SNMG 120402 AH6225 Tungaloy turning insert — ISO SNMG120402 for turning

The SNMG120402 AH6225 is an ISO‑format indexable turning insert designed for external and internal turning, offering a universal grade optimised for rostfreier Stahl in medium machining applications.

• PVD-coated cemented carbide grade AH6225
• Designed for rostfreier Stahl applications
• Square 12 mm insert with 90° included angle
• Double-sided chipbreaker, with cylindrical hole

Reliable cutting for stainless components and mixed batches

The PVD coating combined with cemented carbide provides a controlled edge geometry that resists premature wear while maintaining a keen cutting line. This combination supports stable chip formation under variable conditions, which is particularly important when machining rostfreier Stahl, where workhardening and strain-hardening can otherwise compromise surface finish. The insert’s geometry — a 90° included angle and a corner radius of 0.2 mm — allows predictable engagement with the workpiece and reduces the need for frequent tool changes, increasing uptime in batch production. By selecting a universal grade such as AH6225, process planners obtain a compromise between edge sharpness for cutting performance and robustness for interrupted cuts.

Compatibility and mounting that simplify toolset decisions

The SNMG format follows ISO specifications, so compatibility with standard indexable turning holders is determined by form, clearance angle, tolerance class, clamping method, size and thickness. The insert is square and double-sided, providing two usable edges per side and extending component life per insert. The presence of a cylindrical hole facilitates positive location and secure clamping in many standard holders, while the 4.76 mm thickness and 12 mm size meet common toolholder profiles. These measurable attributes enable planners to standardise on fewer holder types and reduce tool inventory complexity, supporting a leaner tooling strategy and more predictable procurement.

Productivity uplift and predictable tool life in everyday machining

For production-focused environments, the key metrics are cycle time, surface quality and repeatability. The AH6225 grade was developed for a balance of wear resistance and edge stability, delivering improved process security and consistent part finish across variable conditions. The double-sided chipbreaker aids controlled chip splitting, lowering the risk of long, entangling chips that slow operations or endanger surface quality. Together, the geometry and coating translate into fewer interventions, longer service intervals and more consistent throughput — benefits that are measurable in reduced non-productive time and higher overall tool utilisation.

FAQ

What materials is this insert suitable for?
The SNMG120402 AH6225 insert is formulated primarily for rostfreier Stahl; the AH6225 grade offers balanced wear resistance and edge stability for medium turning of stainless components.

How is the insert mounted and secured in the holder?
The insert uses a cylindrical hole for positive location and clamping; its ISO SNMG format ensures compatibility with standard indexable turning holders that accept 12 mm square inserts.

What are the key dimensional values to check before ordering?
Verify the insert size (12 mm), thickness (4.76 mm), corner radius (0.2 mm) and the 90° included angle to ensure fit with the chosen holder and the intended cutting strategy.

Does the PVD coating extend tool life for interrupted cuts?
The PVD-coated cemented carbide construction of the AH6225 grade enhances edge stability and wear resistance, improving performance under variable and interrupted cutting conditions.
