TNMG 220404 AH6225 — TNMG indexable insert for Turning by Tungaloy, PVD-coated carbide, 0.4 mm radius

TNMG220404 AH6225 is an ISO-standard triangular indexable insert engineered for external and internal turning, offering a balance of edge sharpness and robustness for variable stainless-steel machining conditions

• PVD-coated AH6225 carbide
• Universal for stainless steels and mixed conditions
• 0.4 mm corner radius for fine finishing
• ISO TNMG220404 triangular insert, 60° angle

Consistent chip control and improved surface quality

The combination of a PVD-coated surface and the AH6225 carbide matrix delivers a reliable, sharp cutting edge that maintains stability during medium cutting operations. The double-sided chipbreaker is tuned for predictable chip formation, which reduces rework and contributes to a consistent surface finish on turned components. For workshops processing stainless and similar alloys, this results in fewer interruptions for chip evacuation and a lower risk of built-up edge, supporting steady cycle times and repeatable part quality.

Designed for dependable system compatibility and secure clamping

Built to the ISO TNMG220404 standard, the insert's triangular form and 60° included angle ensure straightforward matching to appropriate external holders and boring bars. Key mechanical details — 0.4 mm corner radius, plate thickness 4.76 mm, plate size 22 mm and the cylindrical hole — define the correct seating, tolerance and fastening method required by the toolholder. Compatibility is determined by form, clearance angle, tolerance class, fastening, size and thickness; the cutting system typically comprises the indexable insert, a suitable holder or boring bar, a shim/clamp set and replacement screws, ensuring safe and repeatable mounting.

Optimised for stainless steels under variable conditions

As a universal grade for stainless steels, the AH6225 specification achieves a compromise between wear resistance and a keen cutting edge, making it suitable for medium machining and operations with changing process stability. When working with varying feed or interrupted cuts, the insert's balance between toughness and hardness helps prevent premature edge failure, enabling productive machining and predictable tool life. Selection of the correct chipbreaker and matching of the insert to a stable clamping and holder arrangement will enhance performance in everyday workshop use.
