WNMG 080404 GH330 indexable turning insert, trigon shape, 0.4 mm radius — Tungaloy

WNMG080404-SS GH330 is an ISO-standard trigon indexable insert designed for external and internal turning in production and repair environments, providing predictable fitment and consistent cutting behaviour.

• ISO-standard trigon insert
• GH330 wear-resistant grade
• SS chipbreaker for stable chips

Predictable geometry and system compatibility for streamlined tooling

The trigon-shaped insert offers a compact seating surface that simplifies holder selection and inventory management. Thanks to the ISO-standard designation and a standardised hole position, compatibility with matched external holders or boring bars is determined by form, relief, tolerance class, fastening method, size and thickness. This standardisation reduces machine downtime by enabling rapid replacement and interchangeability across tool systems, while the cylindrical hole and defined plate thickness ensure secure clamping under repeatable conditions.

Extended life and reliable edge stability through GH330 carbide technology

Tungaloy's GH330 grade combines wear resistance with sufficient toughness to maintain edge stability under mixed cutting conditions. Manufactured from carbide, the grade is tuned to balance abrasive wear resistance and fracture resistance, which translates into longer tool life and fewer insert changes. For operations that prioritise consistent part quality and predictable tool costs, this wear-resistant composition delivers measurable benefits in productivity and process stability.

Controlled chip formation and surface consistency with SS chipbreaker

The integrated SS chipbreaker is engineered to produce short, controllable chips across a wide range of turning tasks, improving chip evacuation and reducing the risk of entanglement in tight bores or on complex workpieces. A 0.4 mm radius at the cutting corner provides a compromise between edge strength and surface finish, helping to dampen vibration and deliver repeatable surface quality. The specified 0° relief aligns the insert profile with holders designed for neutral geometry, supporting a broad set of cutting strategies from light finishing to moderate roughing.

Practical handling and reliable integration into tool systems

At 4.76 mm plate thickness and an included angle of 80°, the insert is robust enough for stable clamping while remaining suitable for a wide selection of ISO-compatible holders. The trigon form and the presence of a cylindrical locating hole make mechanical indexation straightforward, and the SS chipbreaker geometry complements the GH330 grade to reduce rework and waste. For workshops and production lines where consistency and process repeatability matter, this insert integrates seamlessly into established tool cycles.

FAQ

What machining tasks is this insert best suited for? This indexable insert is intended for external and internal turning and performs well in general roughing and finishing where a balance of wear resistance and edge stability is required.

How does the GH330 grade affect tool life and performance? The GH330 grade provides a combination of wear resistance and toughness that extends insert life while maintaining reliable cutting-edge stability under mixed cutting conditions.

Is the insert compatible with standard ISO holders? The insert follows ISO geometry for trigon plates; compatibility depends on the holder's form, clearance angle, tolerance class, fastening method, size and thickness.

What benefit does the SS chipbreaker provide in practice? The SS chipbreaker promotes short, controlled chips for safer evacuation and more consistent surface finishes in both external turning and internal operations.
