TPGT 130304 GH330 — Tungaloy ISO turning insert for external and internal turning

The TPGT130304 GH330 is a triangular ISO turning insert designed for general turning operations, offering a balanced mix of wear resistance and toughness for a wide range of workpiece materials.

• ISO triangular format TPGT130304
• GH330 Tungaloy wear‑resistant grade
• 11° relief angle for stable cutting
• 0.4 mm corner radius for edge strength

Improved productivity through grade and geometry

The combination of the GH330 cutting grade and a carbide substrate provides a reliable balance between wear resistance and toughness, which translates into longer tool life and fewer interruptions in production. The ISO geometry of the insert ensures predictable performance in a variety of turning tasks; selecting the correct chipbreaker and grade helps to match the insert to the workpiece and machining conditions, reducing cycle times and improving repeatability. For operations where a consistent cutting edge is required, the grade’s composition supports stable chip formation and resistance to abrasive wear.

Precise geometry for repeatable results

Designed as a triangular insert, the TPGT130304 features an included angle of 60°, a 0.4 mm corner radius and a 3.18 mm thickness, dimensions that contribute to edge strength and positional stability in the clamping system. The 11° relief angle reduces rubbing at the flank while maintaining cutting support, which helps to produce consistent surface finish and dimensional control. These geometric parameters make the insert particularly suitable for finishing to medium‑roughing passes where a controlled contact area and predictable tool deflection are important.

Secure mounting and system compatibility

Compatibility with a given holder is determined by form, relief angle, tolerance class, fastening method, size and thickness. This indexable insert is supplied with a cylindrical hole and a single‑sided countersink (40°–60°), enabling secure clamping in standard ISO holders and boring bars. The hole style and precise tolerances assist in repeatable seating and clamping, which reduces setup time and improves positional accuracy across multiple tool changes. When integrating this insert into a tool system, ensure the chosen holder matches the ISO form and fastening specifications.

Application range and handling guidance

Intended for turning operations, the insert’s single‑sided chipbreaker is optimised for controlled chip formation in many machining scenarios. While the TPGT130304 GH330 performs well across a variety of steels and alloyed materials, selecting the appropriate chipbreaker and cutting parameters for the specific workpiece increases efficiency and prolongs insert life. For unfamiliar applications or when machining abrasive or hard materials, consult process data sheets or Metav Werkzeuge’s technical advisors to determine optimal speeds, feeds and depth of cut for safe and productive machining.

FAQ

What turning tasks is this insert suited for?
The TPGT130304 GH330 insert is designed for external and internal turning operations; its geometry and grade allow use from finishing to medium‑roughing depending on cutting parameters.

How does the GH330 grade influence tool life?
GH330 provides a combination of wear resistance and edge stability, so the insert maintains a cutting edge under continuous operation and supports longer intervals between indexings.

Which holders are compatible with this insert?
Compatibility depends on holder form, relief angle, tolerance class, fastening and thickness; the insert’s cylindrical hole with countersink enables secure clamping in standard ISO holders designed for TPGT‑style inserts.

What does the 0.4 mm corner radius mean in practice?
A 0.4 mm corner radius increases edge strength and reduces the likelihood of chipping, making it suitable for slightly heavier cuts while still allowing a fine surface finish.

Is this insert ready to use out of the box?
Yes — the insert is supplied in the specified ISO geometry and hole style; correct seating and torque on the clamping screw are essential for repeatable performance.
