TPMT090202 GH730 turning indexable insert by Tungaloy — triangular 60° geometry

A TPMT090202 GH730 insert engineered for ISO-compliant turning, offering a compact 0.2 mm corner radius and a carbide substrate that supports stable cutting edges in a broad range of turning tasks.

• ISO triangular indexable insert
• Grade GH730 for wear resistance
• 0.2 mm corner radius, 60° geometry
• With central hole and 40°–60° countersink

Consistent production through a wear‑balanced grade

The GH730 grade is formulated to balance wear resistance, toughness and cutting‑edge stability, which translates into predictable tool life and fewer unplanned tool changes during turning. In practice, this balance reduces downtime and contributes to stable component quality over long runs. The carbide substrate and the grade’s wear characteristics mean the insert tolerates interrupted cuts and variable engagement, while the small 0.2 mm radius supports fine surface finish where low‑radius inserts are required. This combination is particularly suitable when repeatability and consistent surface quality are priorities.

Simple integration into ISO tool systems

As an ISO‑standard triangular insert, compatibility is defined by form, clearance angle, tolerance class, fastening method, size and thickness. The 11° clearance angle and the 60° seat geometry ensure correct seating in standard triangular holders, while the central hole with a cylindrical bore and one‑side countersink (40°–60°) enables secure clamping with common screw systems and clamping sets. The system approach—insert, matching external holder or boring bar, shim/clamp and replaceable fasteners—makes retrofitting and inventory management straightforward for production shops aiming to standardise tooling.

Practical benefits for process reliability and surface quality

The combination of grade and geometry delivers two clear benefits: extended service life under varied cutting conditions and improved edge integrity during higher mechanical loading. The 0.2 mm corner radius helps achieve finer surface finishes on external and internal turning, while the single‑sided chipbreaker must be matched to workpiece material and cutting parameters to control chip flow and avoid chip re‑cutting. Selecting the correct chipbreaker and the GH730 grade reduces flank wear and maintains dimensional accuracy, which supports higher first‑pass yields and lower rework rates.

Mounting, handling and economical tool use

With a plate thickness of 2.38 mm and a size designation of 09, the insert is compact yet robust for common turning tasks. The triangular form and the central hole design simplify indexation and secure clamping, enabling quick insert changes and minimal setup time. Proven grade characteristics mean fewer indexations per component produced, which reduces tooling cost per part and enhances overall process economy. Traceability is supported by the manufacturer article number and the supplier SKU for stock management and reordering.

FAQ

What is the GH730 grade designed for?
The GH730 grade is a Tungaloy carbide formulation that balances wear resistance, toughness and cutting‑edge stability to support reliable turning performance under varying conditions.

Which operations suit this insert best?
The TPMT090202 GH730 insert is intended for turning, including external and internal turning, where a small corner radius and stable edge life are required.

How does the insert fasten to the holder?
The TPMT090202 GH730 insert features a central cylindrical hole with a one‑side countersink (40°–60°) that enables screw clamping into compatible triangular holders or boring bars.

What surface finish can be expected with a 0.2 mm radius?
A 0.2 mm corner radius on the TPMT090202 GH730 promotes finer surface finishes on turned parts and is suitable for finishing and semi‑finishing operations when combined with an appropriate chipbreaker.

Which details are important for holder compatibility?
Compatibility depends on the insert’s form, 11° clearance angle, tolerance class, fastening type, size (09) and thickness (2.38 mm); ensure the holder matches these parameters for secure seating.
