TNMG160408 AH6225 triangular turning insert – ISO turning insert by Tungaloy, 60° geometry, PVD-coated

The TNMG160408 AH6225 is an ISO-format indexable insert designed for external and internal turning, offering a universal grade tailored for stainless steels and changing production conditions.

• ISO-standard triangular insert 60° geometry
• PVD-coated carbide grade AH6225
• Double-sided chipbreaker for consistent chips
• 0.8 mm corner radius for balanced finish and strength

Stable cutting for medium machining of stainless steels

The PVD-coated carbide grade AH6225 delivers a combination of a sharp yet stable cutting edge and wear resistance that is well suited to medium turning operations on stainless steels. The coating reduces built-up edge and assists heat resistance during interrupted cuts, while the substrate provides toughness against chipping. As a result, the insert supports consistent cycle times and reduces the likelihood of unexpected tool changes; this contributes directly to higher productivity and predictable process planning.

Reliable ISO compatibility that simplifies tool setup

Designed to the ISO dimensions, the triangular insert guarantees predictable fit and clamping behaviour with standard holders and boring bars. The 60° geometry and 0° relief angle define the approach and cutting forces, while the cylindrical through‑hole enables secure fastening. Specified dimensions such as the 16 mm inscribed circle and 4.76 mm thickness ensure mechanical stability in common holder families. For shops moving between different machines, ISO conformity reduces setup complexity and minimises adapter inventory.

Predictable surface finish and reduced downtime

The 0.8 mm corner radius balances edge strength and surface quality: a larger radius increases corner toughness, while still producing a satisfactory finish in medium material removal. The insert’s double-sided chipbreaker provides repeatable chip control and allows indexable reuse of both sides, which extends effective tool life and lowers cost per edge. Together with the PVD coating, this construction reduces the frequency of regrinds and unscheduled stops, supporting smoother production sequences and better process economics.

Guidance on selection and application

Choose the chipbreaker and grade to match workpiece condition, feed and stability. For interrupted cuts or roughing with limited rigidity, favour a more robust holder and maintain conservative feeds; for finishing, reduce feed and use the same insert to exploit the sharp edge geometry for improved surface integrity. The insert is suitable for both external and internal turning; verify holder clearance and clamping torque for optimal performance.

FAQ

What materials is this insert designed for?
The AH6225 grade is a universal PVD-coated carbide developed primarily for stainless steels, offering good performance under varying cutting conditions.

How does the 0.8 mm corner radius affect machining?
A 0.8 mm corner radius increases edge strength and improves resistance to chipping while still delivering a satisfactory surface finish in medium cutting operations.

Is the insert compatible with standard ISO holders?
Yes; the ISO designation and dimensions enable compatibility with ISO‑standard external holders and boring bars when form, tolerance and clamping match the insert specification.

How is chip control managed with this insert?
The double-sided chipbreaker provides repeatable chip formation on both usable sides, improving evacuation and reducing the risk of built-up edge in continuous turning.
