TPMT 16T308 AH6235 — ISO triangular turning insert for turning (Tungaloy)

The TPMT16T308-PM AH6235 is an ISO-indexable triangular insert engineered for external and internal turning, designed specifically for stainless steel, interrupted cuts and applications with increased breakage risk.

• PVD-coated carbide grade AH6235
• Designed for stainless steel machining
• Triangle 60° form, 0.8 mm nose radius
• Cylindrical hole with one-sided countersink

Proven performance for stainless steel and difficult cuts

The combination of a PVD-coated surface and the AH6235 carbide grade provides a tougher cutting edge optimised for stainless steel and interrupted cutting conditions. The PVD coating enhances wear resistance and reduces built-up edge, while the substrate grade is balanced for toughness rather than maximum hardness. This balance decreases the likelihood of edge chipping during interrupted cuts and prolongs effective tool life, delivering measurable improvements in process reliability and component quality for serial and job-shop turning operations.

Geometry and clamping that ensure repeatable results

The insert’s 60° triangle shape and 0.8 mm nose radius give a predictable engagement geometry for a wide range of turning passes. With a plate thickness of 3.97 mm and a 11° clearance angle, the insert matches common ISO holder dimensions; compatibility is governed by form, clearance angle, tolerance class, fastening, size and thickness. The insert features a cylindrical hole with one-sided countersink (40°–60°) for secure clamping and consistent seating in compatible holders, reducing vibration and improving surface finish stability.

Chip control and surface finish with the PM chipbreaker

The PM chipbreaker is tailored to general finishing and medium-depth cuts, promoting controlled chip formation in stainless steel and similar alloys. Controlled chips lower the risk of entanglement, permit higher feed rates in many cases and simplify automated chip handling. The engineering of the chipformer reduces cutting irregularities, which contributes directly to improved surface roughness and reduced downstream finishing time — a clear operational advantage for production lines aiming for consistent component tolerances.

System thinking: how the insert integrates into the tool setup

Delivered as an ISO-indexable cutting plate, the insert forms part of a modular system that includes a matching external holder or boring bar, a shim/clamp set and replacement screws as required. The carbide substrate and PVD finish are suited to a broad range of turning tasks when combined with the correct holder geometry and clamping torque. For ordering and inventory control, the item is listed under manufacturer article number 6890215 and manufacturer SKU TUN6890215, enabling straightforward procurement and traceability in procurement systems.

FAQ

What materials is this insert best suited for?
The insert is optimised for stainless steel and similar alloys; the AH6235 grade and PVD finish provide toughness and wear resistance suitable for interrupted cuts and challenging stainless steel applications.

How does the PM chipbreaker affect machining performance?
The PM chipbreaker promotes controlled chip formation for finishing and medium cutting depths, improving surface finish and reducing the likelihood of chip-related interruptions when using the TPMT16T308-PM AH6235 insert.

Which holder characteristics are required for proper fit?
Compatibility depends on the insert form, 11° clearance angle, tolerance class, fastening method, size and thickness — ensure the holder matches the ISO triangular 60° geometry and clamping provisions.

What information is useful when reordering this insert?
Use the manufacturer article number 6890215 or manufacturer SKU TUN6890215 to ensure the correct AH6235 PVD-coated carbide grade and PM chipbreaker variant are supplied.

Can this insert be used for both external and internal turning?
Yes, the indexable triangular design is suitable for both external and internal turning when paired with an appropriate external holder or boring bar and correct clamping components.
