DNMG 150404 AH6225 ISO rhombic turning insert, 55° geometry — Tungaloy

A DNMG150404 AH6225 indexable insert engineered for external and internal turning, optimised for machining stainless steel with a PVD-coated cemented carbide grade that balances sharpness and edge stability

• PVD-coated carbide grade AH6225
• 55° rhombic geometry, 0° clearance
• 0.4 mm corner radius for versatile finishes
• Cylindrical hole, double-sided indexable insert

Predictable cutting performance for stainless steel applications

The combination of a PVD-coated carbide grade and a 55° rhombic geometry ensures stable chip formation and consistent results when machining stainless steel. The AH6225 grade is formulated to offer a sharp yet durable cutting edge under medium cutting conditions and varying setups, supporting reliable cycle times and fewer interruptions. The 0° clearance and the insert’s geometry permit neutral cutting forces, which helps to reduce chatter on slender workpieces and enhances dimensional control during both external and internal turning.

Consistent surface quality with controlled edge strength

A corner radius of 0.4 mm provides a well‑balanced compromise between edge strength and surface finish: it resists edge chipping while enabling good part appearance without excessive cutting forces. The insert’s double-sided design and cylindrical hole allow secure clamping and economical indexing, doubling the usable cutting edges per insert and reducing tooling costs per component. The 4.76 mm plate thickness contributes to rigidity in the cutting zone, which supports stable machining and repeatable tolerances on serial production runs.

Easy integration into ISO turning systems and shop workflows

Compatibility with cartridge and screw-in holders depends on form, clearance angle, tolerance class, attachment style, size and thickness; this indexable insert fits standard ISO turning systems and is accompanied in practice by a holder, clamping kit and spare screws for quick assembly. Selecting the appropriate chipbreaker and grade relative to material, cut type and machine stability will optimise productivity and tool life. This approach reduces setup time, lowers scrap risk and provides predictable tool-change intervals—helpful for planning in process-oriented manufacturing environments.
