SNMG 120408 AH6225 Tungaloy indexable turning insert — PVD-coated carbide, square 90° geometry for turning

SNMG120408 AH6225 Tungaloy-Wendeplatte is an ISO-format indexable insert designed for external and internal turning of stainless steels, offering a balanced edge for medium cutting conditions

• PVD-coated carbide grade AH6225
• Universal for stainless steels
• Square SNMG 90° geometry
• Double-sided chipbreaker with cylindrical hole

Consistent performance for stainless steel turning

The SNMG120408 AH6225 indexable insert is designed to deliver consistent performance when machining stainless steels. The PVD-coated carbide substrate provides a sharp yet stable cutting edge, which reduces edge breakdown and keeps surface finish consistent across interrupted cuts. The integrated chip control geometry helps evacuate chips reliably, lowering the risk of re-cutting and minimising downtime. For production environments that demand repeatable results, the combination of coating and substrate translates into improved process stability and predictable tool life.

Easy integration and standardised compatibility

Thanks to the ISO designation and square SNMG format, the insert fits common ISO-compatible tool holders and boring bars without extensive adaptation. The standardised geometry — including the 90° corner configuration and the cylindrical hole for secure fastening — simplifies tool management and stockkeeping. This harmonisation reduces setup time and makes the insert straightforward to replace during routine index changes, supporting uninterrupted machining flow and efficient inventory management.

Clear guidance on cutting behaviour and benefits

The insert’s corner radius 0.8 mm and relief angle 0° balance cutting-edge strength and surface quality: a larger radius gives enhanced edge robustness for moderate depths of cut, while the geometry still permits good surface finish where required. The double-sided design offers two usable edges per index, which extends service intervals and contributes to cost-efficiency in batch production. When selecting parameters, pair the grade with moderate feed rates and appropriate coolant strategy to exploit the alloy’s wear resistance and maintain consistent results.

Durable, economical choice for everyday turning

With a PVD coating over a wear-resistant carbide substrate, this insert is optimised for longevity under varying conditions typical of stainless steel machining. The grade’s formulation aims for stable chip formation and reliable edge life, which reduces the frequency of index changes and lowers indirect operational costs. Backed by Tungaloy’s manufacturing standards, the insert supports productive machining with fewer interruptions — an advantage for job shops and production cells seeking to improve throughput while retaining surface quality.

FAQ

What materials is this insert best suited for?
The SNMG120408 AH6225 insert is intended primarily for stainless steels; the AH6225 PVD-coated carbide provides balanced cutting behaviour for medium turning operations.

How many cutting edges are available per insert?
The square, double-sided design provides two indexed cutting edges per side, allowing multiple repositions before disposal and extending overall service intervals for the insert.

What does the corner radius mean for my parts?
A corner radius of 0.8 mm increases edge robustness and helps achieve a consistent surface finish under moderate depth-of-cut conditions when using the SNMG insert.

Is the insert compatible with standard ISO holders?
Yes. The ISO SNMG format, cylindrical hole and standardised dimensions enable compatibility with commonly used ISO turning holders and boring bars.

Which features support chip control on this grade?
The integrated double-sided chipbreaker geometry and the PVD-coated substrate promote reliable chip formation and evacuation, reducing the risk of tangling or re-cutting.
