TNMG 160404 AH8005 — TNMG160404 turning insert by Tungaloy for Drehen

The TNMG160404 AH8005 is an ISO-standard turning insert designed for external and internal turning, offering a 60° triangular form and a wear-resistant PVD-coated carbide grade.

• TNMG geometry with 60° triangle
• PVD-coated carbide grade AH8005
• Double-sided chipbreaker, reversible insert
• Compatible with ISO turning holders

High-performance grade for demanding materials

The PVD-coated carbide of this grade delivers pronounced wear resistance in elevated-temperature environments, making it particularly effective on heat-resistant alloys and other hard materials. The surface treatment increases edge life and reduces flank wear during prolonged cuts, which translates into fewer insert changes and improved machine uptime. With its engineered cutting face, the insert supports stable machining in setups that prioritise repeatable dimensional accuracy.

Precise geometry and verified ISO compatibility

Built to the ISO-standard TNMG form, the 60° triangular profile offers predictable engagement and rigidity. The insert features a corner radius 0.4 mm, a cylindrical hole for secure fastening and a relief angle of 0°, all of which influence seat and clamping compatibility with holders. Compatibility is defined by the insert form, relief angle, tolerance class, fastening method, size and thickness; these parameters ensure correct seating in standard turning holders and tool systems, enabling consistent cutting performance across machines and applications.

Reliable chip control and extended tool life

The double-sided chipbreaker optimises chip formation and evacuation, reducing the risk of built-up edge and improving surface finish in both external and internal turning. As a reversible insert, it allows two cutting edges per side, doubling potential edge life before disposal. The combined effect of chip control and the robust carbide substrate supports higher metal removal rates where the machine setup and workpiece stability permit, improving productivity without compromising finish.

Practical application and selection guidance

Intended for turning operations, this indexable insert is suited to both finishing and more challenging machining when paired with the correct chipbreaker and cutting data. For unstable setups or particularly tough materials, select a chipbreaker and cutting parameters prioritising reduced cutting forces. For stable, rigid arrangements the insert’s grade and geometry facilitate efficient material removal while maintaining dimensional repeatability, making it a versatile choice for general workshop and production environments.

FAQ

Is this insert suitable for turning heat-resistant alloys?
Yes. The TNMG160404 AH8005 uses a PVD-coated carbide that is specified for wear resistance on heat-resistant alloys and other hard materials, offering stable performance in appropriately rigid setups.

How is compatibility with tool holders ensured?
Compatibility depends on form, relief angle, tolerance class, fastening, size and thickness; the TNMG160404 geometry and its cylindrical hole are designed to fit ISO-standard turning holders when those parameters match.

What advantages does the AH8005 grade provide?
The AH8005 grade is PVD-coated to enhance edge life and resist thermal wear, which reduces tool-change frequency and supports consistent component quality during longer production runs.

Is the insert reversible and how does that affect cost-efficiency?
Yes, the insert is double-sided and reversible; this provides multiple usable edges per insert, effectively extending service life and improving cost-efficiency when compared with single-edged solutions.

Which machining tasks are most appropriate for this insert?
Best suited to external and internal turning where a balanced combination of wear resistance and chip control is required; choose the chipbreaker and cutting data according to workpiece material and machine stability.
