TPGT 16T304 GH330 – Indexable turning insert for precision turning (60° triangle, 0.4 mm radius) by Tungaloy

A TPGT 16T304 GH330 indexable insert designed for industrial external and internal turning, combining a robust Tungaloy carbide grade with ISO‑conform geometry for consistent mounting and predictable performance.

• ISO‑standard 60° triangular form
• GH330 grade for wear resistance and toughness
• 0.4 mm nose radius for precise finishing
• Cylindrical hole with single‑side countersink

Stable cutting and prolonged tool life through optimised carbide grade

The choice of GH330 as the cutting‑grade provides a balanced combination of wear resistance and toughness, reducing flank wear while maintaining edge stability under variable cutting conditions. For production environments where repeatable results and less frequent index changes matter, this grade helps to preserve dimensional accuracy and surface quality over longer intervals. The result is improved process reliability and lower cumulative tool handling time.

Accurate fit and predictable clamping for quick tool changes

Conforming to ISO‑standard geometries, the insert’s triangular form and dimensions allow straightforward integration into standard external holders and boring bars. Key specifications such as the 60° included angle, 11° clearance angle and 3.97 mm plate thickness support stable assembly and repeatable clamping. The insert features a hole with a cylindrical bore plus a one‑side countersink (40°–60°) to ensure secure fastening and consistent seat orientation, minimising the risk of misalignment during replacement.

Controlled chip formation and application guidance for turning

Equipped with a single‑sided chipbreaker, the insert promotes reliable chip control for a range of turning tasks; the chip geometry aids evacuation in both external and internal operations when matched to workpiece stability and cutting parameters. The 0.4 mm nose radius favours fine finishing and tight tolerance machining; for heavier material removal, consideration of a larger radius or alternate geometry is advised to balance strength and surface finish. Selection of the chipbreaker and cutting data should be aligned with machining strategy and the chosen holder’s rigidity to achieve optimal productivity.

FAQ

What materials is this insert intended for? The TPGT16T304 GH330 insert is specified for turning operations; the GH330 grade balances wear resistance and toughness for a wide range of turning tasks.

How does the 0.4 mm nose radius affect surface finish? A 0.4 mm nose radius on the TPGT16T304 provides finer surface finish and better dimensional control, while larger radii are preferable when higher metal removal rates are required.

Is this insert compatible with standard ISO triangular holders? Yes, the insert follows ISO‑standard geometry and is compatible with triangular external holders and boring bars when matched for size, thickness and mounting style.

What is the function of the hole and countersink? The cylindrical hole with a one‑sided countersink (40°–60°) on this insert ensures secure fastening and consistent seating in the holder to support repeatable clamping and orientation.

Which feature of the insert helps with chip control? The single‑sided chipbreaker included on the insert is intended to manage chip form during turning, promoting safer evacuation and reduced risk of entanglement in many machining scenarios.
