TNMG 220416 AH6225 – ISO triangular turning insert for stainless-steel turning (Tungaloy)

The TNMG220416 AH6225 is an ISO triangular, double-sided turning insert optimised for external and internal turning of stainless steels, offering a sharp yet stable cutting edge for medium machining and varying conditions

• ISO triangular insert TNMG220416 for turning
• PVD-coated carbide AH6225 for stainless steel
• Double-sided chipbreaker for stable chip control
• 1.6 mm corner radius, 60° included angle

Consistent stainless-steel performance with economical tool life

The PVD-coated AH6225 carbide grade is formulated for machining stainless steel, combining a sharp cutting edge with toughness to resist work hardening and edge chipping under variable conditions. The coating improves wear resistance and heat protection, which translates into longer edge life and more predictable tool changes. For production environments where repeatable surface quality and reduced tool interventions matter, this insert delivers measurable improvements in process stability and component finish.

Geometry and compatibility that simplify setup and replacement

The triangular ISO form with a 60° included angle and 1.6 mm corner radius balances cutting-edge strength with the ability to obtain acceptable surface finishes. The insert’s dimensions—inscribed size 22 and thickness 4.76 mm—are compatible with standard ISO holders when the holder matches form, clearance angle, tolerance class, fixation, size and thickness. The insert’s 0° clearance geometry and cylindrical locating hole ensure secure clamping and repeatable positioning, reducing setup time and minimising variability between indexings.

Chip control and production benefits for mixed machining tasks

A double-sided chipbreaker offers controlled chip formation across a range of cutting depths and feeds, which helps maintain coolant access and reduces the risk of tangling or re-cutting. Being indexable on both sides makes the insert cost-effective: once one edge is worn, the insert can be rotated to expose a fresh edge. In system terms, the insert is one part of a modular setup that includes the insert, a matching external holder or boring bar, an underlay/clamping set and replacement screws—allowing fast replacement and minimal machine downtime.

FAQ

Is this insert suitable for machining stainless steels? Yes. The TNMG220416 AH6225 Tungaloy turning insert (SKU 6903219-Tungaloy) is specifically developed for stainless-steel applications, offering a PVD-coated carbide grade that balances sharpness and stability for improved tool life.

Which holders are compatible with this insert? Compatibility requires an ISO triangular holder matching the TNMG220416 geometry in form, clearance angle, tolerance class, fixation, size and thickness; ensure the chosen holder accommodates a 22 inscribed size and 4.76 mm thickness for correct seating.

How is the chip control achieved with this insert? Chip control is provided by the double-sided chipbreaker integrated into the insert design; this feature of the TNMG220416 AH6225 promotes controlled chips across a range of feeds and depths, improving coolant access and reducing chip-related disruptions.

Can the insert be used for internal as well as external turning? Yes. The insert is suitable for both external and internal turning operations; selecting the appropriate chipbreaker and cutting parameters according to component stability and material will optimise performance with the TNMG220416 AH6225.

How many usable edges are available and what about indexing? The triangular, double-sided design provides multiple indexable cutting edges; once one edge is worn, the insert can be rotated or flipped and reclamped to present a fresh edge, maximising the productivity per insert.
