TNMG220408 AH6235 ISO turning insert for external and internal turning — Tungaloy

The TNMG220408 AH6235 is an ISO-standard triangular turning insert designed for turning applications, offering a PVD-coated carbide grade optimised for stainless steels and interrupted cuts.

• PVD-coated carbide grade AH6235
• 60° triangular form with cylindrical hole
• 0.8 mm corner radius for versatile use
• Double-sided chipbreaker for stable cutting

Consistent cutting performance for demanding stainless steel work

The PVD-coated carbide grade AH6235 is formulated to deliver reliable cutting performance when machining stainless steels and other materials prone to built-up edge or chipping. Its tougher substrate and coating combination improves resistance to flaking during interrupted cuts, so tool life is extended and part quality remains stable. By selecting this grade, process windows widen and downtime from unexpected insert failure is reduced, which supports predictable cycle times on production runs.

Geometry that simplifies set-up and enhances stability

The 60° triangle geometry with a cylindrical hole provides secure clamping and straightforward positioning in compatible external and internal holders. The 0.8 mm corner radius balances edge strength with acceptable profile definition, making the insert suitable for general turning tasks where both robustness and surface finish matter. Compatibility with a given holder depends on form, clearance angle, tolerance class, attachment method, size and thickness; matching those parameters ensures the insert performs as intended within a standard ISO turning system.

Economic machining through fewer interruptions and broad applicability

Using a double-sided insert with a well-matched chipbreaker reduces the need for frequent indexings and replacements, contributing to lower process costs over time. The insert is intended for system assembly comprising the insert, a suitable external holder or boring bar, a shim/clamping set and replacement screws, which together provide a stable cutting arrangement. For shops handling mixed batches or components with interrupted sections, the design and grade of this insert help maintain productivity and part integrity without complex parameter changes.

FAQ

Which materials are suitable for this insert?
The TNMG220408 AH6235 insert is optimised for stainless steels and performs well in applications with increased risk of chipping, such as interrupted cuts; it is also applicable to a range of tougher materials where a tougher grade is beneficial.

What does the 60° triangle imply for machining?
A 60° triangular insert provides three indexing positions per side and a compact approach geometry that suits both finishing and medium turning operations; the cylindrical hole enables secure clamping in holders designed to the ISO form.

Is the insert appropriate for both external and internal turning?
Yes, the insert is intended for external and internal turning when paired with a compatible external holder or boring bar; ensure the holder matches form, clearance angle, tolerance class, attachment and size.

How many usable cutting edges does this insert offer?
As a double-sided triangular insert, the design provides multiple usable cutting edges; this geometry typically yields six cutting edges in total, allowing economical indexings before disposal.

What determines compatibility with a workholder?
Compatibility is determined by the insert form, relief angle, tolerance class, attachment method, size and thickness; verify these parameters against the chosen holder to ensure correct seating and clamping.
