TNMG 160408 AH8005 turning insert — Tungaloy, 60° triangular PVD carbide

The TNMG160408 AH8005 is an ISO triangular turning insert engineered for stable external and internal turning of heat-resistant alloys and other demanding materials, offering a robust grade and precise geometry for repeatable results.

• ISO triangular 60° geometry
• PVD-coated carbide grade AH8005
• 0.8 mm corner radius for durability
• Double-sided chipbreaker, cylindrical hole

Reliable wear resistance for heat-resistant alloys

The combination of a PVD-coated surface and a wear-resistant carbide substrate in grade AH8005 gives the insert excellent performance at elevated temperatures and in demanding cuts. The coating reduces flank wear and adhesion when machining high-temperature alloys, while the substrate maintains edge strength; this synergy extends cutting life and supports consistent cycle times. As a result, throughput remains stable even under repetitive production conditions.

ISO format and straightforward holder compatibility

Built to the ISO specification, the insert’s geometry and dimensions simplify selection of a matching external holder or boring bar. Compatibility is determined by form, relief angle, tolerance class, clamping method, size and thickness — here ISO TNMG 160408 with a 4.76 mm thickness and a cylindrical hole for positive clamping. The 60° triangle and standard dimensions permit rapid integration into existing tool systems, reducing setup time and ensuring predictable tool behaviour across comparable machines.

Design choices that cut downtime and improve surface finish

A double-sided chipbreaker and triangular shape allow multiple usable edges before replacement, lowering tool change frequency and helping maintain consistent surface quality. The 0.8 mm corner radius supports both light finishing and moderately heavy cuts, balancing strength and edge definition to avoid chatter on stable setups. The overall plate thickness contributes to rigidity; combined with an appropriate chipbreaker and the right insert grade, this results in reliable chip control and fewer interruptions on the shopfloor.

FAQ

Is this insert compatible with standard TNMG holders?
The TNMG160408 AH8005 Tungaloy turning insert follows ISO sizing, so compatibility depends on matching the holder’s form, relief angle, tolerance class, clamping method and plate dimensions rather than on the insert alone.

Which workpiece materials suit the AH8005 grade?
The AH8005 grade on this insert is formulated for wear resistance in heat-resistant alloys and other hard materials; it performs well when a stable set-up and appropriate cutting data are used.

What benefits does the PVD coating provide?
The PVD-coated surface reduces adhesion and abrasion at elevated temperatures, improving flank wear resistance and allowing longer effective cutting life for the TNMG160408 insert when machining demanding alloys.

How does the double-sided chipbreaker affect productivity?
A double-sided chipbreaker supplies multiple usable edges and predictable chip formation, which lowers tool change frequency and helps keep cycle times consistent in production.

Can the 0.8 mm corner radius be used for finishing passes?
Yes, the 0.8 mm radius offers a compromise between edge strength and finish capability; it is suitable for light finishing and semi-finishing cuts on rigid setups.
