TNMG 220408 AH6225 – Tungaloy ISO indexable turning insert, PVD‑coated carbide, 60°

TNMG220408 AH6225 is an ISO‑standard triangular insert designed for external and internal turning, optimised for rostfreier Stahl and medium cutting conditions.

• TNMG form with 60° cutting angle
• PVD-coated carbide for rostfreier Stahl
• Double-sided chipbreaker for medium cuts
• Cylindrical hole for secure clamping

Consistent cutting performance for medium turning operations

The PVD‑coated AH6225 grade provides a balance between a sharp cutting edge and edge stability, designed specifically for machining rostfreier Stahl under varying conditions. The coating reduces adhesion and built‑up edge, which improves surface finish and extends tool life in cyclic production. As an ISO indexable insert, the geometry and tolerance are standardised so that the cutting data can be applied reliably across compatible holders; compatibility is determined by form, relief angle, tolerance class, fixing method, size and thickness.

Secure clamping and straightforward indexability reduce downtime

The triangular plate with a cylindrical hole and 60° geometry allows secure mounting in a wide range of external holders and boring bars. Being double‑sided, the insert offers economical indexing: when one edge is worn, the plate can be rotated to a fresh cutting corner, which reduces tool change frequency and supports uninterrupted production flow. The insert’s 0° relief angle and defined corner radius ensure repeatable seating and consistent cutting behaviour when used with the appropriate clamping set and screw.

Grade and chipcontrol deliver reliable results in practice

The Hartmetall substrate and AH6225 formulation are tuned for medium machining of rostfreier Stahl, delivering a stable cutting edge that stands up to moderate interruption and variable conditions. The built‑in double‑sided chipbreaker helps control chip form in many common turning operations; however, the optimum chipbreaker and cutting parameters should be selected according to workpiece material, machining type and setup stability. The insert is supplied in the ISO designation TNMG220408 and is intended to be used as part of a system comprising a compatible holder, support shim and fastening hardware.

FAQ

What applications is this insert suited to?
The TNMG220408 AH6225 insert is intended primarily for external and internal turning, with the AH6225 grade optimised for machining rostfreier Stahl under medium cutting conditions.

How does the chipbreaker affect performance?
The double‑sided chipbreaker on the TNMG220408 AH6225 promotes controlled chip formation during medium cuts; selection of the chipbreaker should match the material, operation and setup stability for best results.

Is this insert compatible with standard ISO holders?
Compatibility is determined by the insert form, relief angle, tolerance class, fixing and size; the TNMG220408 geometry conforms to ISO standards and is compatible with holders designed for TNMG inserts.

What benefits does the PVD coating deliver?
The PVD coating on the AH6225 grade reduces adhesion and built‑up edge when machining rostfreier Stahl, improving surface finish and contributing to longer, more predictable edge life.

How many cutting edges are available before indexing?
As a double‑sided triangular plate, the TNMG220408 AH6225 provides multiple usable cutting edges; the exact number depends on which corners are designated for cutting and the chosen corner radius.
