TNMG160408 AH6225 Tungaloy turning insert — ISO triangular insert, PVD-coated carbide, 60°

TNMG160408 AH6225 is an ISO‑standard triangular turning insert designed for external and internal turning, suited to machining rostfreier Stahl in medium cutting conditions

• TNMG 160408 form, 60° cutting angle
• PVD-coated carbide grade AH6225
• 0.8 mm corner radius for stable edge
• Double-sided chipbreaker, with cylindrical hole

Consistent performance on rostfreier Stahl and similar alloys

The indexed insert offers a balanced combination of PVD-coated substrate and a universal AH6225 grade that is engineered for rostfreier Stahl. The PVD-coated surface increases wear resistance and heat tolerance, while the underlying carbide substrate keeps edge stability during interrupted cuts. For practical terms, the coating reduces adhesion and flank wear so that the replacement interval is extended under varying conditions; this results in fewer tool changes and more predictable cycle times. The design supports a stable cutting edge, which improves surface finish and reduces scrap rates in serial turning tasks.

Reliable fit and simple mounting for faster setup

Compliance with the ISO designation means the triangular insert mates with holders that accept TNMG 160408 geometry; compatibility is determined by shape, relief angle, tolerance class, fastening method, size and thickness. The insert features a 60° cutting angle, a 0° relief angle, and a with hole configuration (cylindrical hole) for secure clamping in standard seats. The 0.8 mm corner radius balances edge strength and finish: larger radii increase robustness, smaller radii improve precision. Clear knowledge of these parameters simplifies holder selection and reduces setup time while maintaining machining stability.

Productivity gains through targeted geometry and chip control

Equipped with a double-sided chipbreaker, the insert allows two usable edges per side, improving cost-effectiveness for medium machining operations. The triangular form provides multiple indexing opportunities, and the PVD-coated carbide combination ensures repeatable performance during extended runs. For practical application: use this insert for external turning and bore finishing where a compromise between edge sharpness and durability is required. Selection of the correct chipbreaker and grade for the specific workpiece material and machine stability is essential to exploit the full productivity potential; this approach reduces downtime and supports a steady production flow.

FAQ

Which holders are compatible with the TNMG160408 AH6225 insert?
Compatibility requires holders designed for TNMG 160408 geometry; the insert fits holders that match the form, free angle, tolerance class, fastening and plate thickness.

Is the AH6225 grade suitable for rostfreier Stahl?
Yes, the AH6225 PVD‑coated carbide grade is formulated as a universal grade for rostfreier Stahl, offering a balance of sharpness and edge stability for medium cutting conditions.

How does the double-sided chipbreaker affect tool life?
A double-sided chipbreaker provides additional usable edges and improved chip control, which can extend effective tool life by enabling more indexable positions and more consistent chip formation.

What advantages does the PVD coating provide?
The PVD coating enhances wear resistance and reduces built-up edge tendency, improving heat tolerance and maintaining a sharper edge for longer periods during turning operations.

Can this insert be used for internal turning and external turning?
Yes, the TNMG160408 geometry is suitable for both external and internal turning applications when paired with the appropriate holder and process parameters.
