mm radius?
A 1.6 mm corner radius offers enhanced edge stability against chipping while maintaining dimensional control, suitable for operations where a compromise between strength and form accuracy is required.
