TNMG160408 AH905 TNMG ISO 160408 turning insert for Turning — PVD-coated carbide, 60° | Tungaloy

The TNMG160408 AH905 turning insert is an ISO-standard triangular indexable insert for external and internal turning, equipped with a 0° rake and a double-sided chipbreaker for reliable chip control.

• TNMG geometry 60° triangular insert
• PVD-coated carbide AH905 for wear resistance
• Double-sided chipbreaker, reversible insert
• 0.8 mm corner radius for versatile profiles

Stable cutting performance for continuous production

The PVD-coated carbide grade AH905 combines wear resistance with a chipbreak-friendly edge, designed to sustain a sharp cutting face under varying process conditions. This hardness and coating chemistry support process stability, reducing the frequency of insert changes and helping maintain component tolerances over long runs. For manufacturers seeking predictable tool life and fewer interruptions, the coated carbide chemistry delivers improved edge retention and resistance to micro-chipping compared with uncoated grades, contributing to more consistent cycle times and part quality.

Precise geometry that speeds set-up and reduces rework

The triangular 60° geometry and 0° rake enable flexible engagement angles for both facing and longitudinal turning operations. With a corner radius of 0.8 mm and a plate thickness of 4.76 mm, the design balances edge strength with the ability to produce fillets and profiles without excessive tool marks. The insert is double-sided and indexable, meaning each seat offers multiple usable edges before disposal; this reversible format lowers tooling costs per cutting edge and simplifies inventory management. Compatibility with ISO holders is governed by form, relief angle, tolerance class, clamping and thickness, allowing easy integration into standard turning tool systems.

System compatibility and application-focused selection

Integration is straightforward: the ISO insert forms the core of a system that includes an appropriate external holder or boring bar, a locating pad or clamping kit, and replacement screws as required. The plate’s cylindrical locating hole supports positive indexing and secure clamping. Selection of the correct chipbreaker and grade should match the workpiece material and machining stability to extract maximum performance from the geometry and coating. For operations that require a sharp cutting edge alongside secure, repeatable results, the AH905 choice offers a robust starting point and can be tailored through chipbreaker and holder choice to the specific production task.

FAQ

What operations is this insert designed for?
The TNMG160408 AH905 Tungaloy turning insert is intended for external and internal turning operations under ISO conventions, suitable for a wide range of general turning tasks.

Is the insert indexable and reversible?
Yes — the triangular plate with a double-sided chipbreaker is indexable and reversible, providing multiple usable cutting edges to extend tool life.

What does the AH905 grade offer in practice?
The AH905 PVD-coated carbide grade provides a balance of wear resistance and edge security, suitable where a sharp cutting edge and consistent process stability are required.

How is holder compatibility determined?
Compatibility with holders is dictated by form, relief (clearance) angle, tolerance class, clamping method, size and thickness, so the insert integrates with standard ISO turning holders when these parameters match.

Which key dimensions should be checked before ordering?
Check the ISO designation 160408, insert size 16 mm, thickness 4.76 mm, corner radius 0.8 mm and the 60° included angle to ensure fit with existing tool holders.
