SNGG 090308 GH330 — Turning insert, 90° square, Tungaloy

The SNGG090308-01 GH330 is an ISO-format carbide indexable insert designed for external and internal turning, featuring a 90° square geometry and a 0° relief to suit a wide range of turning operations.

• ISO 90° square geometry
• GH330 grade for wear resistance
• 0.8 mm corner radius for robust edges
• 3.18 mm plate thickness for stability

Consistent tool life through balanced grade technology

The GH330 cutting grade from Tungaloy combines wear resistance and edge toughness to extend service intervals while maintaining process stability. The substrate is carbide, chosen for its hardness and resistance to abrasion; the grade composition optimises the trade-off between flank wear and chipping resistance. For production environments where predictable life and repeatable part quality matter, this formulation reduces unexpected interruptions and supports steady throughput. Selection of the appropriate chipbreaker complements the grade to manage swarf and surface finish.

Geometry designed for flexible external and internal turning

A 90° square plate form delivers versatile cutting angles for facing and cylindrical work. The 0.8 mm corner radius provides a durable cutting edge that withstands intermittent cuts and supports light to moderate depth-of-cut strategies. The insert's 3.18 mm plate thickness contributes to rigidity and vibration damping when mounted in a correctly matched holder. Because the insert conforms to the ISO turning plate family, compatibility is determined by form, relief angle, tolerance class, mounting style, size and thickness — allowing straightforward integration into existing tool systems while ensuring predictable cutting behaviour.

Integrating the insert into a productive tooling system

System assembly typically comprises the ISO indexable insert, a suitable external holder or boring bar, a shim/clamping set and replacement screws. The insert's cylindrical hole simplifies positive clamping and easy orientation during tool change. Choosing the correct holder geometry and clamping parts minimises runout and ensures repeatable positioning, which in turn enhances part accuracy and surface quality. For process planning, pairing the GH330 grade with the appropriate chipbreaker 01 and cutting parameters yields an economical balance of tool life and productivity.

FAQ

What materials is this insert intended for?
The SNGG090308-01 GH330 insert is specified for turning applications; the GH330 grade is formulated to balance wear resistance and toughness for a broad range of workpiece materials, while chipbreaker selection and cutting data should be matched to the specific substrate.

How does the 0.8 mm corner radius affect cutting performance?
A 0.8 mm corner radius increases edge robustness and reduces the risk of chipping in interrupted cuts; using this radius supports stable insert life without excessively increasing cutting forces in typical turning operations.

Which holders are compatible with this ISO-format insert?
Compatibility depends on holder form, relief angle, tolerance class, mounting method, size and thickness; choose an external holder or boring bar designed for ISO turning indexable plates of size 09 and 3.18 mm thickness to ensure correct fit and repeatable clamping.

What does the GH330 designation mean for process planning?
GH330 is a Tungaloy grade that emphasises a balance between abrasion resistance and cutting-edge stability; for process planning, combine the GH330 grade with an appropriate chipbreaker and cutting parameters to achieve an economical tool life and consistent surface finish.
