DNMG 150412 AH6225 – ISO turning insert, PVD-coated carbide by Tungaloy

DNMG150412 AH6225 is an ISO‑standard indexable insert designed for external and internal turning, optimised for medium machining and variable conditions.

• ISO‑standard DNMG shape
• PVD‑coated AH6225 grade
• Sharp yet stable cutting edge
• Suited to stainless steel turning

High‑precision cutting where stability matters

The AH6225 PVD‑coated carbide grade delivers a balance of sharpness and edge robustness that is particularly effective in machining stainless steels. As a double‑sided indexable insert, the geometry provides two usable edges before rotation, reducing tool change frequency and supporting steady production flow. The coating improves adhesion resistance and contributes to consistent surface finish during medium cutting operations.

Predictable productivity through edge control and chip management

A well‑matched chipbreaker and stable cutting edge minimise unexpected downtime by controlling chip formation and evacuation. The PVD layer on this grade enhances wear resistance, extending tool life under changing parameters. Selecting a chipbreaker suited to material and stability enables efficient heat dispersion and reduces rework, which in turn supports a measurable improvement in throughput and processing costs for routine turning tasks.

Compatibility, dimensions and practical application notes

The insert follows ISO specifications for holder compatibility, where form, relief angle, tolerance class, fastening, size and thickness determine fit. Key dimensions include a corner radius of 1.2 mm, plate thickness 4.76 mm, plate size 15 mm and an insert angle of 55°; the insert is supplied with a cylindrical hole for secure mounting. Use a suitable external holder or boring bar and match the chipbreaker and grade to the workpiece and machining stability for optimal results.

FAQ

Which materials is this insert best suited for?
The DNMG 150412 AH6225 insert is formulated for turning stainless steels and performs well under medium machining conditions where a sharp, yet stable cutting edge is required.

Is the grade suitable for interrupted cuts or variable conditions?
Yes, the AH6225 PVD‑coated carbide grade offers a compromise between edge sharpness and robustness, making it appropriate for varying cutting conditions and light interruptions.

How should the chipbreaker be selected for optimal results?
Choose a chipbreaker that matches the workpiece material, cutting depth and machine stability; the integrated double‑sided chipbreaker on this insert supports controlled chips in typical turning operations.

What mounting features must be checked for compatibility?
Ensure the holder matches the ISO DNMG form, relief angle, tolerance class and plate thickness; the cylindrical hole and 4.76 mm thickness must align with the chosen clamping system.

Can this insert be used for internal as well as external turning?
Yes, the ISO‑standard geometry and available chipbreaker variants make the insert suitable for both external and internal turning when paired with the correct holder.
