DNMG110408 AH6225 ISO turning insert for rostfreier Stahl by Tungaloy — 55° rhombic, PVD-coated carbide

The DNMG110408 AH6225 is a rhombic ISO turning insert designed for external and internal turning operations, offering a balanced cutting edge for medium machining tasks in rostfreier Stahl.

• PVD-coated AH6225 carbide grade
• Designed for rostfreier Stahl machining
• 55° rhombic geometry, 0.8 mm corner radius
• Double-sided chipbreaker, cylindrical hole

High-performance grade for consistent rostfreier Stahl machining

The combination of a PVD-coated surface and the AH6225 carbide formulation delivers a sharp yet stable cutting edge that tolerates variable cutting conditions. This grade is engineered specifically for rostfreier Stahl, where workhardening and built-up edge can impair productivity. The coating reduces friction and improves wear resistance, while the substrate maintains toughness; together these properties help to extend tool life and maintain component quality during medium turning cycles. For production environments that demand repeatable results, this balance between hardness and edge stability supports sustained throughput and fewer insert changes.

Geometry and mounting that simplify setup and repeatability

A 55° rhombic shape with a corner radius of 0.8 mm and a clearance angle of 0° gives a reliable compromise between strength and insert versatility. The insert is supplied with a cylindrical hole for positive clamping and stable seating in compatible holders. The double-sided chipbreaker provides two indexable cutting edges per side, maximising tool life and reducing tooling costs. Because compatibility to the holder depends on form, clearance, tolerance class, attachment and thickness, the ISO designation and clear geometric data make it straightforward to select a matching external holder or boring bar for fast, secure fitting.

Practical system integration for efficient workshop use

As part of an ISO turning insert system, the plate works within a familiar assembly: insert, suitable external holder or boring bar, support/locking kit and replacement screws. The standardised format enables quick indexing and minimal downtime when a new cutting edge is required. The PVD-coated carbide resists thermal and abrasive wear, which supports higher material removal rates when machining rostfreier Stahl under stable cutting conditions. Clear labelling and the ISO series designation aid stock management and make it simpler to match replacements across machines and operations.

When this grade and geometry are the right choice

Choose this insert where medium turning of rostfreier Stahl requires a reliable edge and good surface finish without over-specifying to exotic grades. It is suited to shops refining process stability, where a productive cutting edge and consistent chip control are priorities. The insert’s features support a broad range of component work: external facing, contour turning and internal operations with a compatible boring bar. For those seeking an economical balance of performance and durability, the AH6225 grade offers straightforward handling and predictable wear behaviour.

FAQ

What materials is this insert suitable for?
The DNMG110408 AH6225 insert is designed primarily for rostfreier Stahl; the AH6225 grade and PVD coating improve wear resistance and edge stability when machining such materials.

How many usable edges does the insert provide?
With a double-sided chipbreaker and standard indexing, the insert offers multiple cutting edges per index; the exact count depends on how the insert is mounted and indexed in the holder.

Which holder features are required for correct compatibility?
Compatibility is determined by the insert form, clearance angle, tolerance class, attachment method, size and thickness; select an ISO-compatible external holder or boring bar with a suitable clamp and screw for secure seating.

What are the main advantages of the AH6225 grade?
AH6225 provides a balanced performance for rostfreier Stahl with a combination of a sharp cutting edge and sufficient toughness, supported by a PVD coating that reduces friction and enhances wear resistance.

Is the insert suitable for both external and internal turning?
Yes — the insert is specified for both external and internal turning operations when paired with an appropriate holder or boring bar and correct cutting parameters.
