TCMT16T308 AH6235 Tungaloy indexable insert — PVD-coated carbide, 60° triangle

The TCMT16T308 AH6235 is an ISO-standard triangular indexable insert designed for external and internal turning, optimised for stainless steels and interrupted cuts.

• PVD-coated carbide grade AH6235
• Optimised for stainless steel and interrupted cuts
• 60° triangle with 0.8 mm nose radius

Consistent chip control for steady productivity

The insert’s one-sided chipbreaker and PVD-coated AH6235 carbide substrate deliver predictable chip formation under varying cutting conditions. Stable chips reduce the need for frequent machine stops and minimise tool-change frequency, which contributes to higher machine uptime and lower overall cycle costs. The combination of a 0.8 mm nose radius and the triangular geometry provides a balance between sharpness for finishing and edge strength for tougher cuts, meaning fewer rejects and more consistent parts per shift.

Tailored for demanding materials and interrupted cutting

Specifically developed for turning stainless steels and applications with increased chipping risk, this grade offers a tougher substrate and a coating that resists built-up edge and abrasive wear. The PVD coating enhances surface hardness and temperature resistance while the substrate toughness helps absorb shock during interrupted cuts. For shops processing components with alternating cuts or variable feeds, the insert reduces the likelihood of premature edge failure and supports repeatable surface quality.

Quick changeover and reliable holder compatibility

As an ISO-standard turning insert, compatibility with holders is determined by form, clearance angle, tolerance class, attachment, size and thickness; the 7° clearance angle and the triangular format simplify selection of appropriate clamping systems. The insert features a cylindrical hole with a single-sided countersink (40°–60°) for secure mounting and rapid indexability. With a nominal size of 16 mm and a plate thickness of 3.97 mm, this insert fits common external holders and boring bars, enabling efficient inventory management and fast swaps during production.

FAQ

What materials is this insert best suited for?
The TCMT16T308 AH6235 insert is formulated for stainless steels and applications prone to chipping; the AH6235 grade and PVD coating provide the toughness and wear resistance required for such materials.

How does the chipbreaker affect machining performance?
The one-sided chipbreaker on this insert promotes controlled chip formation and evacuation, improving surface finish and reducing the risk of edge breakout during interrupted cuts.

Which holders are compatible with this insert?
Compatibility follows ISO norms: holders that match the triangular TCMT16T308 form, 7° clearance angle, 16 mm size and 3.97 mm thickness are suitable; correct clamping and tolerance class ensure secure mounting.

What advantages does the PVD coating bring?
The PVD coating increases surface hardness and heat resistance, which reduces built-up edge and helps maintain edge geometry under higher temperatures, extending tool life for tougher turning operations.

Is the insert easy to index and replace during production?
Yes — the ISO designation, central hole with countersink and standard triangular form enable quick indexing and replacement, supporting short downtime during batch changes.
