TPGT 16T304 GH330 Tungaloy indexable insert for Turning, triangular 60°

A TPGT16T304 GH330 indexable turning insert, engineered for reliable external and internal turning and designed to deliver stable cutting performance with a single‑side chipbreaker.

• ISO triangular insert TPGT 16T304
• GH330 carbide grade for balanced wear resistance
• 60° included angle, 11° clearance angle
• Central hole with 40°–60° countersink

Precision and consistent edge life for productive turning

The GH330 grade, combined with Tungaloy's carbide manufacturing, gives the insert a balanced blend of wear resistance and toughness, which translates into longer tool life and reduced regrinding intervals. The material selection and edge preparation promote edge stability, resulting in a more consistent surface finish and fewer rejects during serial production. Because the grade is tailored for turning, the result is predictable performance across a range of machining conditions and therefore more efficient process planning.

Geometry and mounting that ensure versatility and repeatability

The triangular geometry with a 60° included angle and an 11° clearance provides a versatile cutting profile suitable for many turning tasks. The 0.4 mm nose radius supports a compromise between strength and surface quality while the 3.97 mm thickness ensures rigidity in interrupted cuts. The insert is ISO‑standardised, which simplifies selection and matching with compatible holders: form, clearance angle, tolerance class, fastening method, size and thickness determine fit. The central hole and countersink secure repeatable clamping and positioning for consistent reference points in setup.

Operational advantages: chip control and streamlined system integration

Equipped with a single‑side chipbreaker, the insert improves chip control during external and internal turning, helping to avoid entanglement and facilitating safer automated operation. The ISO insert is intended to be used in a complete system—indexable insert, matching external holder or boring bar, backing/shim and replacement screws—to reduce changeover time and minimise mounting errors. Selecting the appropriate chipbreaker and GH330 grade according to workpiece material and machining stability will further raise productivity and reduce unexpected downtime.

FAQ

What turning operations suit this insert best?
The TPGT16T304 GH330 insert is intended for both external and internal turning; its geometry and GH330 grade make it suitable where a balance of wear resistance and edge toughness is required.

How does the GH330 grade affect tool life?
The GH330 grade from Tungaloy provides a compromise between hardness and toughness, improving edge stability and extending the insert’s service life under typical turning conditions.

Which holders are compatible with this ISO insert?
Compatibility depends on the holder’s form, clearance angle, tolerance class, fastening method, size and thickness; the ISO designation TPGT16T304 helps to match the correct external holder or boring bar.

What advantage does the central hole and countersink bring?
The central hole with cylindrical bore and a 40°–60° countersink ensures secure clamping, repeatable seating and simplified index changes, reducing setup time and positioning variance.

Can the chipbreaker be used for automated turning?
Yes, the single‑side chipbreaker improves chip control and is suitable for automated turning processes when paired with appropriate cutting parameters and stable fixturing.
