DNMG 150612 AH6225 Tungaloy turning insert — PVD-coated carbide, 55° geometry

DNMG150612 AH6225 Tungaloy insert for ISO-standard external and internal turning applications, designed for medium machining of stainless steel with a sharp, stable cutting edge

• PVD-coated carbide grade AH6225 for stainless steel
• ISO rhombic DNMG150612, 55° cutting geometry
• Double-sided insert with cylindrical centre hole
• 1.2 mm corner radius for medium finishing

Reliable performance in stainless steel machining

The DNMG150612 AH6225 insert is a PVD-coated carbide solution developed for turning stainless steel where a balance between edge sharpness and robustness is required. The AH6225 grade offers a consistently sharp yet stable cutting edge that maintains dimensional accuracy under varying conditions, reducing rework and scrap. The PVD-coated surface improves wear resistance and helps to control built-up edge formation during intermittent cuts. For production environments that demand repeatable surface quality, this insert delivers predictable tool life and less frequent index changes, improving process uptime.

Geometry and clamping that support accuracy and access

The rhombic DNMG shape with a 55° geometry and a 1.2 mm corner radius provides a compromise between strength and profile access, enabling reliable finishing while maintaining the capability to manoeuvre in tighter workpiece features. The double-sided design increases economy by allowing two usable edges per side, and the cylindrical hole ensures secure, concentric clamping in compatible holders. Plate thickness of 6.35 mm contributes to rigidity in the assembly, lowering vibration and improving surface finish. These geometric choices translate into fewer set-up iterations and consistent component tolerances.

Compatibility, system thinking and process benefits

Designed as an ISO-standard turning insert, the plate integrates into a system comprising a matched holder, shim, clamp set and replacement screws; compatibility depends on form, relief angle, tolerance class, fixation type, size and thickness. The double-sided chipbreaker is tuned for medium turning operations and supports continuous chip control across different cutting conditions. In practice this means shorter tool-change cycles, stable cutting forces and improved cycle-time predictability. For workshops aiming to standardise tooling for stainless steel, this insert supports scalable production with dependable repeatability.

FAQ

What materials is this insert suitable for?
The DNMG150612 AH6225 Tungaloy insert is primarily formulated for stainless steel and performs well in applications requiring a stable, sharp edge for medium turning.

Can the insert be used for internal turning as well as external turning?
Yes, the ISO-standard geometry and the rhombic DNMG shape allow the insert to be used for both external and internal turning when paired with a suitable holder.

How does the PVD coating affect performance?
The PVD coating on the AH6225 grade enhances wear resistance and reduces adhesion of material to the cutting edge, improving tool life and surface quality during medium machining.

What clamping features are required for reliable use?
Secure clamping with a compatible holder, correct shim and clamp set is essential; the cylindrical hole and standard sizing support concentric mounting and repeatable positioning.

Is this insert economical for medium-series production?
The double-sided design and the universal AH6225 grade provide good edge utilisation and process stability, which supports economical medium-series production and reduced tooling costs per part.
