TNMG 220408 GH330 turning insert by Tungaloy — 0° clearance, 0.8 mm nose radius

The TNMG220408 GH330 is an ISO‑standard triangular turning insert designed for external and internal turning, offering a robust carbide substrate and a chipbreaker geometry suited to varied turning operations.

• ISO‑standard TNMG220408 geometry for easy fitting
• GH330 Tungaloy grade for wear resistance and toughness
• 0° clearance with 0.8 mm nose radius for precise cuts
• Double-sided chipbreaker in triangular 22 mm form

Stable cutting performance through tailored grade and substrate

The insert uses the GH330 cutting grade on a hardened carbide substrate to combine wear resistance with sufficient toughness, reducing edge chipping under typical turning loads. This balance extends service intervals and supports consistent component tolerances in series production. The supplied chipbreaker geometry is designed to control swarf formation and maintain surface quality; when paired with the correct feed and depth of cut, the result is a measurable increase in process stability and predictable tool life.

Secure clamping and straightforward compatibility for quick changeovers

As an ISO‑standard insert, the geometry and dimensions—22 mm size, 4.76 mm thickness, 60° included angle and a cylindrical hole—ensure compatibility with a wide range of ISO turn‑holders. The 0° clearance specification and triangular form fit common holder profiles; compatibility depends on form, free angle, tolerance class, fastening and thickness. Double‑sided use provides two effective cutting edges per index, improving economy per part produced while the central hole and standard form guarantee secure clamping and repeatable seating.

Practical machining advice and benefits for production

A 0.8 mm nose radius offers a compromise between profile accuracy and edge strength: suitable for general turning, finishing passes and moderate profiling without excessive tool stress. The double-sided chipbreaker allows economical indexing and is recommended to be matched to workpiece material and stability of the setup. For roughing, select a more robust feed and ensure coolant and clamping stiffness are adequate; for finishing, reduce feed and take advantage of the insert’s edge stability to achieve improved surface finish. The overall effect is reduced downtime and predictable throughput in machining cells.

FAQ

What work does this insert suit best?
The TNMG220408 GH330 turning insert is intended for general turning operations, including external and internal turning where a balance of wear resistance and toughness is required.

Which materials can be machined with this grade?
The GH330 grade on a carbide substrate is suitable across a broad range of steels and alloyed materials; chipbreaker choice should be matched to the specific workpiece material and operation.

How many effective cutting edges does the insert provide?
With a double‑sided chipbreaker and triangular form, the insert provides two usable edges per side, enabling multiple indexings before replacement.

What is the effect of the 0.8 mm nose radius?
A 0.8 mm nose radius improves edge strength and delivers a balance between surface finish and profile fidelity; it is versatile for both finishing and medium‑duty profiling.

How is compatibility with holders ensured?
Compatibility is determined by geometry, free angle, tolerance class, fastening, size and thickness; the ISO‑standard dimensions of the insert support straightforward matching to ISO turn‑holders.
