TNMG 160404 AH6225 Turning insert (TNMG160404) by Tungaloy — PVD‑coated carbide, 60°

TNMG160404 AH6225 is an ISO‑standard indexable turning insert designed for general turning of stainless steels and mixed turning tasks, offering a balance of sharpness and edge stability for varied production conditions.

• PVD‑coated carbide for stainless steel machining
• 60° geometry for versatile turning operations
• 0.4 mm nose radius for improved surface finish

High‑performance cutting for consistent mid‑range turning

The insert combines a PVD‑coated carbide substrate with the AH6225 grade, tailored for machining stainless steels under changing conditions. This pairing provides a stable cutting edge that resists built‑up edge and maintains dimensional accuracy over longer series, which translates into fewer index changes and steadier cycle times. The 0.4 mm nose radius contributes to a smoother surface finish while retaining sufficient edge strength for interrupted cuts or variable feed. For operations where consistent results are required across different batches, the insert’s geometry helps to reduce process variability and supports efficient tool planning.

Secure compatibility and ease of integration in production setups

Designed to the ISO turning insert standard, the triangular form and 60° approach angle mean the insert integrates with common external holders and boring bars; compatibility depends on form, clearance angle, tolerance class, fastening method, size and thickness. The centrally positioned cylindrical hole and the specified thickness of 4.76 mm ensure positive clamping and repeatable seating in compatible toolholders. Using an ISO‑matched holder keeps clamping forces predictable and minimises vibration, which directly benefits surface finish and tool life. Clear labelling and ISO designation simplify inventory management in mixed‑brand toolrooms.

Predictable chip control and operational durability

The insert’s double‑sided chipbreaker geometry supports controlled chip formation for typical turning feeds and mid‑range cutting speeds, reducing frequent interruptions and helping maintain machine uptime. The AH6225 PVD layer improves resistance to flank wear and thermal softening, offering steady performance across batch runs without excessive edge degradation. In practice, this means fewer tool changes, more consistent component quality and improved overall process economy. For manufacturers seeking a practical balance between cutting efficiency and reliability, the insert offers a robust solution that aligns with standard workshop workflows.
