TNMG160404 AH8015 turning insert (TNMG 160404) — Tungaloy, PVD-coated carbide, 0.4 mm radius

A TNMG160404 AH8015 indexable turning insert designed for external and internal turning, optimised for heat-resistant alloys with a balanced mix of wear resistance and cutting-edge stability.

• PVD-coated carbide for heat-resistant alloys
• ISO TNMG 160404 triangular insert
• 0.4 mm corner radius for accurate profiling
• Double-sided chipbreaker for consistent chips

Reliable performance when machining heat-resistant alloys

The insert delivers stable cutting performance in demanding turning tasks thanks to its PVD-coated carbide substrate and the AH8015 grade, which is tailored for heat-resistant alloy machining. The coating and substrate combination provides a compromise between wear resistance and edge stability, resulting in longer intervals between indexings and fewer unscheduled tool changes. This reduces cycle-time variation and supports predictable throughput in small-batch and serial production alike.

System compatibility for straightforward integration

Designed to the ISO TNMG 160404 standard, the geometry assures compatibility with a wide range of external holders and boring bars; compatibility depends on holder form, clearance angle, tolerance class, clamping method, size and thickness. The insert is supplied with a cylindrical hole, enabling secure clamping and straightforward replacement. Specifying ISO-standard inserts simplifies tooling inventories and minimises downtime when reordering.

Edge geometry that improves process reliability

A 0.4 mm corner radius combined with a 60° insert angle provides a controlled cutting edge that balances strength and finishing capability. The double-sided chipbreaker supports uniform chip formation and evacuation, which reduces the likelihood of built-up edge and stabilises cutting forces. For operators, this means more consistent surface quality and reduced rework, while production planners benefit from steadier tool life projections.

Practical benefits for workshop and production use

The insert’s triangular form allows for multiple indexings, improving cost-efficiency per edge. The AH8015 grade is recommended as a first choice for general machining of heat-resistant alloys, making it suitable for workshops that require a single, versatile grade for a range of components. By using an ISO-standard turning insert in PVD-coated carbide, shops achieve a balance of productivity, process security and repeatable surface finish, which supports both prototype development and series manufacturing.

FAQ

What materials is this insert best suited for?
The TNMG160404 AH8015 insert is optimised for heat-resistant alloys and offers a balanced combination of wear resistance and edge stability for general machining tasks.

How does the corner radius affect surface finish and tool life?
A 0.4 mm corner radius provides a stronger cutting edge for durability while still enabling accurate profiles and consistent surface quality when using the TNMG160404 AH8015 insert.

Is the insert compatible with my existing ISO TNMG holders?
Compatibility depends on holder form, clearance angle, tolerance class, clamping and thickness; TNMG160404 conforms to the ISO TNMG standard and is compatible with holders designed for that geometry.

Can the insert be indexed multiple times?
Yes, the triangular form and double-sided chipbreaker allow multiple indexings, improving cost-efficiency per cutting edge for series and intermittent production.

What is the benefit of the PVD coating on this grade?
The PVD coating on the AH8015 grade increases surface hardness and heat resistance, enhancing wear performance and maintaining edge integrity during higher-temperature cutting.
