TNMG160408 AH6235 — ISO turning insert, PVD-coated carbide, 60° by Tungaloy

TNMG160408 AH6235 is an ISO-format turning insert designed for general external and internal turning tasks, especially suited to stainless steel and interrupted-cut applications.

PVD-coated AH6235 for stainless steel Double-sided chipbreaker for versatile use 60° triangular insert with 0.8 mm radius Compatible with ISO 160408 holders

Consistent performance for demanding turning operations

The combination of a PVD-coated surface and the AH6235 carbide grade provides a balance between wear resistance and toughness, which is particularly valuable when machining stainless steel or when interruptions in the cut occur. The coated layer reduces built-up edge and improves adhesion resistance at elevated temperatures, while the substrate grade maintains edge stability under mechanical shock. This geometry supports reliable material removal rates and helps to reduce unplanned rework, which directly contributes to a more efficient production flow.

Geometry and chip control that reduce downtime

The 60° included angle and 0.8 mm radius give the insert mechanical strength at the cutting edge, improving resistance to chipping. The double-sided chipbreaker design enables consistent chip formation and evacuation on both cutting edges, extending usable edge life before rotation or replacement is required. Together, these features lower tool change frequency and contribute to predictable cycle times—an economic advantage for batch production and mixed-series turning alike.

System compatibility and practical assembly details

Compatibility is determined by insert form, relief angle, tolerance class, fixation and thickness; this ISO-format insert has a 0° relief angle, a thickness of 4.76 mm and is supplied with a cylindrical hole for secure clamping. The triangular plate format provides three usable cutting edges per side, optimising cost-per-edge. When paired with a correctly matched external holder, clamping set and replacement screws, the system offers repeatable positioning and stable machining, supporting fine surface finishes and dimensional accuracy in turning operations.

FAQ

What materials is this insert designed for? The TNMG160408 AH6235 insert is formulated for machining stainless steel and other materials where a tougher grade and good chip control are required.

Can the insert handle interrupted cuts? Yes, the AH6235 grade and the insert geometry make the TNMG160408 AH6235 well suited to interrupted cutting conditions and applications with increased risk of chipping.

How many usable edges does the insert provide? The triangular plate form offers three edges per side; with double-sided use this increases the number of indexable edges available before disposal.

What clamping style is required for this insert? A holder compatible with ISO 160408 geometry and a clamping system that accepts a cylindrical-holed triangular insert are required for secure fixation and repeatable positioning.

Does the coating improve tool life at higher cutting speeds? The PVD coating on the AH6235 grade enhances adhesion and thermal resistance, helping to maintain tool life and surface quality at elevated cutting speeds.
