TNMG 160404 AH8005 — Tungaloy turning insert, PVD-coated carbide, 60°

The TNMG160404 AH8005 is a 60° triangular indexable insert designed for external and internal turning in stable machining setups

• PVD-coated carbide AH8005
• 60° triangular geometry
• 0.4 mm corner radius
• Double-sided chipbreaker with cylindrical hole

Higher uptime through wear-resistant grade and stable cutting

The AH8005 grade is a PVD-coated carbide developed for extended life when machining heat-resistant alloys and harder materials. The coating improves wear resistance and reduces built-up edge, which means fewer interruptions for insert changes and steadier component tolerances. In practice, that translates into more consistent cycle times and lower tooling consumption per part when the machining setup is rigid and properly supported.

Reliable fit and repeatable geometry for precise turning

Produced to ISO dimensions, the insert’s 60° triangular form with a 0.4 mm corner radius and 4.76 mm thickness guarantees predictable seating in standard indexable holders. The cylindrical hole and defined tolerance make the interface with the clamping system straightforward, minimising micro‑vibration and enabling improved surface finish. Attention to holder selection — matching form, clearance angle, tolerance class, fastening and size — ensures the intended cutting geometry is transmitted reliably from tool to workpiece.

Efficient chip control and practical system integration

Equipped with a double-sided chipbreaker, the indexable cutting piece provides two usable edges per side for economical use and fast indexing. The recommended system comprises the insert, a suitable external holder or boring bar, a shim/clamp set and spare screws to maintain process uptime. For mixed production runs, selecting the correct chipbreaker and grade based on workpiece material and machining stability helps achieve the required balance between productivity and surface integrity.

FAQ

Which materials are suitable for this insert?
The TNMG160404 AH8005 insert from Tungaloy is optimised for heat‑resistant alloys and harder materials; the AH8005 grade provides enhanced wear resistance for these applications.

How does the AH8005 coating affect tool life?
The PVD coating on the AH8005 grade reduces flank wear and built‑up edge, so the Tungaloy turning insert maintains cutting performance for longer periods under stable cutting conditions.

What holder considerations ensure correct seating?
Ensure the chosen holder matches the ISO form, clearance angle, tolerance class, fastening and size of the insert; correct matching prevents instability and preserves the insert’s intended cutting geometry.

How many effective cutting edges are available per insert?
Due to the double‑sided chipbreaker design and triangular form, multiple indexings are possible, providing economical edge utilisation for batch production.

Is the insert suitable for internal turning and boring operations?
Yes, the ISO‑dimensioned insert is designed for both external and internal turning when used with the appropriate boring bar or internal holder
