DNMG 150408 AH6225 indexable turning insert, 55° rhombic geometry by Tungaloy

DNMG 150408 AH6225 is an ISO-standard indexable insert designed for general turning applications, engineered for reliable performance on stainless steels and adaptable to a wide range of external and internal turning tasks

• PVD-coated carbide AH6225 for stainless steels
• Double-sided chipbreaker for improved chip control
• Rhombic insert with 0.8 mm corner radius
• Cylindrical-hole design for secure mounting

Consistent surface finish and longer tool life through modern coating

The insert is made from PVD-coated carbide (AH6225), a combination that delivers a sharp yet stable cutting edge in medium-turning operations. The PVD coating increases resistance to adhesive and abrasive wear and improves heat tolerance, which translates into a more consistent surface finish when machining stainless steels. For production environments where part quality and repeatability matter, this coating helps extend the useful life of the cutting edge and reduces the frequency of indexings or replacements.

Secure chip control reduces interruptions and scrap

A double-sided chipbreaker is integrated to manage chip formation under varying cutting conditions. The optimised chip geometry promotes predictable chip flow, lowering the risk of entanglement and machine stoppages. Because the insert is indexable on both sides, the effective number of usable edges increases, improving cost efficiency per edge and reducing tooling inventories. Compatibility with the toolholder depends on form, clearance angle, tolerance class, fastening, size and thickness, so selection of a matching holder ensures the intended chip-control performance.

Repeatable clamping and straightforward handling on the shop floor

The rhombic DNMG form with a 55° included angle and a cylindrical hole provides secure locating and repeatable seating in the pocket. The insert’s 0° clearance angle delivers a neutral cutting action suitable for many turning tasks, helping to maintain stable cutting forces and predictable tool life. Standardised ISO dimensions simplify inventory management and replacement procedures, enabling faster tool changes and reduced set-up times across multiple machines.

Broad application scope with demonstrable production benefits

As a universal grade for stainless steels, the AH6225 composition is configured to offer a balance between edge sharpness and robustness for medium cutting parameters and mixed conditions. The rhombic geometry is a flexible choice for both external and internal turning where access and approach angles vary. In practical terms, users benefit from fewer tool changes, more consistent part quality and an improved cost-per-part ratio when the insert is integrated into a properly configured tooling system.
