TNMG 160404 AH8005 indexable turning insert — 60° triangular, PVD-coated (Tungaloy)

A TNMG160404 AH8005 indexable insert engineered for stable external and internal turning of heat-resistant alloys and other hard materials.

• PVD-coated carbide grade AH8005
• Double-sided chipbreaker for stability
• 0.4 mm corner radius for versatile turning

Reliable chip control for consistent cycle times

The triangular insert’s double-sided chipbreaker and PVD-coated surface combine to improve chip formation and evacuation during turning operations. Stable chip control reduces the risk of rework and unscheduled stoppages, which supports continuous production. The coating improves resistance to abrasive and adhesive wear, while the chipbreaker geometry lowers cutting forces — resulting in steadier feeds and reproducible part quality across batch production.

Geometry designed for repeatable accuracy and clamping compatibility

With a nominal 60° insert angle and a 0.4 mm corner radius, the geometry provides a balance between strength and finish capability. The insert conforms to ISO-standard dimensions, so compatibility with holders depends on form, clearance angle, tolerance class, fastening method, size and thickness. This standardisation enables straightforward integration into existing toolsets and simplifies tool selection for both external and internal turning tasks.

Material and coating optimised for demanding materials

The substrate is a wear-resistant carbide designed for stable machining; the AH8005 grade is tailored for heat-resistant alloys and harder steels where thermal and abrasive stresses are high. The PVD-coated layer enhances edge stability at elevated temperatures, extending usable life and preserving surface integrity on the workpiece. For jobs requiring a controlled balance of tool life and surface quality, this configuration provides an economical, productivity-oriented solution.

FAQ

What materials is this insert suitable for? This TNMG160404 AH8005 indexable insert is specified for heat-resistant alloys and other hard materials; the AH8005 carbide grade and PVD coating deliver wear resistance suitable for such applications.

How does the insert’s geometry affect performance? The 60° triangular geometry combined with a 0.4 mm corner radius provides a compromise between edge strength and surface finish, supporting stable machining and reproducible part quality in turning operations.

Is the insert compatible with standard holders? Compatibility is determined by insert form, clearance angle, tolerance class, fastening method, size and thickness; the TNMG160404 follows ISO dimensions to simplify holder matching.

How many usable cutting edges does the insert offer? As a double-sided triangular insert, the TNMG160404 provides multiple indexable edges; the exact number of usable positions depends on the insert orientation and clamping system used.

What benefits does the PVD coating bring to the machining process? The PVD coating on the AH8005 grade enhances edge stability at higher cutting temperatures, improves resistance to abrasive wear and contributes to longer tool life and more consistent surface finishes.
