DNMG150608 AH6225 ISO turning insert, PVD-coated carbide, double-sided chipbreaker — Tungaloy

DNMG150608 AH6225 is an indexable turning insert designed for external and internal turning, providing a robust cutting edge for medium machining of stainless steels and similar materials

• ISO 150608 rhomboid format
• PVD-coated cemented carbide
• Double-sided chipbreaker
• 0.8 mm corner radius, 0° clearance

Consistent cutting performance with modern coating technology

The AH6225 grade features a PVD-coated cemented carbide substrate developed for a balance of edge sharpness and wear resistance. The coating improves thermal stability during intermittent cuts and under variable conditions, which helps maintain a consistent surface finish and extends edge life compared with uncoated grades. For shops aiming to reduce downtime and part rework, the coating plus the substrate composition deliver an efficient compromise between productivity and tool longevity, particularly on stainless steels where adhesion and built-up edge are common challenges.

Design and compatibility that simplify toolset planning

Built to the ISO 150608 specification in a rhomboid form, the plate is compatible with a wide range of ISO holders when matched for form, clearance angle, tolerance class, fastening method, size and thickness. The indexable design with a double-sided chipbreaker allows economical use of the insert by rotating to fresh edges, reducing tooling consumption per component. When specifying the holder, ensure the 6.35 mm plate thickness and 15 mm size align with the clamping system; correct pairing guarantees the intended cutting geometry and secure fixation during turning operations.

Geometry and application advantages for medium machining

The insert’s 0.8 mm corner radius and 55° approach angle deliver a compromise between edge strength and surface quality: the radius supports edge robustness on interrupted cuts, while the approach geometry helps control cutting forces and chip formation. The 0° clearance (relief angle) supports stable contact geometry for turning operations. This combination is particularly suited to medium finishing and semi-finishing passes where a consistent surface and repeatable tolerances are required. Selecting the appropriate chipbreaker and cutting parameters will further optimise chip evacuation and extend life under varying feed and speed regimes.

System approach and practical recommendations for production

This insert forms part of a complete system: the ISO DNMG150608 plate, a corresponding external holder or boring bar, a suitable shim/clamp set and replacement screws. Using correctly matched components secures the intended mechanical support and repeatability at the tool edge. For process planning, consider the AH6225 grade where variable conditions and stainless steels are frequent; its balanced performance reduces the need for frequent tool changes and supports steady production throughput.

FAQ

What materials is the DNMG150608 AH6225 insert suitable for?
The DNMG150608 AH6225 insert is formulated as a universal grade for stainless steels, offering a balanced combination of a sharp edge and stable performance for medium turning operations.

How is the insert mounted and what should be checked for compatibility?
Mounting requires a compatible ISO holder matched to the DNMG150608 form, plate thickness (6.35 mm), size (15 mm) and fastening style; the insert’s cylindrical hole supports secure clamping as part of the system.

What benefits does the PVD coating bring for machining stainless steels?
The PVD-coated surface on the AH6225 grade increases thermal resistance and reduces adhesion tendencies during turning of stainless steels, helping to maintain edge integrity and consistent part finish.

Does the insert offer multiple usable edges?
The DNMG150608 is an indexable plate with a double-sided chipbreaker, enabling rotation to fresh edges and therefore improved economy per insert compared with single-edge tools.

Which features support stability on interrupted cuts?
The 0.8 mm corner radius and robust carbide substrate contribute to edge strength, providing greater resistance to chipping during interrupted or variable turning conditions with the DNMG150608 AH6225.
