CNGG 120404 GH110 indexable turning insert for Turning — Tungaloy

A CNGG120404 GH110 indexable turning insert engineered for ISO-compliant external and internal turning operations, offering a compact rhombic form and robust carbide grade.

*Rhombic 80° geometry for versatile turning
*GH110 grade for wear resistance and toughness
*Double-sided chipbreaker for repeatable performance
*Cylindrical hole and 0.4 mm corner radius

Consistent cutting performance for uninterrupted production

The ISO-standard indexable insert delivers predictable performance in serial turning applications. Manufactured from carbide and specified in the GH110 Tungaloy grade, the insert balances wear resistance and toughness, which supports longer in-process life and fewer interruptions. Compatibility with a holder is governed by form, clearance angle, tolerance class, fastening, size and thickness — parameters that determine correct seating and clamping in ISO turning systems. The rhombic 80° geometry and modest 0.4 mm corner radius promote stable cutting forces, helping to maintain dimensional accuracy over tool life.

Easy integration into existing ISO toolholders and setups

Designed to match common ISO turning systems, the insert’s rhombic shape, 12 mm inscribed circle and 4.76 mm thickness allow simple replacement in compatible external holders or boring bars. The cylindrical hole supports standard clamping and securing mechanisms, while the specified 0° clearance provides a defined contact geometry that helps avoid ambiguous seating. These measurable characteristics reduce setup time and support reproducible positioning, enabling faster changeovers and predictable tool behaviour in multi-shift production environments.

Stable chip control and surface consistency

The built-in double-sided chipbreaker and the GH110 composition contribute to controlled chip formation and evacuation under a range of turning conditions. Stable chip control reduces risk of surface damage and tool interference, which in turn supports consistent workpiece finish from pass to pass. The combination of geometry and grade is selected to harmonise cutting-edge stability with sufficient toughness, improving process reliability and lowering the need for frequent insert changes — a clear efficiency gain for batch and continuous machining.

Practical handling and selection guidance

When selecting this insert, pair the CNGG120404 GH110 with a holder that matches the insert form, clearance and tolerance class to guarantee correct seating and optimal cutting angles. The rhombic format and 0.4 mm corner radius are suited to finishing and medium finishing passes where small radii improve surface integrity. The insert’s double-sided layout extends indexable life and reduces inventory needs. For material-specific recommendations or to verify holder compatibility, consult technical advisory resources or the dealer for tailored cutting data.

FAQ

What operations is this insert recommended for?
The CNGG120404 GH110 insert is designed for ISO-compliant external and internal turning operations where a rhombic geometry and a 0.4 mm corner radius support finishing and medium-finishing passes.

How does the GH110 grade affect performance?
GH110, as applied by Tungaloy, provides a balance of wear resistance and toughness that promotes stable cutting-edge life and reliable chip control in repeated turning cycles.

Is the insert compatible with standard ISO holders?
Compatibility depends on holder form, clearance angle, tolerance class, fastening and thickness; the CNGG120404 GH110 fits holders designed for ISO CNGG-type inserts with a 12 mm inscribed circle and 4.76 mm thickness.

How should the insert be clamped?
The cylindrical hole and ISO geometry allow standard screw or clamp systems used for rhombic indexable inserts; correct clamping relies on matching the holder’s tolerance class and seat geometry.

Can the insert be indexed to use both faces?
Yes, the insert is double-sided with a chipbreaker on each face, enabling indexing to the second cutting edge to extend usable life.
