TNMG220408 GH330 Turning Insert (TNMG 220408) — Tungaloy

TNMG220408 GH330 is a triangular, ISO‑standard turning insert designed for external and internal turning in a wide range of applications, offering high wear resistance and stable cutting‑edge behaviour.

• TNMG220408 GH330 ISO turning insert
• 60° triangular geometry for secure clamping
• Double-sided chipbreaker, cylindrical hole
• Cemented carbide grade GH330 for wear resistance

Consistent machining through ISO compatibility and geometry

The ISO conformity of this triangular insert guarantees interchangeability with ISO‑compliant holders and fixtures. The 60° point angle and the triangular plate form a stable support that reduces vibration in many turning set‑ups. Because compatibility depends on form, relief angle, tolerance class, fastening and size, the standardised specification reduces setup time and supports predictable machining outcomes. The included cylindrical hole and double-sided chipbreaker allow straightforward indexing and minimise downtime for tip changes, contributing to a constant production flow and lower overall process costs.

Durable carbide grade for longer tool life and process stability

The GH330 grade is a cemented carbide developed to balance wear resistance, toughness and cutting‑edge stability. In practice this yields fewer edge failures under mixed cutting conditions and more consistent surface finish over longer tool life. The combination of substrate and chipbreaker geometry helps maintain a stable cutting edge during interrupted cuts and varied feed rates, which translates into reduced rework and a favourable cost‑per‑component ratio. For workshops aiming to increase throughput while retaining dimensional quality, the material‑and‑geometry pairing delivers measurable efficiency gains.

Selection guidance and practical mounting considerations

For reliable performance, choose an insert geometry and chipbreaker that match the workpiece material, cutting conditions and machine rigidity. This insert is intended for turning and works with holders sized to the 22 mm plate dimension and the specified 0° relief angle; the corner radius of 0.8 mm influences achievable surface finish and allowable feed rates. If the machining task requires frequent indexing, the double‑sided design reduces tooling expenditure. If in doubt about holder compatibility, tolerance class or optimal cutting data, detailed matching and cutting parameter recommendations are available — please contact Metav Werkzeuge for tailored technical support by e‑mail or phone.

FAQ

What materials is this insert suitable for? TNMG220408 GH330 is a cemented carbide insert intended for general turning applications; the GH330 grade provides a balance of wear resistance and toughness suitable for a broad material range when the correct chipbreaker is selected.

How does the 60° triangular geometry affect clamping and cutting? The 60° triangular geometry delivers a secure contact area in ISO‑type holders, improving stability; this geometry in the TNMG220408 format supports reliable clamping and consistent cutting performance.

Can the insert be indexed multiple times? Yes, the double‑sided design allows multiple indexing positions; the TNMG220408 GH330 insert can be rotated to present fresh cutting edges, reducing tooling costs per component.

Which features assist chip control during turning? The double‑sided chipbreaker together with the GH330 grade and the insert geometry promote controlled chip formation and evacuation, which helps maintain surface quality and reduces the risk of chip interference.

Is the insert compatible with all ISO turning holders? Compatibility requires matching the insert form, relief angle, tolerance class, fastening and size; the ISO designation facilitates selection, but verification against the holder specification is recommended for best results.
