DNMG 110404 AH6225 indexable turning insert – rhombic, 55° for turning by Tungaloy

DNMG 110404 AH6225 Tungaloy turning insert delivers a universal solution for medium turning of stainless steels, combining a sharp, resilient cutting edge with ISO‑standard compatibility for straightforward holder selection

• ISO‑standard rhombic insert, 55° orientation
• PVD‑coated AH6225 grade for stainless steel
• Double-sided chipbreaker for flexibility
• Cylindrical‑hole clamping, 4.76 mm plate thickness

Consistent surface finish from a grade made for stainless steels

The PVD‑coated carbide grade AH6225 is formulated for the demands of stainless steel machining, balancing a sharp cutting edge with edge stability under variable conditions. This composition reduces built‑up edge and improves consistency in surface finish when performing external or internal turning. For applications that require predictable dimensional results at moderate cutting data, the combination of coating and carbide substrate means fewer interventions, longer productive cuts and a more efficient process flow.

Predictable set‑up and replacement thanks to ISO compatibility

The rhombic insert follows the ISO‑standard DNMG110404 geometry, which defines shape, relief angle and tolerance class; this standardisation ensures compatibility with a wide range of outside holders and boring bars. The cylindrical hole enables conventional screw clamp mounting, while the 4.76 mm plate thickness and 11 mm size provide mechanical stability in interrupted cuts. These measurable specifications simplify tooling inventories and spare‑part management, enabling rapid replacement and reproducible clamping accuracy across setups.

Lower process costs through stable chip control and tool life

A double‑sided chipbreaker design allows the insert to be flipped, providing two usable edges and extending the effective life per insert. Combined with the PVD coating, the cutting edge resists abrasion and heat, which contributes to fewer tool changes and lower per‑part production costs. In medium turning operations the result is improved productivity and reduced downtime, with the economic advantage of extended service intervals without sacrificing surface quality or repeatability.

Practical selection pointers for reliable results on the lathe

Selecting the appropriate chipbreaker style and matching the insert to a compatible holder are the decisive steps for successful turning. The 55° approach angle favours stable cutting in general turning tasks and influences chip flow and cutting forces; a 0.4 mm corner radius helps achieve a balance between edge strength and surface finish. When machining stainless steels, choose cutting parameters that moderate heat build‑up and exploit the AH6225 grade’s resistance to built‑up edge for consistent part quality.

FAQ

What materials is this insert intended for?
The AH6225 PVD‑coated carbide insert is designed principally for machining stainless steels in medium turning applications, offering a balance of sharpness and edge stability.

How does the DNMG110404 geometry affect holder selection?
The ISO DNMG110404 designation ensures the rhombic shape, relief angle and size match ISO‑compatible outside holders and boring bars; the cylindrical hole accepts standard screw clamping mechanisms.

How many cutting edges are available per insert?
Thanks to the double‑sided chipbreaker, the insert provides two usable cutting edges, effectively doubling the number of edges before replacement is required.

What surface finish can be expected with a 0.4 mm radius?
A 0.4 mm corner radius tends to produce a good compromise between edge strength and surface finish, yielding consistent surfaces in general turning while maintaining robustness under moderate loads.

Is the insert suitable for interrupted cuts?
The 4.76 mm thickness and rhombic form provide sufficient rigidity for many interrupted turning tasks when paired with a robust holder and correct cutting data.
