TPMT16T308-PS AH6235 — TPMT 16T308 ISO turning insert for turning applications by Tungaloy

The TPMT16T308-PS AH6235 is an ISO-standard triangular turning insert designed for external and internal turning, optimised for stainless-steel machining and interrupted cuts.

• PVD-coated carbide grade AH6235
• Suitable for stainless-steel machining
• 0.8 mm corner radius for robustness
• ISO triangular format, 60° included angle

Secure chip control when machining stainless steel

The PVD-coated AH6235 grade offers a balance of toughness and wear resistance that is particularly beneficial for stainless-steel applications and conditions with intermittent cutting. The combination of the PS chipbreaker and a PVD coating reduces the risk of built-up edge and chipping during interruptions, which translates into fewer rejects and more predictable production runs. This insert is thus suited to turning tasks where material stickiness and thermal sensitivity demand a tougher grade rather than a hard, brittle coating.

Geometry that improves surface finish and repeatability

A 60° triangular shape with a 0.8 mm corner radius delivers a reliable compromise between edge strength and the ability to produce defined contour radii. The 11° clearance angle and ISO conformity ensure compatibility with widely used holders; the standardised geometry makes tool changes and programme validation straightforward. For operators less familiar with insert geometry: a larger corner radius increases edge support and helps maintain dimensional stability under vibration, while the triangular format supplies multiple indexable cutting edges to reduce tooling costs.

Process efficiency through longer edge life and stable cutting

Selecting the right grade and chipformer reduces downtime for insert changes. The PVD coating improves resistance to abrasive wear and adhesion, extending effective cutting life in demanding cycles and helping to maintain surface quality over longer runs. Combined with the PS chipbreaker and the insert’s mechanical design, the result is fewer tool interventions and a more consistent output—advantages that contribute directly to lower production costs and improved throughput in turning operations.

FAQ

Which materials is this insert best suited for?
The TPMT16T308-PS AH6235 is optimised for stainless-steel machining; the AH6235 grade provides toughness for interrupted cuts and applications with increased risk of chipping.

Can the insert be used for internal turning as well as external turning?
Yes, the ISO triangular format and geometry of the TPMT16T308-PS AH6235 make it suitable for both external and internal turning operations when paired with the appropriate holder.

What does the 0.8 mm corner radius mean for machining results?
A 0.8 mm corner radius increases edge strength and improves dimensional stability under load, helping to achieve consistent surface quality and longer tool life compared with very small radii.

How does the PS chipbreaker influence chip formation?
The PS chipbreaker is designed to produce manageable chips in stainless-steel turning; combined with the PVD-coated AH6235 grade, it reduces tendency to form long, tangled chips and lowers the risk of edge failure.

Which SKU should be referenced when ordering or enquiring?
Use SKU TUN6890208 or article number 6890208 when ordering the TPMT16T308-PS AH6235 insert from Metav Werkzeuge.
