TNMG160412 AH6235 Tungaloy turning insert — ISO triangular insert for turning

The TNMG160412 AH6235 Tungaloy turning insert is an ISO-standard triangular indexable insert designed for external and internal turning, optimised for stainless steels and interrupted cutting conditions.

• PVD-coated carbide grade AH6235
• Optimised for stainless steel and interrupted cuts
• TNMG triangular insert, 60° cutting angle
• Cylindrical hole for secure clamping

Reliable cutting performance for demanding stainless-steel applications

The combination of a PVD-coated surface layer and a tougher AH6235 carbide formulation provides enhanced resistance to thermal and mechanical shock, which is particularly valuable when machining stainless steels or when encountering interrupted cuts. The coating reduces built-up edge formation and improves surface finish consistency, while the tougher substrate decreases the risk of edge fracture. This results in a more predictable tool life and fewer unplanned indexings, helping to keep production flows steady and to reduce scrap rates.

Compatibility and clamping that reduce setup uncertainty

Designed within the ISO TNMG family, the insert’s triangular form and 60° cutting geometry ensure straightforward compatibility with standard external holders and boring bars when the correct holder form, relief angle and clamping system are used. The cylindrical hole and tolerance-controlled dimensions facilitate secure seating with the appropriate shim and clamping set, which contributes to repeatable positioning and stable cutting conditions. Clear system integration lowers setup time and minimises the need for trial-and-error during tool changes, supporting efficient shop-floor operations.

Productivity advantages through form and chip control

The insert’s double-sided chipbreaker design enables economical indexing and consistent chip formation under varied cutting parameters, while the 1.2 mm corner radius offers a balanced compromise between edge strength and achievable surface quality. For external and internal turning tasks, selecting the matching chipbreaker and grade to the part’s material and machining stability will improve cycle times and reduce tooling costs per component. For interrupted or unstable cuts, the tougher grade helps to avoid catastrophic edge failure, sustaining throughput and predictable maintenance intervals.

FAQ

Is the TNMG160412 AH6235 suitable for machining stainless steels?
The TNMG160412 AH6235 Tungaloy turning insert (SKU TUN6889587) is specifically formulated as a tougher grade for stainless steels and interrupted cuts, offering improved resistance to edge chipping and better control of built-up edge.

Can this insert be used for finishing passes on stainless-steel components?
The TNMG160412 AH6235 Tungaloy turning insert can be used for finishing when machine and workpiece rigidity allow; the 1.2 mm corner radius provides edge strength, but for very fine surface finishes a smaller radius or a grade optimised for finishing may be preferable.

Which clamping components are required for correct use?
Compatibility for the TNMG160412 AH6235 insert depends on holder form, relief angle, tolerance class, clamping method, size and thickness; use a compatible external holder or boring bar with the correct shim and replacement screws for secure seating.

Does the insert allow indexing to extend service life?
Yes, the triangular, double-sided design of the TNMG160412 AH6235 insert enables indexing to additional cutting edges, increasing effective tool life and reducing tooling costs per edge change.

What factors determine the best chipbreaker and grade choice for an application?
For the TNMG160412 AH6235 Tungaloy turning insert, select the chipbreaker and grade based on the workpiece material, the type of cut (continuous versus interrupted), and the machine/workholding stability to achieve optimal chip control and minimise edge damage.
