TNMG160404 AH6225 turning insert (ISO triangle, PVD‑coated carbide)

A PVD‑coated TNMG160404 AH6225 ISO triangular insert for external and internal turning, designed as a universal grade for machining stainless steels under medium cutting conditions.

• ISO triangular TNMG form with 60° geometry
• PVD‑coated carbide grade AH6225 for stainless steels
• Double‑sided chipbreaker with cylindrical hole
• 0.4 mm corner radius for stable edge strength

Consistent performance for stainless‑steel turning

The PVD‑coated carbide grade AH6225 delivers a combination of a sharp cutting edge and robust edge stability that suits varying production conditions. The geometry with a 60° cutting angle and a 0.4 mm corner radius helps maintain dimensional stability and surface quality during medium machining. For operations where repeatability matters, this insert reduces the need for frequent rework by offering predictable wear behaviour and improved tool life compared with uncoated grades.

Universal compatibility and efficient corner indexing

Manufactured to ISO dimensions, the triangular TNMG form ensures straightforward compatibility with standard external holders and boring bars; compatibility is defined by relief angle, tolerance class, fixing method, size and thickness. The double‑sided design with a cylindrical hole allows efficient indexing, providing cost‑effective use of each plate and minimising tool change downtime. With a plate thickness of 4.76 mm and size 16, the insert suits a wide range of clamping systems and is particularly effective where stable clamping and good chip control are required.

Practical machining guidance for reliable results

Select the chipbreaker and grade to match workpiece stability and the specific stainless‑steel alloy to avoid work hardening. For the best surface finish and tool life, favour steady feeds, moderate depths of cut and a stable setup; the PVD layer on the AH6225 grade assists in thermal resistance and consistent cutting performance. The system typically comprises the ISO insert plus a matching holder, shims/clamping set and fastening screws, enabling a reproducible assembly that supports high productivity and reduced scrap rates.

FAQ

Is this insert suitable for stainless‑steel turning?
Yes. The TNMG160404 AH6225 is formulated as a universal PVD‑coated carbide grade for stainless steels, optimised for stable edge condition and medium machining.

How does the double‑sided design affect tooling costs?
The double‑sided TNMG geometry allows multiple indexings, improving cost efficiency by providing more usable cutting edges per plate before disposal.

Which chipbreaker should be chosen for unstable set‑ups?
For less rigid set‑ups, select a chipbreaker and a more stable cutting configuration to improve chip control; the AH6225 grade supports good performance under varying conditions.

Will the insert fit standard TNMG holders?
The insert conforms to ISO TNMG dimensions; fit depends on holder form, fixing method, tolerance class, size and thickness, so verify holder compatibility before ordering.

What system components are recommended with the insert?
A compatible external holder or boring bar, appropriate shims/clamping set and replacement screws form the recommended system for reliable mounting.
