TNMG160412 AH6225 Tungaloy — TNMG 160412 ISO turning insert for turning applications

A TNMG160412 AH6225 Tungaloy triangular ISO insert engineered for external and internal turning, offering a sharp yet robust cutting edge for medium machining in changing conditions.

• PVD-coated carbide grade AH6225
• Universal grade for stainless steels
• Double-sided chipbreaker design

High-performance grade for consistent stainless-steel machining

The insert uses a PVD-coated carbide substrate in grade AH6225, designed to deliver a sharp and stable cutting edge under moderate cutting conditions. This composition supports improved wear resistance and thermal stability, which translates into more consistent tool life and fewer unexpected tool changes on the shop floor. Compatibility with ISO holders is determined by the insert form, clearance angle, tolerance class, mounting and thickness, so correct matching ensures the intended machining reliability.

Geometry and handling that reduce set-up time

Featuring a 60° triangular shape with a 1.2 mm corner radius and a plate thickness of 4.76 mm, the insert provides a balance between edge strength and dimensional flexibility. The cylindrical hole and standard ISO dimensions make clamping straightforward in compliant holders, while the double-sided chipbreaker enables additional indexing options for efficient use of each insert. These geometric details reduce fixture adjustments and support predictable set-up, especially when switching between external and internal turning operations.

Productivity benefits and recommended applications

The cutting concept and chipbreaker design promote stable chip formation, which helps maintain surface quality and reduce the risk of workpiece damage. The grade is specified for stainless steels and is intended for medium turning tasks under varying conditions; selecting the appropriate chipbreaker and ensuring sufficient workpiece support will result in improved cycle times and repeatable surface finishes. The system approach—ISO insert plus matching holder, clamp set and screws—supports fast reconditioning of tool assemblies and steady production throughput.

FAQ

What materials is this insert suited for?
The AH6225 grade is formulated for stainless steels; the TNMG160412 insert is therefore recommended for turning a range of corrosion-resistant alloys under medium machining conditions.

Which geometrical details should be checked for holder compatibility?
Check the ISO form (TNMG), the 60° geometry, clearance angle of 0°, plate thickness 4.76 mm and the cylindrical hole dimensions to ensure the insert fits the chosen holder and clamping system.

Is the insert reversible or indexable?
The insert is double-sided with a chipbreaker on each usable cutting edge, offering additional indexing opportunities and economical utilisation of the insert.

For which turning operations is this insert most effective?
Designed for both external and internal turning, the insert performs best in stable set-ups and is intended for medium machining; choose the chipbreaker and cutting parameters to match workpiece stability and desired surface finish.

How does the AH6225 grade affect tool life and surface finish?
The PVD coating and grade composition support a sharp, wear-resistant edge that helps preserve surface quality and extend predictable tool life under variable cutting conditions.
