TNMG220408 AH6225 Tungaloy indexable turning insert — PVD-coated carbide, 60° triangle

A TNMG220408 AH6225 Tungaloy triangular indexable insert designed for external and internal turning, optimised for medium-duty machining of rostfreier Stahl with a stable, sharp cutting edge.

• PVD-coated carbide AH6225 for rostfreier Stahl
• 60° triangular geometry, 0.8 mm corner radius
• Double-sided chipbreaker for versatile cuts
• Central cylindrical hole for secure clamping

Predictable edge life for continuous production

The combination of PVD-coated carbide and the AH6225 grade delivers a balance of wear resistance and edge stability that supports consistent tool life in variable conditions. The physical vapour deposition layer reduces flank wear and heat transfer during interrupted cuts, which translates into fewer tool changes and steadier cycle times. For production environments that prioritise repeatability, this specification helps to maintain component tolerances over longer runs while reducing the frequency of insert indexing.

Versatile geometry for a range of turning tasks

The 60° triangular geometry with a 0.8 mm corner radius and a double-sided chipbreaker provides a flexible compromise between edge strength and profile accuracy. The geometry is suitable for general external turning and light internal operations where a balance of surface finish and tool robustness is required. The chipbreaker design aids in controlling swarf formation on medium feeds and depths, lowering the risk of re-cutting and easing chip evacuation in shorter overhangs; this supports process security and predictable part quality.

ISO compatibility and secure clamping for system reliability

As an ISO-standard insert, compatibility with toolholders is defined by form, clearance angle, tolerance class, fixing method, size and thickness. The insert is furnished with a cylindrical hole, enabling secure mechanical clamping and simple replacement in existing holders. With a nominal size of 22 mm and a thickness of 4.76 mm, the insert integrates into standard tooling systems without modification. Clear specification of mounting and geometry reduces setup time and supports rapid return to productive machining after index changes.

FAQ

What materials is this insert suitable for? The TNMG220408 AH6225 insert is engineered as a universal grade particularly suited to machining rostfreier Stahl and is intended for medium-duty turning operations.

How does the PVD coating benefit performance? A PVD-coated carbide surface on the AH6225 grade reduces flank wear and improves heat resistance, extending edge life under variable cutting conditions for the Tungaloy turning insert.

Can this insert be used for internal turning? Yes, the triangular form and double-sided chipbreaker make the insert suitable for both external and light internal turning when mounted in an appropriate holder.

What determines compatibility with holders? Compatibility depends on insert form, relief angle, tolerance class, fixing method, size and thickness; the ISO designation TNMG220408 ensures standardised matching to holders that accept 22 mm triangular inserts.

Is the insert reversible or single-use? The TNMG220408 is double-sided and indexable, allowing multiple uses by indexing to fresh cutting edges until the tool reaches its wear limits.
