TPMT 090208 AH6235 Tungaloy turning insert — PVD‑coated carbide, 0.8 mm nose radius

TPMT 090208 AH6235 is an ISO‑standard triangular turning insert designed for external and internal turning where toughness and chip‑control are required

• PVD-coated carbide AH6235 for stainless steels
• ISO triangle insert, size 09, 0.8 mm nose radius
• Cylindrical hole with 40°–60° one-sided countersink
• 11° clearance angle and 2.38 mm plate thickness

Durable grade for demanding stainless‑steel work

The PVD‑coated AH6235 grade provides a tough, abrasion‑resistant cutting edge that is particularly suited to machining stainless steels and situations with intermittent engagement. The coating stabilises the cutting edge at elevated temperatures and lowers the risk of built‑up edge, while the substrate controls fracture under interrupted cuts. This results in more consistent tool life and fewer unplanned tool changes, improving process throughput and reducing overall machining costs.

Stable geometry for consistent surface quality

The triangular ISO geometry and a 0.8 mm nose radius deliver a balance between edge strength and form accuracy, making the insert suitable for medium‑duty finishing and semi‑finishing operations. The 11° clearance angle and 2.38 mm plate thickness ensure secure seating and resistance to edge deflection, which supports a stable cutting action and consistent surface finish. Owing to the robust shape, repeatability between indexings is improved and tolerance adherence becomes more reliable.

Plug‑and‑play compatibility with ISO holders

Compatibility with toolholders is determined by form, clearance angle, tolerance class, fastening, size and thickness; the ISO designation simplifies holder selection. The insert is supplied with a cylindrical hole plus a one‑side countersink (40°–60°) for standard clamping systems and quick, reproducible mounting. For best results, pair the insert with a matching external holder or boring bar, a suitable shim/clamp set and the correct screw; this system approach minimises set‑up time and supports safe, repeatable operation on production lines.

Targeted use and productivity gains

Engineered for external and internal turning, this insert performs especially well where interrupted cuts or increased chipping risk occur. Selecting the right one‑sided chipbreaker and the AH6235 grade according to workpiece material and machine rigidity will reduce cycle times and improve component quality. The combination of a tough substrate and PVD coating helps maintain a stable cutting edge, which can translate into fewer tool changes and higher overall productivity on the shop floor.

FAQ

Which materials is this insert best suited for?
The TPMT 090208 AH6235 Tungaloy turning insert is optimised for stainless steels and is recommended for interrupted cuts or applications with elevated chipping risk.

Which holders are compatible with this insert?
Compatibility is based on ISO geometry; use a triangle pocket holder for size 09 with matching clearance angle and clamp style to mount the TPMT 090208 AH6235 insert securely.

What does the hole and countersink specification mean for mounting?
The cylindrical hole with a one‑side countersink (40°–60°) on the TPMT 090208 AH6235 enables standard screw clamping and reproducible positioning in ISO‑compliant toolholders.

How should the chipbreaker and grade be chosen?
Select the chipbreaker and grade to match workpiece material and machining stability; the AH6235 grade is a tougher option suited to stainless steels and unstable cutting conditions.

Can this insert be used for finishing operations?
Yes—with the 0.8 mm nose radius and correct cutting parameters the insert can deliver consistent surface quality for finishing and semi‑finishing tasks.
