DNMG 150608 AH6225 Wendeplatten - Tungaloy

Combining a PVD-coated AH6225 grade with a stable 55° rhombic form and a 0.8 mm corner radius results in a reliable insert for medium-duty turning in rostfreier Stahl; order the insert directly via Metav Werkzeuge or consult their experts for the optimal chipbreaker and holder match.

DNMG150608 AH6225 ISO turning insert — rhombic 55° by Tungaloy

A DNMG150608 AH6225 ISO-standard indexable insert for external and internal turning, optimised for rostfreier Stahl and medium cutting conditions.

• ISO rhombic 55° geometry
• PVD-coated carbide AH6225
• Designed for rostfreier Stahl
• Double-sided chipbreaker, with hole

Predictable medium-duty performance for stainless applications

The rhombic 55° geometry and the AH6225 PVD-coated carbide grade combine to deliver a balance between a sharp cutting edge and robust edge retention. This configuration is especially suited to machining rostfreier Stahl where workpiece variability and moderate cutting parameters prevail. The 0.8 mm corner radius provides a durable edge that reduces the risk of premature chipping while maintaining acceptable surface finish; the coating enhances wear resistance and contributes to more consistent tool life under fluctuating conditions.

Clear system compatibility and simple integration

Compatibility with clamping systems is determined by shape, clearance angle, tolerance class, fastening method, size and thickness — all standardised for ISO inserts. The DNMG150608 AH6225 integrates into conventional ISO external holders or boring bars when matched with the correct shim and clamping set. The insert’s cylindrical hole and standard thickness of 6.35 mm facilitate secure fastening and repeatable seating, helping to reduce setup time and ensure reproducible performance across tool changes.

Engineered chip control and stable cutting behaviour

A double-sided chipbreaker tailored for general turning supports predictable chip formation and evacuation during common turning operations. Selecting the appropriate chipbreaker in conjunction with the AH6225 grade reduces built-up edge and improves surface integrity on rostfreier Stahl. The 0° relief angle combined with the insert’s geometry helps maintain an even distribution of cutting forces, which is beneficial for dimensional stability and prolongs the life of both the insert and the clamping assembly.

Practical selection advice and system considerations

When choosing this insert, pair it with a holder whose seat and tolerance match the ISO geometry to ensure full contact and correct cutting geometry. For a complete cutting system, combine the insert with a compatible external holder or boring bar, an appropriate backing shim and spare clamping screws; this modular approach supports fast insert changes and limits downtime. The product’s ISO conformity simplifies selection and cross-referencing with existing tool inventories.

FAQ

What materials is this insert intended for? This DNMG150608 AH6225 insert is formulated primarily for rostfreier Stahl; the AH6225 grade and PVD coating give a balance of sharpness and wear resistance suitable for such materials.

Which holders are compatible with this ISO insert? Compatibility is determined by ISO geometry; the insert fits ISO-standard external holders and boring bars that accept DNMG 150608-format inserts when the holder seat, tolerance and fastening match the insert form.

How does the chipbreaker affect machining performance? The double-sided chipbreaker on this insert promotes predictable chip formation and evacuation, improving surface finish and reducing the likelihood of built-up edge on rostfreier Stahl.

Can the insert be used for internal boring as well as external turning? Yes, the ISO-format DNMG150608 AH6225 is suitable for both external and internal turning when mounted in an appropriate boring bar or holder designed for the insert size and thickness.

What are the key dimensions to check when replacing an insert? Check the corner radius (0.8 mm), plate thickness (6.35 mm), plate size (15 mm) and the 55° rhombic form to ensure the replacement matches the holder and maintains correct cutting geometry.
