TNMG 160404 AH6235 — Tungaloy indexable turning insert, PVD‑coated carbide, 0.4 mm radius

The TNMG160404 AH6235 is an ISO‑standard triangular indexable insert engineered for external and internal turning, optimised for stainless steel and interrupted cutting conditions.

• PVD‑coated carbide AH6235 for stainless steel
• ISO triangular insert, 16 mm size
• 0.4 mm corner radius for precise finishes
• Double‑sided chipbreaker with cylindrical hole

Reliable material performance for demanding stainless operations

The combination of the PVD‑coated carbide grade AH6235 and its ISO geometry delivers high process stability when machining challenging alloys. The tougher substrate of this grade reduces the risk of edge chipping during interrupted cuts, while the coating enhances wear resistance at elevated temperatures. As a result, cycle times remain consistent and tool life is extended, contributing to predictable production throughput and lower overall machining costs.

Geometry that simplifies set‑up and increases uptime

With its triangular shape, 16 mm size and an included angle of 60°, the insert fits a broad range of ISO holders; the cylindrical hole ensures secure clamping and repeatable position tolerance. The 0.4 mm corner radius balances strength and surface integrity, enabling tighter tolerances without sacrificing edge robustness. Compatibility is determined by form, clearance angle, tolerance class, fastening and thickness, so pairing the insert with the correct holder is straightforward and reduces trial adjustments.

Productivity advantages in interrupted and stainless cutting

The double‑sided chipbreaker is tuned to promote stable chip control in stainless steels and other adhesive materials, lowering the likelihood of built‑up edge and improving surface finish. The tougher AH6235 grade is specifically selected for operations with elevated breakout risk, providing a pragmatic trade‑off between toughness and wear resistance. This makes the insert a reliable choice for mixed production runs where both uninterrupted and interrupted turning occur.

Practical handling and economic benefits for the workshop

Because the insert is ISO‑standard, inventory management is simplified and tool changeover is fast, supporting lean manufacturing principles. The PVD coating reduces flank wear and preserves the cutting geometry longer, which means fewer indexings and replacements per production batch. Clear technical data and consistent shank compatibility translate into easier process documentation and reproducible results across shifts, improving first‑pass yield and operator confidence.

FAQ

What materials is this insert suited for?
The TNMG160404 AH6235 indexable insert (Tungaloy, SKU 6889589‑Tungaloy) is designed primarily for stainless steel and similar difficult‑to‑machine alloys, and performs well in interrupted cutting.

Can the insert be used for internal turning as well as external turning?
Yes; the ISO triangular geometry and the cylindrical hole fastening make the insert suitable for both external and internal turning when matched with the correct ISO holder.

How does the AH6235 grade affect tool life?
The AH6235 PVD‑coated carbide grade emphasises toughness to resist chipping in interrupted cuts, which typically leads to improved service life and fewer unscheduled indexings for the TNMG160404 insert.

What are the key dimensions to check for holder compatibility?
Check the plate size (16 mm), thickness (4.76 mm), included angle (60°) and corner radius (0.4 mm) against the holder specifications to ensure proper fit and clamping.

Is chip control adequate for long, continuous cuts?
The double‑sided chipbreaker is optimised for good chip formation in stainless steels and offers consistent control across a range of feeds; performance in continuous cuts benefits from correct parameter selection.
