DNMG 150608 AH6225 turning insert by Tungaloy — PVD‑coated carbide for stainless steels

DNMG150608 AH6225 Tungaloy turning insert offering ISO‑standard indexable geometry for external and internal turning applications, designed for stable cutting and adaptable chip control

• ISO rhombic DNMG 55° geometry
• PVD-coated carbide AH6225
• Designed for stainless steels
• Double-sided chipbreaker, cylindrical hole

Consistent cutting performance with a wear‑resistant grade

The combination of a PVD‑coated carbide substrate and the AH6225 grade delivers a balance between edge sharpness and robustness, tailored for the demands of machining stainless steels under variable conditions. The coating reduces flank wear and helps maintain a sharp cutting edge during medium cutting operations, which improves component consistency over multiple tool indexings. By choosing a coating and grade matched to the workpiece, the risk of built‑up edge is reduced and surface finish becomes more predictable, supporting higher process stability and lower scrap rates.

Geometry tuned for versatility and secure clamping

The rhombic DNMG 55° form with a 0° clearance and a 0.8 mm corner radius provides a versatile cutting profile suitable for both finishing and light roughing passes. The insert is double‑sided, enabling economical indexable use, and the cylindrical hole ensures precise seating and repeatable clamping in compatible holders. As the insert conforms to ISO dimensions, integration into existing tool systems is straightforward, but compatibility must be checked for form, relief angle, tolerance class, fastening type, size and thickness to ensure correct fit and secure operation.

System benefits: predictable results and reduced downtime

Using an ISO standard insert such as this supports modular tool planning and predictable changeover routines. The insert’s stable cutting edge and effective chip control help to reduce unplanned stoppages and allow for longer, more productive tool life per index, thereby improving overall productivity. Where repeatability is essential, selecting the right combination of holder, shim and clamping kit based on the insert’s dimensions and hole style will help to preserve cutting geometry and ensure consistent part quality across batches.

Practical recommendations for successful turning

Apply these inserts for external and internal turning where stainless steels are the primary material. The double‑sided chipbreaker offers flexibility; select the chipbreaker style and grade according to component rigidity, cutting depth and the chosen feed rate. For less rigid setups, prefer more conservative feeds and ensure stable clamping of the workpiece and toolholder. If process windows are uncertain, consult tooling specialists to match holder stability and cutting data to the AH6225 grade for optimised results.

FAQ

What materials is this insert designed for?
The DNMG150608 AH6225 Tungaloy turning insert is formulated primarily for stainless steels, offering a balance of edge sharpness and durability for medium machining tasks.

How does the AH6225 grade affect machining performance?
AH6225 is a PVD‑coated carbide grade providing enhanced wear resistance and improved chip control in varying conditions, which helps maintain surface quality and tool life during medium turning.

Is the insert compatible with existing ISO DNMG holders?
Yes; the insert follows ISO dimensions, but compatibility depends on matching form, relief angle, tolerance class, fastening type, size and thickness of the holder and clamping kit.

What are the benefits of the double‑sided design?
The double‑sided construction increases economy per insert by offering two usable cutting edges, reducing tooling costs per part when secure clamping and correct indexing are applied.

Which machining tasks suit the 55° rhombic geometry best?
The 55° rhombic geometry is versatile for both finishing and light roughing operations and is particularly useful where a compromise between access and edge strength is required.
