TNMG 160408 AH6225 Tungaloy turning insert for turning

TNMG160408 AH6225 is a triangular ISO indexable turning insert designed for external and internal turning, optimised for machining stainless steels.

• ISO triangular insert TNMG160408 AH6225
• PVD-coated carbide for stainless steels
• 0° clearance angle for secure engagement
• Double-sided chipbreaker with cylindrical hole

Robust, universal grade for stainless steels

The AH6225 grade combines a PVD coating with a wear-resistant carbide substrate to offer a sharp yet stable cutting edge under varying conditions. This balance reduces built-up edge and improves process stability when machining stainless steels, so consistent component quality is achieved across mixed batches. The result is fewer interruptions for edge changes and a reliable surface finish.

Straightforward fit and system compatibility

As an ISO-standard indexable insert, compatibility with the toolholder depends on geometric parameters such as form, clearance angle, tolerance class, clamping method, size and thickness. The ISO designation and the triangular form enable easy identification and rapid replacement in a standard turning system comprising an insert, matching external holder or boring bar, shim/clamp set and mounting screw. This clarity simplifies inventory management and tool set-up.

Improved chip control and secure clamping

The insert’s double-sided chipbreaker and cylindrical hole support predictable chip formation and reliable clamping force, reducing chatter and tool deflection during interrupted cuts. The combination of a 0° clearance angle and the chipbreaker geometry yields better chip evacuation in many turning scenarios, helping to maintain tool life and reduce scrap rates. These functional advantages translate into measurable productivity improvements on the shop floor.

Practical geometry for versatile turning tasks

With a 16 mm inscribed circle, 4.76 mm thickness and 0.8 mm corner radius, this triangular insert provides multiple indexed cutting edges and adequate rigidity for medium-duty operations. The 60° included angle supports both roughing and finishing when paired with appropriate feed and depth parameters. Selecting the TNMG geometry with the AH6225 grade therefore offers a cost-effective approach to flexible turning requirements while preserving tool life.
