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

The SNMG120408 AH6225 Tungaloy is an ISO square turning insert designed for external and internal turning, optimised for medium machining of stainless steels and variable operating conditions.

• PVD-coated carbide grade AH6225
• Designed for stainless steels
• Square insert, 90° cutting angle
• Double-sided chipbreaker, consistent chips

Stable cutting performance where it matters

The combination of the AH6225 grade and a PVD finish on carbide provides a balance between a sharp cutting edge and wear resistance. That balance reduces the risk of rapid edge breakdown when machining stainless steels, especially under interrupted cuts or variable feeds. The 0.8 mm corner radius supports predictable strength at the cutting edge, which leads to longer effective tool life and fewer unexpected tool changes, contributing to improved machine uptime and consistent part quality.

ISO geometry for reliable holder compatibility

The insert follows the ISO designation and a 90° included angle in a square format, with a plate thickness of 4.76 mm and an inscribed circle size of 12 mm. The cylindrical hole and standard fixing method make it straightforward to match with compatible external holders or boring bars. Compatibility depends on form, relief angle, tolerance class, fastening, size and thickness; specifying these values at procurement ensures correct seating and clamping, reducing setup time and the risk of runout or instability during turning operations.

Controlled chips and productive machining

A double-sided chipbreaker delivers consistent chip formation and evacuation in turning applications, which helps maintain a steady cutting process and improves surface finish quality. The PVD layer reduces built‑up edge tendency and enhances thermal resilience during medium cutting conditions, supporting higher feed rates where process stability permits. For workshops prioritising repeatability and productivity, this configuration offers a practical balance of tool life and finish without the need for excessive process tuning. If application details are unclear, Metav Werkzeuge provides technical advice to match the insert to the workpiece and machine setup.

FAQ

Is this insert suitable for machining stainless steels?
Yes. The SNMG120408 AH6225 insert is formulated as a universal grade for stainless steels, offering a sharp yet stable cutting edge for medium turning operations.

How is compatibility with toolholders ensured?
Compatibility depends on the insert form, relief angle, tolerance class, fastening method, size and thickness; the SNMG120408 follows ISO dimensions to simplify matching with standard external holders and boring bars.

What advantage does the double-sided chipbreaker offer?
The double-sided chipbreaker provides consistent chip control on both indexed positions, improving stability and helping to maintain a reliable surface finish across multiple tool indexes.

What benefits does the PVD coating provide on this grade?
The PVD layer increases wear resistance, reduces built-up edge formation and improves thermal behaviour during medium machining, which supports longer tool life and steadier process results.

Can this insert be used for both external and internal turning?
Yes. The square ISO geometry and reliable clamping make the insert suitable for both external and internal turning applications when the holder and setup are matched correctly.
