TNMG 110404 AH6225 Turning insert (TNMG) by Tungaloy — PVD-coated carbide, 0° clearance

A TNMG110404 AH6225 triangular ISO turning insert designed for external and internal turning, optimised for medium finishing operations on rostfreier Stahl.

• PVD-coated carbide grade AH6225
• Universal grade for rostfreier Stahl
• 0.4 mm corner radius for versatility
• Triangular TNMG shape with cylindrical hole

Stable cutting performance for consistent throughput

The combination of a PVD-coated surface and the AH6225 carbide matrix produces a cutting edge that balances sharpness with toughness, reducing flank wear during medium turning operations. This composition is tailored for applications on rostfreier Stahl, where adhesion and built-up edge are common issues; the coating improves lubricity and thermal resistance, while the substrate maintains edge support. The result is a repeatable cutting process with fewer interruptions for edge changes, contributing directly to higher machine utilisation and predictable component quality.

Accurate fit and simple indexability for reliable setups

Conforming to ISO plate geometry, the triangular insert features a 60° included angle and a 0° clearance angle, making compatibility assessment straightforward: match form, clearance, tolerance class, clamping and thickness to the chosen holder. The insert is double-sided with a cylindrical hole, enabling multiple indexings and secure clamping; plate thickness of 4.76 mm and a plate size of 11 mm provide mechanical stability in most standard external and internal turning tools. This standardisation minimises setup time and reduces the need for bespoke tooling.

Practical recommendations for process stability and surface quality

For medium machining and variable conditions, select the double-sided chipbreaker variant and pair the insert with a holder suited to the required rigidity. The 0.4 mm corner radius supports a balance between edge strength and surface finish—use the larger radius for improved robustness under interrupted cuts or reduced rigidity, and the smaller effective edge for finer finishes. Given the universal character of the grade, adjust cutting speed and feed to account for the thermal sensitivity of rostfreier Stahl and consider coolant strategies that avoid thermal shock while assisting chip evacuation. These measures extend tool life and maintain consistent dimensional accuracy.

FAQ

What materials is this insert intended for?
The TNMG110404 AH6225 insert is a universal grade designed primarily for machining rostfreier Stahl; its PVD coating and substrate balance suit variable cutting conditions on this material.

How many usable cutting edges does the insert provide?
As a triangular, double-sided indexable insert, the TNMG110404 AH6225 offers multiple cutting edges per insert, enabling several re-indexes before replacement.

What are the key dimensions to check for holder compatibility?
Check the ISO designation TNMG110404, plate thickness (4.76 mm), plate size (11 mm), included angle (60°) and clearance angle (0°) to ensure correct fit and clamping.

Is this insert suitable for interrupted cuts or unstable setups?
The 0.4 mm corner radius and robust PVD-coated carbide make the insert more tolerant of interrupted cuts than extremely fine-radius geometries, improving edge life in less stable conditions.

Can this grade be used for finishing as well as medium machining?
Yes; AH6225 offers a compromise between sharpness and edge strength that supports medium finishing. Adjust feeds, speeds and coolant to optimise surface quality on rostfreier Stahl.
