DNMG 110402 AH6225 – Turning insert, rhombic ISO, PVD-coated carbide (Tungaloy)

DNMG 110402 AH6225 is an ISO rhombic indexable insert designed for external and internal turning, offering a sharp, stable cutting edge suited to rostfreier Stahl machining.

• ISO rhombic insert DNMG form
• PVD-coated carbide grade AH6225
• Optimised for rostfreier Stahl machining
• Double-sided insert with chipbreaker

Consistent machining performance for rostfreier Stahl

The combination of a PVD-coated surface and the AH6225 carbide formulation results in a balance between wear resistance and edge sharpness that reliably handles medium cutting operations and varying conditions. For shops processing rostfreier Stahl, this means fewer interruptions for tool changes and a steadier component quality. The coating supports thermal stability at the cutting edge, while the base carbide maintains toughness, together reducing flank wear and the risk of edge chipping under intermittent cuts.

Secure clamping and ISO compatibility for straightforward setups

Built to the ISO specification and supplied in the rhombic DNMG form, the insert matches common external holders and boring bars when the form, clearance, tolerance class, fastening, size and thickness correspond. The 0° clearance specification and the cylindrical hole design ensure a reliable mechanical seat for positive clamping systems. With a plate thickness of 4.76 mm and nominal size 11, the geometry supports stable engagement and predictable chip flow in conventional turning fixtures.

Improved edge life and controlled chip formation

The insert’s double-sided chipbreaker geometry and robust carbide substrate contribute to steady chip control and prolonged edge life. A well-formed chipbreaker reduces heat concentration and chip entanglement, which in turn lowers the likelihood of built-up edge and improves surface integrity. These advantages translate into longer intervals between indexings, fewer reworks and a measurable increase in process efficiency for batch and single-piece production alike.

Practical guidance for application and process optimisation

Use the insert for both external and internal turning operations; select the chipbreaker and grade to match workpiece stability and cutting conditions. The system approach includes the ISO insert, a matching external holder or boring bar, an underlay/clamping set and replacement screws — ensuring correct fit and repeatability. For finishing passes, consider reduced feed and speed settings to exploit the sharp cutting edge, while slightly higher feeds during roughing can take advantage of the insert’s toughness without sacrificing tool life.

FAQ

Which materials are suitable for this insert?
The DNMG 110402 AH6225 insert is optimised for rostfreier Stahl and provides reliable performance across typical stainless steel turning tasks due to its PVD-coated carbide grade.

Is the insert reversible and how many cutting edges are available?
This rhombic DNMG insert is double-sided, offering multiple usable cutting edges; indexing extends service life and reduces tooling costs for repeated turning operations.

What holders are compatible with the DNMG 110402 geometry?
Compatibility depends on matching the ISO form, size, thickness and fastening; use ISO DNMG holders or boring bars that accept the DNMG110402 specification to ensure secure clamping.

How does the AH6225 coating benefit machining?
The AH6225 PVD coating enhances thermal and wear resistance while preserving a sharp edge, which is particularly beneficial when turning rostfreier Stahl under variable cutting conditions.

Can the insert be used for finishing and roughing?
Yes — with adjusted cutting parameters. The combination of a sharp, stable edge and robust substrate allows controlled finishing passes and productive roughing when the workpiece setup is sufficiently rigid.
