SNMG120404 AH6225 Tungaloy turning insert — ISO SNMG for turning, 12 mm, 0.4 mm radius

SNMG120404 AH6225 Tungaloy insert is an ISO-standard indexable turning insert engineered for external and internal turning tasks, optimised for medium machining of stainless steels.

• ISO SNMG 120404 geometry for standard holders
• PVD-coated carbide AH6225 for stainless steel
• Sharp yet stable cutting edge for medium cuts
• Double-sided chipbreaker, 0.4 mm corner radius

Reliable cutting performance for stainless steels

The insert delivers consistent results on stainless steels thanks to the PVD-coated carbide grade AH6225, which balances a sharp cutting edge with sufficient edge stability for variable cutting conditions. The coating improves wear resistance and helps maintain a stable cutting edge across medium turning operations, reducing the frequency of tool changes and supporting a predictable process window. In practical terms, this means fewer interruptions to production and steadier component quality when machining corrosion-resistant alloys.

ISO compatibility and system integration that simplifies tooling decisions

Designed to ISO SNMG dimensions, the insert matches commonly used insert pockets when the holder’s form, clearance angle, tolerance class, fastening and thickness align correctly. Key geometric data such as 12 mm inscribed circle, 4.76 mm thickness, 0.4 mm corner radius and a 0° clearance angle enable straightforward selection of matching external holders or boring bars. The insert’s cylindrical hole and double-sided chipbreaker facilitate secure clamping and economical use of both cutting edges, making it an efficient choice for established turning tool systems.

Process reliability and productivity benefits

When selected with a chipbreaker and grade appropriate to the workpiece and machining stability, the insert supports repeatable surface finish and dimensional control. The AH6225 grade is formulated to cope with the typical demands of medium turning in stainless steels, offering a compromise between wear resistance and edge toughness that helps avoid premature flank wear or edge chipping under interrupted cuts. The standardised form and clear dimensional data reduce setup time and simplify tool inventory management, contributing to smoother shop-floor workflows and consistent throughput.
