TNMG160404 AH6225 ISO turning insert for Turning — Tungaloy

TNMG160404 AH6225 is an ISO-standard triangular turning insert designed for efficient external and internal turning in a wide range of stainless steels.

• ISO triangular insert TNMG format
• PVD-coated carbide grade AH6225
• 0.4 mm nose radius for medium finishing
• Double-sided chipbreaker for extended use

Consistent cutting performance under variable conditions

The TNMG-format insert delivers repeatable results thanks to the PVD-coated carbide grade AH6225, which balances a sharp cutting edge with resilience under typical shop conditions. The coating improves wear resistance and thermal stability, allowing steady performance when machining stainless steels. The insert’s ISO geometry ensures compatibility with standard turning holders; form, relief angle and thickness determine the fit, making the component straightforward to integrate into existing tool systems.

Optimised geometry for surface quality and tool life

With a 0.4 mm nose radius and a 60° lead angle, the insert is set up to produce good surface finishes while maintaining edge strength during medium cutting depths. The double-sided chipbreaker supports predictable chip formation, reducing built-up edge and contributing to longer intervals between indexings. Operators benefit from lower process variability and reliable part quality without sacrificing productivity.

Practical system integration and handling

The insert is supplied double-sided, enabling economical indexing and extended service life. Its triangular form and 4.76 mm thickness fit the ISO TNMG family of holders and boring bars; compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness. A cylindrical centre hole simplifies clamping with conventional screws and clamping sets, so the insert can be integrated into standard tool systems with minimal adjustment.

Where this insert adds value in production

Chosen for turning operations where stainless steels are common, the grade is a universal option when conditions vary between finishing and medium machining. The combination of a sharp yet stable edge and a robust PVD layer gives a favourable trade-off between surface quality and tool life, helping to reduce tool-change frequency and supporting continuous production flow.
