TNMG 160408 AH6225 Tungaloy turning insert — PVD-coated carbide, 60° triangle

A TNMG 160408 AH6225 indexable insert for turning, engineered for stainless-steel machining with a 60° triangular profile and a sharp, resilient cutting edge.

• PVD-coated carbide grade AH6225
• Designed for stainless-steel machining
• 60° triangular profile for versatility
• 0.8 mm nose radius, double-sided chipbreaker

Higher throughput on stainless steels through a balanced grade

The combination of a PVD-coated surface and the AH6225 carbide composition delivers a reliable balance between sharpness and edge strength for turning operations on stainless steel. This grade is developed for medium machining and variable conditions, so it supports steady cutting forces and predictable wear behaviour. The result is fewer tool changes and more productive spindle time, which directly improves process efficiency on batch and continuous runs.

Geometry tuned for stability and consistent surface finish

A 60° triangular geometry plus a 0.8 mm nose radius gives a useful mix of strength and surface finish capability. The triangular shape allows multiple indexing positions, while the moderate nose radius helps maintain a stable cutting edge during external and internal turning. Combined with the double-sided chipbreaker, the geometry promotes controlled chip formation and repeatable part quality even when cutting lengths or conditions vary. The insert’s compliance with ISO indexable insert standards ensures predictable fit and clamping in compatible holders.

Practical mounting and system considerations for reliable operation

The insert is supplied with a cylindrical hole for screw clamping and a plate thickness of 4.76 mm, enabling secure fixation and correct seat height in matching toolholders. Compatibility with a holder is determined by form, clearance angle, tolerance class, fastening method, overall size and thickness; adhering to these parameters maintains clamping integrity and repeatable runout. The standardised form factor simplifies inventory and replacement routines on the shop floor, reducing setup time and helping maintain steady production cycles.

Selectivity of chipbreaker and grade for intended tasks

Selecting the right chipbreaker and the AH6225 grade supports stable chip control and broad material coverage in stainless-steel applications. For medium-depth turning and operations with intermittent cutting conditions, this insert offers the compromise between a sharp cutting edge and edge robustness. Where high demands on surface finish are required, the combination of geometry and coating helps achieve consistent results with fewer passes. For more aggressive material removal, pairing the insert with a stiffer holder and optimised cutting parameters will increase productivity while retaining tool life.
