TNMG 160408 AH8005 Tungaloy turning insert – 60° triangular PVD-coated carbide

The TNMG 160408 AH8005 Tungaloy turning insert is an ISO-formatted triangular indexable insert designed for external and internal turning of hard and heat-resistant materials.

• PVD-coated carbide AH8005 for wear resistance
• Triangular 60° format with cylindrical hole
• Double-sided chipbreaker for reliable chip control
• Compatible with ISO TNMG holder systems

Boosted tool life and consistent edge performance

The PVD-coated carbide grade AH8005 combines a wear-resistant coating with a robust substrate to extend tool life when machining demanding alloys. In practice, this means fewer insert changes and longer uninterrupted production runs. The triangular geometry, with a defined 60° cutting angle and a 0.8 mm corner radius, provides a predictable cutting edge for finishing and medium turning operations. Operators and process planners benefit from the repeatable behaviour of this insert, which contributes to stable cutting forces and consistent surface quality on workpieces made from heat-resistant alloys and other tough materials.

Productivity through controlled chip formation and system compatibility

Equipped with a double-sided chipbreaker, the insert delivers improved chip control across a range of depths of cut and feeds, reducing the risk of entanglement and protecting the workpiece surface. Being double-sided effectively doubles the available cutting edges per index, which enhances cost-efficiency. The ISO designation and standardised dimensions ensure compatibility with common TNMG holders; compatibility depends on form, clearance angle, tolerance class, fastening style, size and thickness, so the insert can be integrated into existing holder systems with minimal adaptation. The cylindrical-hole design facilitates secure clamping and simple indexing, supporting fast changeovers and stable clamping under moderate to heavy machining conditions.

Practical selection, handling and application guidance

Choosing the correct chipbreaker and grade is essential: the AH8005 grade is optimised for abrasive and heat-resistant workpiece materials, while the chipbreaker geometry should match the intended feed and depth of cut to achieve the best surface finish. The insert forms part of a system that typically includes a compatible external holder or boring bar, a backing shim or clamp set, and replacement screws. Check the holder’s specifications for seat angle and tolerance to ensure precise seating. For shops transitioning from general-purpose grades to AH8005, expect improved edge stability and extended tool life when machining alloys that generate high temperatures at the cutting zone.

FAQ

What materials is this insert suitable for?
The TNMG 160408 AH8005 Tungaloy insert is designed for hard and heat-resistant alloys and performs well where high wear resistance is required.

How does the double-sided chipbreaker affect productivity?
A double-sided chipbreaker provides reliable chip control and doubles the available cutting edges, which reduces changeover frequency and improves uptime with the TNMG160408 configuration.

Is the insert compatible with standard TNMG holders?
Compatibility with standard TNMG holders depends on holder form, clearance angle, tolerance class, fastening and thickness; the TNMG160408 format follows ISO dimensions, facilitating integration with matching holders.

What advantage does the AH8005 grade offer over uncoated alternatives?
The AH8005 PVD coating increases wear resistance and thermal stability compared with uncoated grades, resulting in longer tool life and more consistent cutting-edge performance under elevated temperatures.

Can this insert be used for both finishing and medium turning?
Yes, the triangular 60° geometry with a 0.8 mm corner radius allows use in finishing and medium turning, offering a good balance between edge strength and surface quality.
