TPMT 090208 GH730 – ISO indexable turning insert for turning applications, 60° triangle, with hole — Tungaloy

TPMT090208 GH730 is an ISO‑standard triangular indexable insert engineered for general external and internal turning, offering a one‑side chipbreaker and secure clamping via a cylindrical hole with countersink.

• ISO triangle insert 60° geometry
• GH730 carbide grade for wear resistance
• 0.8 mm corner radius for finishing
• Cylindrical hole with 40°–60° countersink

Productivity gains from a wear‑resistant carbide grade

The GH730 grade, supplied in cemented carbide, balances wear resistance with edge toughness to extend cutting intervals in mixed‑material production. Selecting a robust grade reduces unplanned tool changes and stabilises machining processes, which translates into fewer interruptions and lower per‑part tooling cost. The controlled chip formation of the single‑side chipbreaker supports swarf evacuation in both light and medium cutting depths, contributing to a smoother cycle time and more consistent surface quality.

ISO compatibility and secure clamping for reliable repeatability

The TPMT090208 geometry conforms to ISO form and sizing for triangular turning inserts, ensuring compatibility with matching ISO toolholders when form, clearance angle, tolerance class, fastening and plate thickness are respected. Key dimensions — 11° clearance angle and a 2.38 mm plate thickness — determine seat fit and clamping stability. The insert’s cylindrical hole with a single‑side countersink (40°–60°) gives a repeatable seating position and secure retention under varying cutting forces, reducing vibration and producing predictable component tolerances.

Practical benefits: surface finish, tool life and application fit

A 0.8 mm corner radius provides a good compromise between edge strength and fine surface finish for finishing and semi‑finishing passes. The single‑side chipbreaker is optimised for turning operations, helping to break chips and protect the cutting edge under interrupted cuts. For production planning, the combination of the triangular 60° geometry and GH730 grade suits a broad material range in turning, enabling consolidated tooling inventories and simpler grade selection for mixed‑batch work, which supports leaner workflow and higher throughput.

FAQ

What materials is this insert suitable for?
The TPMT090208 GH730 insert is designed for turning and delivers good performance across a broad material range thanks to the GH730 carbide grade, offering a balance between wear resistance and toughness.

How does the chipbreaker affect machining?
The single‑side chipbreaker controls chip formation and evacuation during turning, which improves surface finish and reduces the risk of chip entanglement on external and internal turning tasks.

What determines holder compatibility for this insert?
Compatibility depends on ISO form, clearance angle, tolerance class, fastening type, size and plate thickness; the listed dimensions (11° clearance, 2.38 mm thickness) indicate the required holder seat and clamping arrangement.

Can this insert be used for finishing operations?
Yes, the 0.8 mm corner radius is suitable for finishing and semi‑finishing passes, providing a compromise between edge strength and fine surface finish.

What fastening does the insert use?
The insert features a cylindrical hole with a single‑side countersink (40°–60°) that secures the plate in standard ISO clamping systems and ensures repeatable seating.
