TNMG 160408 AH6235 — Tungaloy turning insert, PVD-coated carbide, 0.8 mm radius

A TNMG 160408 AH6235 ISO insert designed for external and internal turning, optimised for stainless steels and applications with elevated risk of chipping

• ISO triangular insert for turning applications
• PVD-coated carbide grade AH6235 for stainless steel
• 0.8 mm corner radius for precise profile control
• Double-sided chipbreaker and central cylindrical hole

Reliable cutting performance for stainless steels and interrupted cuts

The combination of a PVD-coated surface and a tougher carbide grade AH6235 provides improved resistance to built-up edge and fracture during demanding operations. The 0.8 mm corner radius supports defined profile control while the 60° included angle yields stable contact conditions on both external and internal turns. This geometry, combined with the insert’s enhanced fracture resistance, reduces downtime caused by unexpected breakouts and contributes to steadier cycle times on stainless and other work-hardened materials.

System compatibility and straightforward clamping

As an ISO-series indexable insert, compatibility with holders depends on form, clearance angle (0°), tolerance class, fastening method and plate thickness. The triangular plate form and the central cylindrical hole allow precise locating and repeatable clamping in standard TNMG holders and boring bars. The double-sided chipbreaker design makes the insert economical: once one edge is worn, a simple index restores a fresh cutting edge, reducing inventory variety and changeover time for production runs.

Practical shop-floor advantages and application guidance

The TNMG160408 AH6235 insert is aimed at turning tasks where reliable chip control and edge security matter, such as interrupted cuts and components made of stainless steels. The carbide substrate and PVD finish combine to extend edge life and maintain surface quality, lowering scrap risk and improving throughput. For integration into a tooling system, select a holder that matches the insert’s form and thickness (4.76 mm) and verify the seating and screw type for secure fixation; properly matched components ensure consistent cutting forces and repeatable part quality.

FAQ

Is this insert suitable for stainless steel turning?
Yes. The AH6235 PVD-coated carbide grade is formulated for better toughness and is suitable for turning stainless steels and operations with interrupted cuts.

How is the insert clamped in the holder?
The TNMG 160408 features a central cylindrical hole for positive locating; clamping depends on matching the holder to the ISO form, thickness and fastening type.

Can the insert be indexed to use both sides?
Yes. The insert is double-sided; edges can be indexed to present a fresh cutting edge, which improves economy and reduces tool changes.

What does the 0° clearance angle mean in practice?
A 0° clearance indicates the nominal relief at the contact surface; selection of the holder and cutting parameters should account for this to ensure stable engagement and avoid rubbing.

Is this insert suitable for interrupted cuts?
Yes. The tougher AH6235 grade and the insert geometry are intended to reduce the risk of chipping in interrupted cutting conditions.
