DNMG110412 AH6225 — Turning insert (ISO, 55° rhombic) by Tungaloy

The DNMG110412 AH6225 is an ISO‑standard turning insert designed for medium cutting of stainless steels, offering a PVD‑coated carbide grade and a 55° rhombic geometry optimised for stable cutting performance.

• PVD-coated carbide grade AH6225
• ISO‑standard DNMG 110412 geometry
• Rhombic 55° shape, cylindrical hole
• 1.2 mm corner radius, double-sided chipbreaker

Consistent cutting performance and wear resistance for medium turning

The PVD‑coated carbide grade delivers a hard, wear‑resistant surface that keeps the cutting edge productive under changing conditions. The AH6225 designation denotes a universal grade tuned for stainless steels, combining a sharp, stable edge with resistance to built‑up edge and flank wear. The coating enhances adhesion and thermal stability during intermittent cuts and moderate speeds, which translates into more predictable tool life and fewer unscheduled indexings. Compatibility with the chosen holder depends on form, clearance angle, tolerance class, fastening method, size and thickness to guarantee secure clamping and repeatability.

Geometry and clamping designed for interchangeability and reliable chip control

The rhombic 55° configuration provides an efficient cutting angle for both external and internal turning while the cylindrical hole ensures positive seating in ISO‑type clamping systems. The insert is double‑sided with a 1.2 mm corner radius, giving two indexed cutting edges and a compromise between edge strength and profile definition. The integrated chipbreaker geometry supports stable chip formation in a range of feed and depth settings; this reduces vibration sensitivity and improves surface finish when paired with a suitably rigid holder and machine setup.

Practical benefits for workshop productivity and process security

As part of an ISO insert system, the element works within a simple system build: the insert, a matching external holder or boring bar, a support/locking set and replacement screws. This modularity speeds tool changes and simplifies inventory. For turning jobs where material and rigidity vary, selecting the AH6225 grade together with the appropriate chipbreaker yields fewer interruptions and a consistent surface quality, making the solution cost‑effective through reduced rework and steady productivity. The combination of geometry and coating therefore supports a reliable machining strategy across general turning tasks.

FAQ

What materials is this insert suited for?
The DNMG110412 AH6225 insert is formulated primarily for stainless steels and performs well under the medium cutting conditions typical of such materials.

Is the insert indexable on both sides?
Yes, the insert is double‑sided and offers two usable cutting edges, enabling economical indexing and reduced tooling costs.

How does the PVD coating affect performance?
The PVD coating on the AH6225 grade provides improved wear resistance and thermal stability, which helps maintain a sharp cutting edge and stable chip control during intermittent cuts.

Which holder types are compatible with this ISO insert?
Compatibility is determined by form, clearance angle, tolerance class, fastening method, size and thickness; ISO‑type external holders and boring bars designed for DNMG inserts are suitable when matching those parameters.

What is the benefit of the 1.2 mm corner radius?
A 1.2 mm corner radius offers a compromise between edge strength and achievable surface finish, improving edge robustness without excessive cutting forces.
