SNMG150612 AH6225 indexable insert for turning — PVD-coated carbide, 1.2 mm radius (Tungaloy)

SNMG150612 AH6225 is an ISO-format indexable insert for general turning applications, optimised for stainless steel and medium-duty machining.

• PVD-coated carbide for durable performance
• Universal grade optimised for stainless steel
• Double-sided chipbreaker for flexible use
• 1.2 mm corner radius, square 15 mm format

Engineered for reliable cutting performance and predictable tool life

The PVD-coated carbide grade AH6225 combines a sharp yet stable cutting edge with wear-resistant surface treatment to balance edge life and form stability when machining stainless steel. The coating improves thermal stability and reduces built-up edge, which translates into more consistent component tolerances and fewer interrupted cycles. With a geometry intended for medium cutting conditions, the insert supports repeatable results across batch production and mixed runs, reducing the need for frequent index changes and supporting a smoother process flow.

ISO compatibility that simplifies integration and reduces setup time

As part of the ISO turning insert family, the plate is specified to fit holders that match on form, relief angle, tolerance class, mounting and thickness. The square 15 mm format and 6.35 mm plate thickness enable secure clamping in standard external holders and boring bars; the design also anticipates use with shims, clamping sets and replacement screws as part of a complete tooling system. The 0° relief angle and standard hole (cylindrical) ensure repeatable seating and simple inventory management when pairing inserts with certified toolholders.

Geometry tuned for stability, chip control and surface quality

A 1.2 mm corner radius and a 90° approach geometry support improved part surfaces and dimensional control on shoulder and external turning operations. The double-sided chipbreaker provides two indexed cutting edges, extending usable life per insert and offering flexibility with different feed and depth settings. The central cylindrical hole contributes to secure attachment and repeatable positioning, enhancing process stability during interrupted cuts and promoting consistent chip formation.

Practical advantages for shop-floor productivity and tooling economy

Grade AH6225 is designed as a universal option for stainless steel that lowers the number of specialised grades required in stock. The combination of PVD treatment and a balanced edge makes the insert a pragmatic choice for mixed-series production where both surface finish and tool life matter. Less frequent replacements and straightforward indexing reduce downtime, while the standardised ISO form supports quick replacement and consistent setup across machines. For operations pursuing steady throughput with minimal complexity, the insert offers an effective compromise between performance and inventory efficiency.

FAQ

What materials is this insert suitable for?
The SNMG150612 AH6225 insert is intended primarily for stainless steel and performs well in medium-duty turning where a balance of surface finish and edge life is required.

How many cutting edges are available per index?
The square design with a double-sided chipbreaker provides multiple usable edges; the insert can be indexed to present a fresh edge when required, extending overall tool life.

Which holder types are compatible with this indexable insert?
Compatibility depends on holder form, relief angle, tolerance class, mounting and thickness; the ISO format is compatible with standard external holders and boring bars designed for 15 mm square plates and 6.35 mm thickness.

Can this insert be used for interrupted cuts or grooving operations?
The central cylindrical hole and the robust edge geometry enhance stability in interrupted cuts; however, suitability for specific grooving tasks should be verified against the intended holder and cutting parameters.

Is the AH6225 grade suitable for mixed-production environments?
Yes, the AH6225 grade is a universal option optimised for stainless steel, reducing the number of specialised grades required and simplifying tooling inventories.
