SNMG120408 AH6225 Tungaloy turning insert — PVD-coated carbide, 0.8 mm corner radius

The SNMG120408 AH6225 is an ISO-standard turning insert for external and internal turning, engineered for reliable machining of stainless steels under varying conditions.

• PVD-coated carbide AH6225
• Universal grade for stainless steel machining
• ISO SNMG120408, square form, 90° included angle
• 0.8 mm corner radius, double-sided chipbreaker

Consistent cutting performance for stainless steels

The combination of a PVD-coated carbide substrate and the AH6225 grade delivers a sharp yet stable cutting edge, specially tailored for machining stainless steel grades. This balance reduces flank wear during medium cutting depths and when operating under changing conditions, thereby extending insert life and stabilising cycle times. The coating improves oxidation resistance at elevated temperatures, which supports reliable performance on parts where temperature spikes occur during turning.

Geometry that improves chip control and surface finish

The square SNMG form with a 90° included angle and a 0.8 mm corner radius provides predictable cutting engagement and a strong cutting corner for general turning tasks. The double-sided chipbreaker ensures repeatable chip formation and evacuation on both indexes, reducing the risk of built-up edge and improving surface quality. The term "included angle" refers to the approach angle of the insert; a 90° angle is particularly suited to general-purpose external and internal turning where robust cutting action and consistent profile control are required.

System compatibility that reduces setup time and costs

As an ISO-standard insert, the unit integrates into conventional holder systems where compatibility is determined by form, relief angle, tolerance class, clamping method, size and thickness. The cylindrical hole ensures secure clamping and straightforward indexing, while the double-sided design halves the effective cost per cutting edge compared with single-sided alternatives. This combination supports streamlined tool inventory and faster changeovers in mixed-production environments, making the solution economically attractive for batch and job-shop operations. The Tungaloy manufacturing pedigree contributes to a predictable tool life and stable chip formation across a broad range of stainless steel alloys.

FAQ

What materials is this insert suited for?
The SNMG120408 AH6225 insert is designed primarily for machining stainless steels and performs well under the medium cutting conditions described for the AH6225 grade.

How does the PVD coating benefit cutting operations?
The PVD coating on the AH6225 grade enhances oxidation resistance and wear behaviour, which supports longer tool life and consistent cutting performance for stainless steel turning.

Is this insert compatible with standard SNMG holders?
Yes; the SNMG120408 follows the ISO SNMG form and integrates with compatible external and internal turning holders, subject to matching form, relief angle and clamping method.

What advantage does the double-sided design provide?
Double-sided indexing supplies two usable cutting edges per insert face, effectively reducing tooling costs per edge and simplifying inventory management.

Which industries typically benefit from this insert?
The insert is suitable for manufacturing sectors that require reliable stainless steel turning in medium operations, including general engineering, component production and maintenance workshops.
